Although acceptable to LR, this test at reduced load may not be acceptable to some National Authorities. – Where it is not practicable for the crane to raise the full test load, as may be the case for hydraulic cranes, a reduced test load may be accepted, but in no case is this to be less than 1,1 x SWL. In the case of a variable load-radius crane, the tests are, generally, to be carried out for the appropriate safe working loads at maximum, minimum and an intermediate radius. – During the test, hoisting and slewing operations are to be carried out at slow speed. The test is to be carried out using certified weights suspended from the cargo hook or lifting attachment, according to a procedure agreed with the Surveyor.

Initial load test with a test load in accordance with Table below. – For cranes used for cargo and/or handling of tender boats (according to ILO): The load to be applied shall be the mass of the survival craft or rescue boat without persons on board, except that, at intervals not exceeding five years, the test shall be carried out with a proof load equal to 1.1 times the weight of the survival craft or rescue boat and its full complement of persons and equipment. – For cranes used only as Rescue Boat Launching Appliances on vessels of 500GT and over (according to SOLAS):Īnnually subjected to a dynamic test of the winch brake at maximum lowering speed.

The appliance and its attachments should also be tested dynamically to 1.1 times the working load. Acceptable factors of safety are 6 for wires, hooks and sheaves, and 4.5 for the remainder of the launching appliance. The launching appliance and its attachments should be constructed to withstand a static proof load on test of not less than 2.2 times the maximum working load. – For cranes used only as Rescue Boat Launching Appliances on vessels under 500GT (according to LY3): Please see below for the guidelines as advised by Lloyds: It is vital that when testing your equipment you contact qualified and certified LEEA inspectors for insurance, class, and the safety of all on board. Are you aware of the regulations for testing new cranes?
