Brake and pawl The brake system needs a minimum load of 3% of the capacity. Only this minimum load makes sure that the load-pressure-brake closes correctly. When the brake closes correctly, the load is safely held GEFAHR! Working situations with no guarantee that the minimum load is charged, are forbidden! Commissioning General Should the unit be used in Germany:...
Functional test 10.1 Checks before the initial start-up Lifting gear Load chains must not be twisted. Lubricate the load chain with gear oil or suitable chain lubricant before first loading. Trolley drive The open-lying teeth of the trolley drive must be lubricated. Hand gear for hand geared trolley Ensure correct fit of the hand chain, it must not be twisted and must hang freely.
Inspection 12.1 Periodic checks Independently from the regulations of the individual countries, lifting devices must be checked at least yearly by a qualified person or licensed qualified person regarding its functional safety. 12.1.1 Components to be checked The following must be checked: Dimensions of load chain, load hooks, pawls, bolts, ratchet wheels, brake linings.
