Regular Inspections are essential

Using lifting gear can often have a high risk of injury, and the cost to business can be significant when something goes wrong.

It is important to ensure that regular examinations and inspections of lifting gear are undertaken to ensure maintenance is kept, and to verify that the equipment can continue to be safely used.
