Multi-stage hydraulic cylinder Poltek is a device used for lifting heavy loads. The main advantage of the hydraulic cylinder is its low overall height with a relatively high stroke. Hydraulic jacks are indispensable when installing or dismantling heavy equipment, structures, for lifting heavy machines and equipment from the plane, in construction, and are also used when repairing large units of various equipment. The main feature of jacks is that, unlike other lifting equipment (slings, hoists, grips), they work from below, not from above the load.
The jack's operation is based on the principle of oil pressure on pistons, due to which a large lifting force is achieved. The advantages of hydraulic jacks are high lifting capacity, smooth running, compactness and reliability of the design.
A distinctive feature of hydraulic cylinders is that they work in tandem with a manual, foot or electric oil station (pump).
Our company offers only high-quality products tested in real working conditions. All hydraulic jacks are tested before sale, are accompanied by a guarantee, passport and operating instructions.
Attention! Pump for inflation is not included in the kit. You can purchase it separately - Pump for hydraulic cylinders.
