The Terramac RT9 multi-purpose crawler carrier is designed for customization and versatility to tackle a wide variety of asphalt, aggregates, concrete, construction, earthmoving, lifting, mining and utility applications. The RT9 is the largest mid-sized rubber track carrier that does not require special oversize permitting to transport the machine, according to the manufacturer.

Manufactured in North America, the CE-certified Terramac RT9 carrier can be customized with an array of equipment, such as bark blowers, cranes, drills, flatbeds, generators and tanks. With an operating weight of 26,000 lbs. (11,794 kg) and a maximum carrying capacity of 18,000 lbs. (8,165 kg), the RT9 crawler carrier eliminates the need for additional equipment and minimizes environmental impact and restoration costs associated with job site ground damage.

"No matter what business you’re in — from aggregates, construction or earthmoving, to mining, oil and gas or utility — the Terramac RT9 crawler carrier can help you tackle any job site challenge that comes along," said Mike Crimaldi, CEO of Terramac LLC. "We can customize electrical power sources, frame adjustments and hydraulics on the RT9 to suit any configuration."

When fully loaded, the ground pressure on the RT9 is only 5.1 psi (0.36 kg/c2). Featuring a 10 ft. (3 m) turning radius, the rubber track crawler carrier has an overall length of 20 ft. (6 m), a width of 8 ft. 5 in. (2.6 m), a height of 9 ft. 3 in. (2.8 m) and a minimum ground clearance of 20 in. (51 cm). The unit can travel at speeds up to 6 mph (10 kmh).

Mining Applications

The standard RT9 features a dump bed, but for mining applications, it can be configured with a flat bed, water tank and hydraulic crane to handle drill sections. Power for the crane comes from the gear pump powering the dump bed.

The Terramac RT9 can be mounted with a spray boom for dust control on mine roads. The machine’s low ground pressure makes it ideal for loose and wet ground conditions where heavy, wheeled trucks are likely to get stuck. An RT9 equipped with a spray boom also can be used in agriculture applications requiring wet ground conditions.

Pipeline Applications

"On the pipeline right of way, there’s just dirt, no road," Crimaldi said. "When it rains, access for wheeled vehicles is terrible, but not for the RT9 track carrier."

In addition to carrying mats onto pipeline sites to create more stable working environments for larger construction equipment, the RT9 crawler carrier also is used for drilling, material handling and site investigation applications on oil and gas construction projects. The crawler carrier can be easily outfitted with a variety of tools and equipment, such as bark blowers, cranes, sandblasters and vacuum excavators to assist with pipeline construction.

"A welding machine attached to the bed of an RT9 crawler carrier can be removed in less than an hour," Crimaldi said. "Within a couple hours, one RT9 can be used for a variety of applications, which also makes our crawler carrier ideal for rental companies with customers looking to use the machines for multiple jobs. They can switch out the bed to match the customer’s specific needs."

Utility Applications

A digger derrick can be installed on the RT9 for digging holes and setting poles in remote, hard-to-reach locations. The RT9 also can be outfitted with a boom lift for lifting materials.

Geotechnical and Environmental Drilling Applications

For drilling jobs where access is challenging due to ground conditions, grade or working angles, the RT9 can be mounted with drilling rigs for a variety of environmental and geotechnical drilling applications, including soil boring, sampling and testing, monitoring and soil and groundwater remediation.

Because of the flotation from the RT9’s rubber tracks, contractors can keep working in all types of adverse ground and weather conditions, and can complete projects faster. The rubber tracks also allow for faster climbing on hills and reduced slippage in wet conditions.

"Unlike steel-track crawler carriers, the RT9 rubber-track crawler carrier won’t tear up the ground or road surface — a significant advantage for preventing costly job site ground damage," Crimaldi said.

The RT9 is equipped with a 230-hp (172-kW) Cummins diesel engine. Rollover protective structure (ROPS) and falling object protective structure (FOPS) are standard. Open- and closed-cab options are available.

Ideal for carrying supplies and materials, the bed on the RT9 elevates to a 48-degree angle for dumping gravel, sand, dirt and other materials. The bed can fold down, allowing the operator to side-load materials or equipment for carriage across rough terrain, delicate soil conditions and remote areas.

Designed with ease of maintenance in mind, the RT9 features a tilt hood providing easy access to key service areas. Terramac provides parts and service support — as well as custom fabrication and mounting services to install a wide range of equipment and configurations on the RT9.

Available for sale or rent, the Terramac RT9 crawler carrier can be ordered from the factory with the correct body configuration to accept custom accessories.
