Setting up your mobile machine
The setup of a mobile crusher is the first and most important step before starting your crushing operation. Incorrect setup is unsafe and can cause extensive damage to your mobile crusher. A crusher that is not set up correctly will vibrate excessively and is prone to cracking in the chassis, walkways, handrails and guards. Excessive vibration also causes damage to the crusher mounting pads as well as electrical components. All of this results in unnecessary downtime and expensive repair bills.
The ground on which the crusher is to be set up must be level, solid and compacted. Do not use blasted material for the crusher pad. If necessary, use crushed rock that is then levelled and compacted. The ground must be capable of carrying the weight of the crusher.
Always follow your crusher manufacturer’s guidelines when operating and setting up your crusher. Once the crusher is on the pad, check that it is level to within 2 degrees left to right and 2 degrees front to back. Where fitted, lower the stabiliser legs until they rest on solid ground. The stabiliser legs are not designed to support the full weight of the machine while crushing. The weight of the machine must still be carried across the full length of the crawler tracks, with the stabiliser legs providing additional support.
When the crusher is in operation, check regularly for excessive vibration or movement of the crusher or chassis. If the ground gives way or subsides beneath the tracks or stabiliser legs, the crusher must be taken off the pad and the ground re-levelled and compacted.
A crusher that is set up correctly will extend the life of major components and give the sophisticated electronics the best chance of operating trouble-free.
