Proper foundations and support structures are essential to ensure the safe and efficient operation of quarry equipment

Crushing machinery needs a firm foundation on which t operate. This does not need to be a poured pad, but it may not be on unstable ground. When selecting the location, be sure that the entire area is as level as possible.

Follow all manuf acturer’s installation dra wings and specifications when constructing the base pads fo permanent plants.

If any questions arise re garding foundation requirements or modifications necessary for Jaw machinery, please contact the SBM Service Department.

Customer-designed support structures for Jaw equipment must meet SBM’s engineering standards. All plans must be submitted in adv ance to the Jaw Engineering Department for approval.


Quarry management is responsible for the proper installation and placement of guards to prevent personnel from coming in contact with rotating or moving parts.

In addition to the guards supplied with the machinery , additional guards and related safety equipment may be required to comply with OSHA, MSHA and any applicable local regulations. The proper fabrication, installation and placement of these items is quarry management’s responsibility.

When f abricating guards, refer to MSHA ’s Guide to Equipment Guarding at Metal and Nonmetal Mines. Additional information can also be provided by the safety officer at your orksite.

Never remo ve guards until the machinery is stopped, power is locked out, and controls are tagged. Be sure that guards are properly re-installed before reconnecting power.
