Large Cross-section Pressure-resistant Trapezoidal Screw Pair
Equipped with thickened 40mm trapezoidal screw and centrifugal cast tin bronze worm gear. Carburized and hardened gear teeth with widened bearing areas hold heavy workpieces steadily, and self-locking performance remains stable under continuous vibration.
QT500 Ductile Iron Housing with Reinforcing Ribs
One-piece cast body with three-dimensional external ribs for outstanding impact and deformation resistance. Large single-end flange enables direct installation of high-power drives, while the emergency hand crank port is arranged in separate area.
Multi-layer Isolation Sealing for All Working Conditions
Multi-lip composite oil seals on both housing ends, extended thickened dust bellows for screw rod, and oil-resistant sealant filled at housing joints. Triple barriers block cutting fluid, metal dust and moisture for dusty and heavily polluted workshops of machine tool and metallurgy industries.
Single Unit Meets Medium & Heavy Jacking Demands
5-ton static rated load eliminates parallel arrangement of multiple jacks. It cuts equipment quantity compared with 2.5T models, simplifies lifting structure layout and reduces purchasing cost of matched bevel gearboxes and drive shafts.
High Rigidity for Long Stroke with Tiny Lateral Deflection
Thickened screw greatly improves bending resistance, delivering slight swing within 3-meter standard stroke. Matched with external guide bases, it fits high-precision leveling procedures for heavy molds and large test benches.
Strong Compatibility for High-power Drives
Oversized input shaft connects motors within 4KW directly, and geared motors can be matched to amplify output torque. Even torque distribution during multi-jack linkage avoids unbalanced load and jamming, ideal for heavy synchronous lifting platforms.
Q: What continuous working load range is allowed for long-term reciprocating lifting of SWL 5T jack?
A: 5 tons only refers to static rated load. The load should be limited within 3.5 tons for non-stop reciprocating operation. Instant impact load cannot exceed 4.5 tons to prevent permanent indentation and failure of worm gear teeth.
Q:The maximum standard stroke of 5T screw is 3 meters, what solution for heavy-duty ultra-long travel?
A: Custom double-stage telescopic screw is the top choice for travel over 3 meters, equipped with external guide sleeves to reduce screw bending and shaking during operation.
Q:Can servo motors be directly matched with this 5T screw jack?
A:Custom servo adapter flanges support direct connection without extra transition plates. High-temperature resistant grease is recommended for frequent servo start-stop cycles to relieve heat abrasion from high-speed meshing.
