Tread of rolling deep for drive and sidewalls reinforced for timber haulage in forestry roads unsealed. Built for mud, steep gradients and freight heavys.
The tala is a of applications most demanding for the commercial tyres. Every trip comienza with a truck empty climbing forestry roads empinados and unsealed up to a plataforma where se freight the timber, then descending by those same roads with the gross maximum vehicle weight. The roads are estrechos, full of surcos, covered of mud or gravel suelta according to the temporada, and bordeados by tocones, rocks and debris that threaten sidewalls of the tyres at every step. None tyre of highway survives in this environment, e even the tyres of mixed service of use general often se quedan short in the drive and durability that the tala exige.
The dual workload cycle of logging makes tyre selection exceptionally challenging. Loaded logging trucks weigh 36,000 kg or more, exerting maximum stress on every tyre while navigating roads cut through forests with minimal grading. But the same truck that low slowly by a road forestry muddy a 24 km/h loaded must then perform a retorno empty in highway a 90-105 km/h, demanding a the tyres a performance aceptable in fuel economy and manejo a speeds where the patterns aggressive generate ruido, heat and wear accelerated. The better tyres for logging trucks handle this contradiction offering suficiente drive for sections of forestry roads with freight without sacrificar a performance aceptable in the return empty by highway.
The mud is the adversario constante. The forestry roads in regions logging of the noroeste of the Pacífico, sureste and noreste experimentan temporadas húmedas extended where the surface of the road se convierte in a mezcla of arcilla, material orgánico and water estanevery. The tyres need a geometry of tread autolimpiante that expulse the mud while the wheel gira, instead of compactarlo in emptys of the band and perder drive. The designs of open shoulder with wide channels lateral and blocks independent provide the better evacuation of mud, allowing that the tyre excave through the surface soft and find terrain firm below.
Hanksugi offers three models of tyres adequate for demands of logging operations. The tyre of drive of open shoulder HS68 provides the drive and the performance autolimpiante necessary in forestry roads muddy, with protection of grip against stones that prevents that the gravel perfore the belt package. The tyre of all-position of mixed service HS76 maneja the position of steering with protection reinforced in sidewalls against the rocks and tocones that bordean the forestry roads. The tyre of drive HS58, with your pattern clasificado M+S and laminations antipunctures, is built for the worsees conditions of roads encontradas in logging operations.
The logging trucks viven in two worlds, and the tyre must perform in ambos. Entender the demands of each tramo of the trip it ayuda a seleccionar tyres that offer the better compromiso between the performance all terrain with freight and the efficiency in highway empty.
The enfoque right is prioritise the performance in road forestry with freight and aceptar the compromisos in the return empty by highway. A tyre that it saca of a plataforma muddy loaded vale more that a that saves 2% in fuel during the return empty. El design of open shoulder HS68 offers the better equilibrio: suficientemente aggressive for drive in forestry roads but suficientemente civilizado for speeds of highway in the return empty.
Tyres of drive, steering and all-position seleccionadas for transport of timber, forestry roads and the dual workload cycle of operation all terrain with freight and highway empty.
Drive tyre of open shoulder with protection of grip against stones and four grooves of decoupling. The geometry autolimpiante of the band expels the mud in forestry roads. Footprint wide for drive in surfaces soft and sueltas under freight heavys of timber.
All-position tyre of mixed service with tread extra deep and protection reinforced in sidewalls. Maneja the rocks, tocones and desechos that bordean the forestry roads while offers a answer of steering estable in sections of highway.
Drive tyre with pattern M+S and laminations antipunctures. Design of taco aggressive that provides the maximum grip in plataformas muddy and forestry roads no improved where the drive tyres standard no can ganar grip.
The forestry roads feature a collection única of hazards for the tyres that no se find in no another application of transport. Entender these hazards and seleccionar tyres with features of protection adequate can brandr the difference between completer a freight and llamar a a truck of service of tyres in a road forestry remote where no existe coverage celular.
When se cosecha the timber and se open a road throughl bosque, the tocones typically se cortan a ras of the ground but no se retiran. With the tiempo, the erosion of the ground expone these tocones, and sobresalen in the carril of tránsito. A tocón that golpee the sidewall of a tyre even a speed moderada can cortar the rubber of the sidewall and exponer the plies of the cuerpo, carrying a a reventón. The raíces of árboles caídos can extendse by the surface of the road e impactar the tyre with force suficiente for romper the sellado of the bead or damage the rin. The tyres with construction reinforced in sidewalls, as the HS76, provide grosor adicional of rubber in the área of the sidewall that absorbe the impact and resists the cuts of stumps and roots.
