Product Features
1. The Electric Mobile Hydraulic Lifting Puller is widely used in factories, oil fields, shipyards, ports, railways, construction sites, tunneling operations, and for the removal of bearings, gears, couplings, and other large components.
2. Features a well-engineered structure, convenient operation, safe use, and fast installation and removal.
3. Equipped with an automatic hydraulic lifting system for convenient and accurate vertical positioning of the hydraulic puller. The entire system can be operated by one person. The hydraulic cylinder positions the jaws for removal, and the gripping force increases automatically as the pulling force increases, eliminating the need for additional chains to prevent the jaws from slipping or disengaging from the workpiece.
4. Mounted on a wheeled trolley for easy movement and convenient relocation between different working areas.
Hydraulic Puller Selection Guide
1. Measure the outside diameter, thickness, and required pulling distance of the component to be removed.
2. Where space permits, use a 3-jaw hydraulic puller whenever possible to provide a more secure grip and more evenly distributed pulling force.
3. Always select a puller with the correct capacity. If the component cannot be removed at the puller’s maximum rated force, use a higher-capacity hydraulic puller.
4. As a general reference, approximately 7–10 tons of pulling force may be required for each 1 inch of component bore diameter, depending on the fit and application conditions.
5. Always use an appropriate protective safety cover or safety blanket over the workpiece during pulling operations. High pulling forces may cause brittle components, such as cast-iron pulleys, to fracture and create flying debris hazards.
6. Apply pulling force gradually and steadily. Do not attempt to accelerate removal by adding extension bars or applying additional external leverage to the puller.
7. Use standard-length jaws whenever possible, as excessively long jaws may reduce the effective pulling capacity of the hydraulic puller.
