Rubber Track Carriers Take On Steep Slopes and Soft Ground,

The transportation of earth and various materials resulting from work at mine sites presents a regular bottleneck given the remote access of such sites, and requires a lot of human labor. MOROOKA, a major distributor of rubber track carriers, feels that its vehicles can effectively solve the lion’s share of these troubles. This is because these carriers can perform efficient transport operations even on weak or severely inclined ground where ordinary trucks or other heavy vehicles dare not tread. This is because MOROOKA’s rubber crawler invention has proven its power for 60 years on all manner of terrain. “Our clients have found a way to work fast and secure without worrying about the terrain or environmental conditions. MOROOKA vehicles, thanks to their special transit system, do not get stuck, and can overcome steep slopes and unconsolidated soils. Their versatility makes them a very useful vehicle for many industries, especially mining,” says Raúl Valbuena, MOROOKA’s Operations Director for Mexico, Central America, and Brazil. According to Valbuena, companies are now able to take routes that were previously discarded due to the complexity of the topography

From its home base in Japan, MOROOKA has long focused on developing and perfecting transport vehicles for industry applications. The company’s carriers enjoy rubber crawlers and hydrostatic transmissions (HTS system) that combine to deal with challenging topographic conditions while maintaining vehicular stability. They are complemented by a hydraulic transmission gear which uses its own engine to drive the hydraulic pump and motor, helping the system to be more efficient and economical. This has helped products like MOROOKA’s carriers and dumpers become a regular sight on mine sites, trundling earth, sand, and other materials. “Our carriers exert minimal pressure on the ground. That is the secret to getting an enviable dynamic behavior but also to reduce the negative impacts on the ground,” Valbuena remarks. With an underbody inspired by ship designs and a bogie system that uses track rollers to absorb shocks from road beds, these vehicles are capable of achieving high speeds while ensuring safe operations. In addition, the rubber rollers have been tested under all sorts of conditions to ensure their ability to navigate steep, muddy, or snowy ground. This careful blend of design and efficiency has enabled MOROOKA to see its vehicles deploy in a wide variety of fields beyond mining, such as construction. The underbodies of specialized MOROOKA vehicles have also been adopted by international corporations for underground resources and geological surveys, power line maintenance, tunnel construction and similar activities. “The combination of a rubber track, and independent bogie assemblies with a HTS system results in a machine that is virtually unstoppable. As the bogies respond to varying ground conditions, contact with the surface is constantly maintained providing an unmatched traction that can overcome any operational challenge,” adds Valbuena.

“We have expanded the range of possibilities for operators looking to relocate and transport materials within a mining property and other applications. Our solutions have become favored in the mining industry for the transport of personnel, of mobile workshops, of drilling equipment, and of piping systems,” Valbuena highlights. Some mining companies in Mexico have employed MOROOKA vehicles to transport the equipment used to weld different types of piping and to carry the spare parts needed to repair heavy machinery on site. “If something can be truck-mounted, it can be mounted on a MOROOKA. This is a distinct advantage to get heavy machinery or spare parts to hardto-access sites. The carriers can be adapted for specific purposes to help contractors become more productive, profitable, and environmentally friendly.” Another important application that has been entrusted to the rubber crawler carriers is to directly transport drilling rigs. According to Valbuena, drilling companies are now able to far more easily relocate rigs from site to site. Traditionally, exploration companies had to dismount a drilling rig, transport it manually or by truck, and then set it up again at the new exploration site. This resulted in important time losses and endangered the safety of the operators due to the weight of the components they needed to carry. By providing the ability to directly mount drilling rigs on its crawlers, MOROOKA has given exploration companies a versatile method to conduct continuous drilling operations. “With MOOROKA, exploration campaigns can be performed at a far higher rate in relation to traditional methods. The use of our machines results in significant time savings while decreasing the dependence on human labor,” Valbuena comments.

He adds that these vehicles not only improve life for mining companies, but also for their drivers. MOROOKA used Caterpillar cabins with safety and comfort in mind, ensuring heating and air conditioning are present, while opting for a design that allows for maximum operator visibility and easy to use controls.