The forestry roads in the noroeste of the Pacífico can recibir between 1.500 and 2.500 mm of rain annually. This satura the surface of the road and creates mud deep that can immobilise a truck logging loaddo. The grooves se forman by freight heavys repetidas, channelling the water and creating zanjas that atrapan the tyres and reduces the control of the steering. The áreas of plataforma where se loadn the troncos are particularmente vulnerables a conditions of terrain soft because the team heavy comprime and revuelve the ground. The patterns of band self-cleaning with wide channels lateral are esenciales for maintain the drive in these condiciónes. El design of open shoulder HS68 allows that the mud is expulsado of the band while the tyre rota, maintaining the biting edges that grip throughl mud up to the surface firmr below.
The surfaces of forestry roads are typically compuestas of material available localmente, that can incluir rock angular sharp that short and astilla tread rubber. En áreas logging of mountain, road surfaces may include fractured granite, basalt or shale with edges it suficientemente sharp for cortar the compounds standard of tyres. The rocks also se acumulan in grooves of the band and perforan the rubber towards the belt package if not expelled. The features of protection of grip against stones, as the of the HS68, include plataformas in bottoms of grooves that avoidsn that the stones alcancen the depth necessary for contactar the steel belts. Checkr the grooves of the band in busca of stones alojadas in each parada is a hábito simple that prevents costsos damage to the belts.
The forestry roads se construyen to access the timber, no for meet with standards of slope of highway. The slopes of the 10 to the 15 percent are common, and some roads of arrastre approach 20 percent in sections short. Descender a slope of the 12 percent with 36.000 kg of gross vehicle weight requires a braking sustained that generates heat intenso both in brakes as in tyres. The drive tyres absorben gran part of this energy of braking, and the temperature interna can increasesr quickly during a descent long with load. The pressure of proper inflation is crítica for managing heat during descents. The tyres with low inflation flex more, generate more heat and have more probabilities of sufrir a separation of belt or reventón during or inmediatamente after of a slope long with load. The HS58 usa laminations antipunctures that agregan refuerzo structural more beyond of the belt package standard, providing a margin of safety adicional during descents of high tension.
Every position in a truck logging enfrenta different demands. Emparejar the tyre adequate a each position maximiza the life of each tyre to the time that ensures that the truck tenga the drive and the manejo necessary for operar with safety in forestry roads.
The steer tyres in a truck logging must offer a manejo receptivo in forestry roads estrechos and winding where a giro fallido can sacar to the truck of the road and between the árboles. Al same tiempo, need sidewalls reinforced for sobrevivir to the contact with tocones and rocks along of the edge of the road. The tyre of all-position of mixed service HS76 provides the protection in sidewalls that the tala requires without comprometer the precision of steering necessary for curvas cerradas of forestry roads. Your band deep offers life extended even to the speeds slow and the giro constante that characterise the driving in forestry roads.
The drive tyres are the workhorse of a truck logging. They must transmit engine torque to the surface of the road in mud, gravel and loose soil while supporting the weights maximum of the axle in each trip with load. The failure of drive in a tyre of drive loaded climbing a slope can result in the truck se deslice towards atrás, creating a situation extremadamente peligrosa. El design of open shoulder HS68 provides drive reliable in conditions variables with geometry mud-clearing. For the worsees condiciónes, the tyre of drive M+S HS58 offers the maximum grip with laminations antipunctures that protect against the rocks and desechos incrustados in surfaces of forestry roads.
The trailer tyres logging must manejar the weight concentrado of a freight complete of timber while siguen the grooves and the mud of forestry roads. Many trailers loggings usan configurations tandem or tri-axle for distribuir the weight of the timber, and each tyre must withstand your part proporcional. The tyres of the trailer also supporting the same hazards of tocones and rocks that the of the tractor, but with less visibility of the conductor. Para trailers loggings that also recorren sections of highway, a tyre of all-position that maneje ambos environments is the better option. Maintain the proper inflation on all positions of the trailer is crítico because the trailers loggings experimentan higher variation of weight that the trailers of freight standard conforme the freight se asienta during the transport.
The logging trucks in Australia typically use the nexts sizes of commercial tyres. The size right depends on your truck's configuration, the capacityes of the axle and the freight useful maximum of timber that your operation requires.

The logging operations often se perform in áreas remotas where the service of tyres is a horas of distance. A failure of tyre in a road forestry means the loss of production of all a day, more the cost of service of emergency a fees of áreas remotas. The prevention through the maintenance adequate is much more economic that the repair of emergency.
