Reinforced Integrated Heavy-duty Housing
The housing is integrally cast with thickened ductile iron, with enlarged diameter screw and worm shaft. It stably bears a rated load of 25 tons and withstands long-term heavy pressure, suitable for heavy forging and large steel structure lifting.
Dual Self-locking Safety Mechanism
Double protection combining worm gear self-lock and trapezoidal thread self-lock firmly locks heavy loads after power cut. The screw will not sink even under slight reverse tension for higher safety margin.
Modular Expandable Structure
Standard connecting flanges are reserved on the body. It can work independently or form multi-unit lifting sets with steering gears and transmission shafts. Two types including translating screw and rotating nut are optional for various equipment spaces.
Impact Resistance & Anti-deformation
Core transmission parts are quenched and carburized. They resist bending and deformation under lifting impact and uneven loads, with stronger capacity to withstand sudden loads and lower failure rate than small-tonnage jacks.
Multiple Power Compatibility
It matches handwheels, ordinary reduction motors and high-power servo motors. Users can select power sources based on lifting speed and precision requirements to switch freely between manual and automatic modes.
Flexible Optional Protection Parts
Telescopic dust covers, waterproof sealing rings and upper & lower limit sensors can be equipped as required to improve protection level without modifying the body for outdoor, dusty and humid workshops.
Q: Will unbalanced side load damage the screw of SWL 25T jack during long-time lifting?
A: Eccentric load will cause uneven abrasion on the screw. Multiple jacks are recommended for load sharing. If only one unit is available, the eccentric load shall not exceed 30% of rated load.
Q:What's the maximum customizable stroke of SWL 25T screw jack?
A:The maximum standard stroke without support is 500mm. With external guiding supports, extended stroke up to 1200mm is available without screw shaking during operation.
Q:What anti-corrosion configurations are needed for SWL 25T used outdoors?
A:304 stainless steel screw, heavy anti-corrosion paint on housing and fully closed waterproof telescopic cover are required to resist rain, dust and mild outdoor corrosion.
