The 2019 Morooka MST 3000VD is a rubber-tracked crawler carrier dumper built to haul and place material across ground conditions that stop wheeled trucks. Designed for soft, wet, muddy, or uneven terrain, this tracked dumper is commonly used on pipeline right-of-way work, wetland and environmental remediation, site development, road and bridge construction, mining and quarry support, and utility or transmission line projects where access is limited.

The primary advantage of the MST 3000VD is its ability to move heavy loads over sensitive or unstable ground. With a rated payload capacity of 33,000 lb and a ground bearing pressure of 3.6 psi empty and 7.1 psi loaded, it distributes weight broadly to reduce rutting and ground disturbance. A travel speed of up to 8.5 mph supports efficient cycle times on longer hauls, while the dump body handles aggregate, spoils, riprap, and general fill.

Notable specifications include a Caterpillar C7.1 diesel engine rated at 325 hp, an operating weight of 33,140 lb, 31.5-inch track width, and a 67-gallon fuel tank for extended shifts between refueling.

Contractors in pipeline construction, heavy civil and earthmoving, mining, forestry, dredging support, and environmental restoration typically rely on Morooka crawler carriers, as do rental fleets serving remote or seasonally soft job sites.
