Aluminium jacks combine light weight with high lifting capacity. The use of high tensile aluminium alloy allows lifting capacities of up to 100 tonnes resulting in a very favourable 1,8 tonnes lifting capacity per 1kg weight ratio.
Available in capacities from 6,5 to 100 tonnes
Operation of Yale hydraulic jacks is a very simple. Jacks are supplied ready for use, i.e. including hydraulic oil, operating lever and, where applicable, carrying handle and lifting claw.
