The Malabar 761 is a 60-ton tripod jack for commercial aircraft for Boeing & Airbus aircraft.
It is a single-stage hydraulic jack designed primarily for use in aircraft maintenance. It consists of a tripod structure, hydraulic cylinder assembly, reservoir, valve block assembly, hand pump assembly, tow handle, and swivel casters.
The jack leg pads are raised off the ground. The casters will retract, and the pads rest on the ground when a load is applied to the jack.
