SWLSWL Series Wormwheel Screw Hoists (SWL2.5–SWL35, JB/T 8809)
SWL Worm Screw Jack DONLY
SWL wormwheel screw hoist (screw jack) to industry standard JB/T 8809-1998: a worm gear with arc-profile cylindrical worm drives a trapezoidal screw. Seven models SWL2.5–SWL35 with 25–350 kN load capacity and Tr30×6 – Tr110×16 screws. Two ratios: normal P (6:1 – 10 2/3:1) and slow M (24:1 – 32:1); permissible power 0.55–6 kW, input speed up to 1,500 rpm, lifting speed up to 2.7 m/min. Type 1 — the screw rotates and travels; type 2 — the nut travels; assembly A (up) or B (down), four screw-end designs, bellows cover and anti-rotation. Normally self-locking at standstill.
