DBJ bottle jacks are hand-operated hydraulic jacks for general industrial lifting and pushing. The range runs from 10 to 50 ton, with short ‘S’ versions for tight spaces.
The 10 and 20 ton models have a screw extension for extra height. Most of them also work lying on their side, at about two-thirds of the normal stroke. An internal stroke limiter stops the piston from over-extending.
The DBJ-20A adds an air pump for faster lifting and comes with a three-piece saddle set. All models include an operating handle, and spare parts and seal kits are available.
