Notes to accompany Terex Information Bulletin: Operating on side slopes (May 2014)

The main issue for cranes being used on mining sites is that operators equate flat ground with level ground, and do not de-rate their loads according to manufacturer’s instructions. A 20 mm height differential between the left and right side of the crane (1% side slope) can be sufficient for the de-rating requirement to apply.

Staying within this tolerance can be difficult to achieve in a concrete-floored warehouse, let alone on the ground on mining operations. The problem is exacerbated when the crane is being moved with a load, and the load starts swinging.

Following consultation with the Department of Mines and Petroleum, these notes were developed to accompany Terex Information Bulletin: Operating on side slopes issued 14 September 2007.

Terex Information Bulletin: Operating on side slopes (September 2007)

The principal employer at a mine site should maintain an awareness of the requirement for operators of pick-and-carry cranes to routinely reduce loads when encountering variable terrain. Terex issued the following de-rating bulletin on 14 September 2007. Where a crane does not have de-rating guidelines or deration charts, operators should request these from the manufacturer.

3M - Versaflo Powered Air Purifying Respirator (PAPR), TR-300 (April 2014)

When significant non-uniform localised pressure is applied to the TR-300 PAPR cover, there is the potential for leakage between the motor blower unit and P3 particulate filter housing. Testing indicates leaks resulting from localised pressure are temporary and diminished when the directed pressure is removed.

3M wishes to emphasise that this potential occurrence does not affect the TR-300 PAPR respiratory protection approvals and protection factor claims.

Ridgid - Proper use of pipe wrenches (October 2005)

Pipe wrenches are sometimes modified and used within industry in a manner inconsistent with the wrench manufacturer’s safety precautions. Guidance published by one manufacturer clearly states that modifying a pipe wrench or using a power drive to apply force to the handle of a pipe wrench can result in wrench failure and serious injury.
