SH640 D – Roof Support Carrier

SH640 D – Roof Support Carrier

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.

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.

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

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

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

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

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

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

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.

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.

Each attachment is tested and performance rated.

  • Side shift forks
  • AFC chain reeler
  • Belt reeler
  • Cable reeler
  • Jib crane [static and slewing]
  • Work baskets
