SH660 HD – Roof Support Carrier

The SH660 HD is the current heavy capacity Shield Hauler and has been developed to carry 60 tonnes on the cookie plate. The design has been focused on the haulage of roof supports and the heavier ancillary components of the longwall. Vehicle dimensions are crucial in underground roadways, so the SH660 HD is designed to be compact, with a minimum profile and roadway presence.
