Jacking and Skidding Equipment
Another way to move loads is by sliding or skidding (both names cover the same basic principle). For skidding, a skidding track is required. This is a steel track fitted with Teflon blocks. On top of the blocks a skid-shoe or beam is placed inside the track which has a stainless steel bottom and a load carrying structure on top. Teflon and stainless steel combined with lubricant
have a very limited friction, allowing large loads to be moved with limited force. The skid shoe is fitted with a horizontal push – pull cylinder which can be locked into a pair of slots fitted to the sides of the skidding track. The cylinder expands (usually one meter) and the load moves along the track accordingly. Then the cylinder is unlocked, retracts and is locked into the next pair of slots. This system is simple and strong, however it has specific limitations. The skid tracks can only be fitted in a straight line which limits maneuverability. The weight of the load is directly transmitted to the skidshoe and the track beneath. Therefore the entire track requires load spreading or foundation, which adds cost.
Mammoet has Strandjacks from 30T to 900T. A strand jack is a system similar to a jack, however in this case the load is not pushed up, but the jack pulls up a bundle of wires, which is called a strand. The system has two clamps: the bottom clamp is fixed and the upper clamp is connected to a hydraulic cylinder that can move up and down. Both clamps are gripping a steel wire. To start lifting the bottom clamp releases the wire and the top clamp is pushed up hydraulically whilst gripping the wire, which thus also moves up. Then the bottom clamp grips the wire, the top clamp is released and the hydraulic cylinder is retracted. Once fully retracted the top clamp grips the wire again and the bottom clamp is released. The load is lifted upwards by repetition of this sequence.
