WHAT HAPPENED
An Accident occurred when a Kerb Lifter lost compression.
An operative was laying splay kerbs using a Probst SM400 Stone Magnet c/w Splayed Kerb lifter on hire from Speedy hire. Before laying commenced the operative had checked the equipment, it was noted that the gauge was indicating full suction and had engaged the kerb, the operative attempted to manoeuvre the kerb into place using the lifter when suction was suddenly lost and the kerb fell onto the side of his foot, resulting in bruising to the last two toes of his right foot.

LEARNING POINTS / ACTIONS TAKEN
Speedy Hire examined the lifter and tested it. It was concluded that the pipe had bent causing the pipe to nip (SEE PIC 1) this caused the suction to build up in the pipe which showed on the gauge as suitable suction pressure, however there was little pressure at the kerb connection.
It was noted that to prevent the cable from nipping the pipe should be fed up into the body of the lifter as in (PIC2) this should be undertaken in a way as to prevent the hose from nipping.
In addition to this Speedy Hire are to approach the manufacturer to get them to put an armoured type hose onto the machine to prevent it from nipping.
CHECK BEFORE LIFTING AND BETWEEN LIFTS THAT ALL PIPES ARE FREE FROM NIP POINTS. CONTACT YOU SUPPLIER ABOUT REPLACING THE STANDARD PIPE WITH ARMOURED PIPING.
