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.
