Before using a new crane, it must be tested for the following functions:
- Hoisting and lowering
- Trolley travel
- Bridge travel
- Limit switches, locking and safety devices
- Rated load test
The trip setting of hoist limit switches will be determined by tests with an empty hook. The hook travels at increasing speeds up to the maximum speed. The actuating mechanism of the limit switch will be located so that it trips the switch, under any conditions. This must happen with sufficient time to prevent contact from the hook or block the hook with any part of the trolley.
