Industry and Investment NSW has issued a safety bulletin to the mining industry concerning the use of light vehicle service hoists.
According to the Department, many mines are now installing the hoists to improve the availability of site vehicles.
The mines are typically installing two-post and four-post hoists.
However, the Department said there have been a number of recent incidents where the vehicles have become unstable on the lifting arms of two-post hoists and fallen off.
“All mines operating two-post light vehicle hoists should ensure the wire balance ropes used by these hoists are thoroughly inspected by competent people and are correctly adjusted,” the Department said.
“Personnel need to be are aware of the centre of gravity for each type of vehicle to enable them to correctly position the lifting arms and ensure the load is in equilibrium prior to lifting.
“They should also have an understanding of centre of gravity changes and the likely consequences if components are removed or added while servicing.”
Industry and Investment recommends that all mines consider the AS 1418.9:1996 Cranes – Vehicle Hoists standards, prior to purchasing a hoist.
The mines must also refer to the design registration compliance requirements contained within clause 136(3) of the Occupational Health and Safety Regulations 2001.
The Department also recommends that mines observe the information on the selection, operation and maintenance of vehicle hoists found within AS 2550.9:1996 Cranes – Safe Use – Vehicle Hoists.
