Φ100mm Reinforced Load-bearing Screw
Equipped with large-diameter trapezoidal screw forged of quenched 42CrMo alloy steel, rated stable load reaches 35 tons. It fits heavy stamping machinery, water gates and large steel structure lifting with far higher bending rigidity than small-tonnage models.
Dual-speed Heavy-duty Transmission Pair
Two gear ratio options (standard & low-speed) are available. Integral cast high-tin bronze worm wheel and carburized hardened worm deliver stable low-speed high torque without rapid gear wear under long-term pressure.
Explosion-proof Compatible Input Flange
Standard IEC flange reserved for direct connection with flameproof motors and high-power servos. Sealed housing isolates dust and oil to fit flammable & explosive working sites like mines and chemical plants.
Wide Temperature Working Compatibility
Core parts go through high-temperature tempering treatment, operating stably between -20℃ and 100℃. Lubricant hardly solidifies in low temperature outdoor sites or high-heat forging workshops.
Integrated Anti-rotation Safety Assembly
Pre-installed anti-rotation limit kit prevents screw spinning during lifting, cutting eccentric abrasion under heavy load. Vertical lifting accuracy is maintained without extra guiding fixtures.
Customizable Long Stroke Without Vibration
Thickened screw provides strong rigidity. Max 1000mm stroke is available without external guides, with tiny deflection and no shaking during long-distance lifting for large leveling platforms.
Q: What preservation protection should be done for SWL 35T that remains stationary for a long time after shutdown?
A: Coat the screw with anti-rust grease, retract the dust cover and wrap the motor input end for waterproofing. If stored for more than 3 months, refill worm gear lubricant and conduct no-load test run before reuse.
Q:Can SWL 35T withstand instantaneous impact overload? What is the short-term overload limit?
A:Only instantaneous impact load of 1.2 times rated load is permitted, long-term overload is strictly forbidden. Continuous load over 42 tons will cause worm tooth breakage and plastic bending deformation of the screw.
Q:Will different screw lengths of linked SWL 35T units affect synchronous lifting performance?
A:Different screw lengths will lead to lifting height difference. Units in synchronous groups shall adopt unified stroke specifications; independent servo compensation system is required if strokes are inconsistent to eliminate height errors.
