HJ50-50, Heavy duty hydraulic jacks are 50 tons capacity with a 50mm stroke (hydra-jacks) which are ideal for many operations, such as bridge bearing replacement or temporary propping systems, the load can be mechanically held for long periods by locking the safety collar, available for sale or on hydraulic jack hire.

Hydra-Jacks are normally installed in between steel surfaces, bearing directly against concrete requires the use of steel spreader plates (200x200x40thick top and 200x200x20thick bottom). Its always better to leave a little too much headroom rather than not enough, use some of the jacks stroke to re-close the gap, the ideal installation height (gap) for this jack excluding any packing plates should be between 180 to 185 mm.

Using a single or pair of jacks with a single pump is relatively simple, however, multiple jacking requires the use of electronic monitoring and control systems to enable precise control of each jack. Special care must be taken when lifting structures such as bridges or buildings, please contact us for further advice.

Each individual hydraulic jack is fully load tested prior to dispatch, test certificates are issued with this product, however, caution must be taken when using high pressure hydraulics, induction training is required.
