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.

Sales Features

Diesel for Endurance

Cat diesel roof support carriers incorporate the most efficient engines and powertrains available while boasting the lowest level of general body air emissions amongst underground diesel vehicles. Many proprietary developments - such as dry scrubber and wet bath exhaust systems with diesel particulate filtration and horizontal or vertical configuration cooling radiators - make Cat diesel roof support carriers a safe and powerful solution for your longwall move. They can move any roof support over any distance and over various roadway conditions with speed and efficiency.

The Power You Need

A combination of Cat battery- and diesel-powered vehicles can offer the ideal solution for longwall installations and moves.

Diesel Power for the Long Haul

Diesel-powered equipment is used in nearly all underground mines in various tasks and functions around the world.

Flexibility

Cat diesel-powered roof support carriers offer independence and flexibility when you need it most - during longwall moves and reinstallation.

RAS - Rapid Attachment System

The Rapid Attachment System available for the CL10 and CL15 makes an accessory change a one-man operation, allowing a broad range of accessories to be fitted in moments without removing the backing plate. Utilizing the LHD with RAS attachments during longwall relocations can greatly reduce lost production time.
