RollOuts October 2012
Crawler carrier line
Rig Source Inc.’s new Terramac RT9 rubber-track, multi-purpose carrier has an 18,000-pound carrying capacity and is equipped with a 230-horsepower Cummins diesel engine. Available in open- and closed-cab options, the unit includes ROPS and FOPS components. Ground pressure when fully loaded is only 4.9 pounds per square inch. Easy-to-mount front and rear bolt-on attachments can accommodate a variety of applications. The unit has a 17-foot, 7-inch overall length and is 8 feet, 5 inches wide with a 9-foot, 3-inch height and 20-inch minimum ground clearance. Travel speed is 4.7 to 7 miles per hour with a 10-foot turning radius.
Mitas has extended its family of ERL/ERD tire sizes with the addition of new earth-mover tires for wheel loaders, dozers, graders, dumpers, and scrapers. The tire’s large surface area is said to improve the life of the tire. The ERL-50 tread is designed for rocky conditions. All of the new line is radial with a steel-enforced carcass and steel breakers. The tires are made in the Czech Republic and are available worldwide.
High-performance rubber door
Rytec Corp. says its new Powerhouse rubber door, premiered at MINExpo, is practically maintenance free. It is engineered without springs, counterbalance, or wear parts. Its drive system is capable of high speeds to enable rapid access and minimize building exposure. Should the door take a hit, it is said to release without damage and restore to full operation with just the push of a button. The engineered styrene butadiene rubber roll-up panel and heavy-duty construction are virtually indestructible, according to the company. It features tight, full-perimeter seals and resistance to wind loads, along with user safety protection.
Sleipner displayed its system for transporting tracked excavators in open-pit mines and quarries at MINExpo. The system is based on axles and heavy tires with ramps. With the aid of the system and a haul truck, an excavator can easily and quickly be moved to another location, reducing wear on the excavator’s undercarriage and tracks. There are 11 models covering excavator weights from 30 to 550 tons. Most models incorporate different ramp sizes to fit different excavator brands and models. The newest model, E550, is the biggest one and can move 550-ton and larger excavators.
