Setting up your mobile machineCreated: 2016-01-28

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 setup correctly, will vibrate excessively and is prone to cracking in the chassis, walkways, handrails and guards. The excessive vibration also causes damage to the crusher mounting pads as well as electrical components. All of this causes unnecessary downtime and expensive repair bills.
