Equipment Supply Co. (ESCO) has added high tonnage/high lift jacks to its line of heavy duty hydraulic lifting equipment. Five new models are available with lifting capacity of 100–250 tons. All models are air/hydraulic powered and are balanced for easy moving on 13-in. pneumatic tires/wheels.

Lift extension saddles are stored in the jack base for easy adjustments to various lifting  heights of 5, 9 and 12 in. Stacking aluminum safety locking rings are an option, as is air-powered wheel drive for ease of positioning. All models are built with heavy duty lifting holes. Each jack has a maximum width of 23 in., allowing it to fit into tight clearance spaces. Lifting stroke on the five models ranges from 14.5 to 22.75 in.
