The 6-ton aluminum alloy lever hoist is a large-sized lever hoist with a rated load of 6 tons and a factory test load of 7.5 tons.Every aluminum alloy lever hoist will undergo corresponding testing before leaving the factory. The lever hoist will be tested with a pulling force of 1.25 times the rated load. Only if there are no problems can it be qualified before leaving the factory.However, in daily work and use, it cannot be used beyond the rated load, because the test load is to ensure the safety factor, and it must not be used overloaded.
