Overview
There are few roof support carriers rated at 40 tonnes (44 tons) capacity. Only one carries this load at these speeds while maintaining flexibility and a small roadway presence. The SH640 D is a compact yet powerful roof support carrier that negotiates tight bends as well as steep gradients and uneven floor conditions. The compact Cat SH640 D diesel roof support carrier was developed to suit cramped mine conditions. It carries a massive 40 tonnes (44 tons) on standard forks. The design focuses on haulage of longwall roof supports and heavier ancillary components of the longwall.

Benefits & Features
Diesel for Endurance
Proven Yet Improved
- Cat diesel vehicles across the product range share industry-proven drive units; diesel engines and other major components from the world's leading OEM manufacturers. We combine this with our own expertise in developing low-emission solutions:
- Particulate filtration system
- Inline purifier catalytic converter
- Zero-smoke dry particulate exhaust system
- New wet scrubber exhaust system
- Posistop brakes for extra safety
- Positorque axles for superior traction
- 4-speed power shift transmission for smooth operation
The Power You Need
Diesel-powered roof support carriers carry your roof supports the full distance at maximum speed and lowest cost. Diesel equipment is a good option for new longwall installations as they do not require electrical infrastructure such as cabling and charging stations and can operate at higher speeds over long distances, up steeper gradients and over rougher terrain - conditions not suitable for battery-powered vehicles.
Diesel Power for the Long Haul
There are many technical features of Cat diesel vehicles that make them unique in the underground mining industry. Their general body air emissions are one of the lowest in the field, and the fact that they are compact, powerful machines with a small roadway presence and the capability to be used for multiple tasks means a high return on investment.
Flexibility
The four-wheel drive and rear engine arrangement are designed to offer high stability and high tractive effort whether loaded or unloaded on the roadway or installing roof supports at the longwall face.
