Do you offer a lighter alternative to regular steel jacks?
Hydra-Slide supplies both Steel jacks in capacities ranging from 50 tons to 200 tons as well as Aluminum jacks that are about half the weight of standard models (50-150 tons). you can see the specification sheet on our Aluminum jacks Here. We also offer Climbing Jacks in various capacities.
When would I use a Climbing Jack?
Climbing jacks are most advantageous in situations requiring higher lifts or where you want to jack using single blockpiles. Climbing jacks require only a single blockpile for each jacking point as opposed to conventional jacking that requires a jack pile and a separate support pile. This also eliminates the effect of timber piles compressing and expanding as the load is alternately put on and off the piles.
How do they work?
A climbing jack incorporates an inverted double-acting cylinder inside a special wide housing. The rod has a wider foot attachment.
As the cylinder is extended, Ekki timbers are placed under the sides of the housing. The cylinder is then retracted and more Ekki timbers are placed under the rod foot. The cylinder is extended again and this time a row of Ekki is placed under the housing but at 90⁰ to the first row. This sequence is continued until the load reaches the desired height. For lowering a load the above sequence is simply reversed.

What if I need to rotate a load?
We provide Engineered heavy load turntables for rotating items such as transformers or generators during handling or installation with capacities from 150 to 500 tons. They incorporate a reversible, hydraulically powered rotating mechanism for precise control.
OUR EKKI TIMBERS
What is the difference between Ekki wood and other traditional jacking timbers?
This wood has exceptional strength and resistance to crushing or bending and is ideally suited for jacking and blocking applications. Ekki is a West-African hardwood that is over 3 times stronger than white oak or fir. It is naturally resistant to insects, is non-porous and does not rot. Our timbers are a standard size of 10cm x 10cm x 1.0 m and weigh only about 11kgs each. (4″ x 4″ x 40″ x 25 lbs). They are much smaller, lighter and easier to handle than conventional timbers. See the Comparison Chart between different woods Here.
Is Ekki more expensive than other jacking timbers?
As an initial investment Ekki is more expensive than other traditional woods, however it will last for years without becoming structurally compromised, and they save time by being much lighter and easier to use for blocking and jacking applications.