The forestry roads castigan more a the tyres with low inflation that any another superficie. The combination of freight heavys, speeds slow and terrain uneven generates a heat internal intenso in tyres already comprometidas by low pressure. Check all the pressures of the tyres before salir of the yard each morning and take a inflador portátil for ajustes in the campo. Ajuste the pressures according to the weight of the axle loaddo, no according to estimates. A tyre logging well inflated resists better the impacts, sigue more recto in grooves and disipa the heat with more effectively that a that funciona even 10 PSI low.
While espera a that the loaddor arme your load, camine alrededor of the truck e inspeccione each sidewall of tyres. Busque cuts frescos, raspones and protuberancias that indiquen damage by impact of the último viaje. A cut in the sidewall that aún no expone the plies of the body can be monitored, but a cut that muestre cuerda white or metálica means that the tyre must be replaced before the próximo trip with load. Detectar the damage in the sidewall a time it allows programr cambios of tyres in the yard instead of lidiar with a reventón in a road forestry.
The gravel of forestry roads se aloja in grooves of the band and perfora the rubber towards the steel belts in rotationes repetidas. A sola stone can penetrar to the belt package within some few hundreds of kilometres if not removed. Check the grooves of the band during each parada of inspection and remove the stones alojadas with a tyre probe. This toma two minutos by tyre and prevents the damage to the belts that would destroy the powerl of retreading of the casing. The tyres with features of ejection of stones, as the HS68, include plataformas elevadas in bottoms of grooves that ayudan a avoid that the stones alcancen depth crítica.
A casing retreadable of tyre logging saves between the 40 and the 60 percent of the cost of a tyre new. But the conditions of tala are hard for casings, by which your preservation requires a stress deliberado. Remove the tyres before that the band se wear up to the belt package, even si the patterns of wear localizados create points delgados while the resto of the band aún has life. Maintain the proper inflation during all the service life of the tyre. Almacene the casings removed in a lugar fresco and dry, far of the luz solar and fuentes of ozono. Etiquete every casing with the number of truck, position and razón of removal. Visit our retreading page for learn aboutr the criterios of acceptance of casings Hanksugi and options of retreading.
Questions common about tyres for logging trucks, performance in forestry roads and choice of tyres for transport of timber.
The logging trucks need tyres with patterns of band aggressive for drive in forestry roads unsealed, construction reinforced in sidewalls for resistir damage of rocks and tocones, and depth of band adequate for service life under freight heavys a low speed. The positions of drive need designs of open shoulder or taco deep that se autolimpien of the mud. The positions of steering need manejo receptivo for forestry roads estrechos. All the positions need protection in sidewalls against the hazards that bordean the forestry roads.
The most of logging trucks in Australia usan tyres 11R22.5, 295/80R22.5 or 11R24.5. The 295/80R22.5 and 11R22.5 are the most common sizes in the market Australian. The 11R24.5 provides a little more than height to the ground for conditions soft. Ajuste the size of the tyre to the specifications of the manufacturer of your truck and weights real of the axle with the maximum freight useful of timber.
The mud llena the emptys of the band and prevents the tyre from gripping the surface of the road. The tyres with designs of open shoulder and groove spacing wider self-clean more effectively because the mud is expulsado while the tyre rota. The tyres with M+S rating and aggressive open-shoulder patterns provide the better drive in mud. Maintain the proper inflation is especially important in conditions muddy because the tyres with low inflation se deforman and atrapan the mud instead of expelling it.
The truck tyreses loggings sufren damage in sidewalls by rocks, tocones and desechos that bordean the estrechos forestry roads. The tocones cortados nearby of the surface enganchan the sidewall when passes the truck. The rocks to the edge of the road feature edges sharp to the height of the sidewall. The tyres with construction reinforced in sidewalls resist better this damage that the tyres standard. Inspeccione the sidewalls before and after of each trip in forestry roads.
Yes, si the casing is in good condiciónes. The tasa of acceptance of retreading for casings logging is lower that for casings of highway due to the damage in sidewalls and the exposition a punctures. Maximice the powerl of retreading using tyres with sidewalls reinforced, maintaining the proper inflation, removing the tyres before that the band alcance the belts and reviewing the casings prontamente. A casing retreadable saves between the 40 and the 60 percent of the cost of a tyre new.
The logging trucks enfrentan a challenge único of work dual. Priorice the tyres for conditions of forestry roads with load, since is where the failures of drive and the damage a the tyres are more dangerous. Acepte that the patterns aggressive serán lightmente less efficient in fuel in the return empty by highway. The HS68 in drive and the HS76 in steering offer the better compromiso between the performance all terrain with freight and the efficiency in highway empty.
