Worm Gear Screw Jack 2.5 TON

2.5 Ton Machine Screw Jack

All metric 2.5 Ton Machine Screw Jacks have a trapezoidal thread form. For loads of 25% to 100% of screw jack capacity, torque requirements are approximately proportional to the load. Efficiency values for standard grease lubricated worm gear box and lifting screw. All screw jacks have grease lubricated gearbox and lead screw as standard. Machine screw jacks can be fitted with a safety nut. In the event of excessive wear on the nut thread the load will be transferred from the standard nut to the safety nut.

2.5 Ton Screw Jack system, with the following characteristics:

Maximum static load capacities: 2.5 ton.

Screw details: Self-locking trapezoidal screw sizes Tr 30x6.

Gear ratios: Two options: high ratio 6:1 and slow ratio 24:1 for different linear speeds.

Stroke length: Custom stroke length, maximum 2000 mm in compression load, 2500 mm in tension load.

Basic designs: Translating screw, keyed screw, and rotating screw.

Mounting: Upright or inverted mounting, available in tension or compression loads.

Thread options: Standard with 1-start thread screw; custom 2-starts threads offer increased travel speed but require a brake or external locking device to hold position.

Screw end fittings: Top plate, clevis end, threaded end, plain end, fork head, and rod end.

Power sources: Manual operation (hand wheel and crank handle), electrically by motor drive, or both combined.

System integration: Can be used individually or combined into synchronized lifting systems using connecting shafts, bevel gearboxes, couplings, motors, gear reducers, limit switches, and pillow blocks.

Custom options: Double clevis screw jack, trunnion mount screw jack, and anti-backlash screw jack.

The materials used for the 2.5 Ton Machine Screw Jack detailed below:

Housing: High-strength Casting Housing, Ductile Iron. Custom options include Stainless Steel 304.

Input Shaft (Worm): C45 Steel with high frequency heat treatment. Custom options include Stainless Steel 304 or 316.

Lifting Screw: C45 Steel as standard. Custom options include Stainless Steel 304 or 316.

Worm Gear / Travelling Nut / Safety Nut: ZQAl9-4 (Casting aluminum bronze) as standard. Custom option is ZCuSn10Pb1 (Casting tin bronze).

Bearing: Anti-friction Ball Thrust Bearings for Worm Gear and Anti-friction Ball Bearings for Input Shaft (worm). Custom option is Stainless Steel 304.

Motor Flange Adapter: High-strength Casting Motor Adapter, Ductile Iron. Custom options include Stainless Steel 304 or 316.

Lubricants: Synthetic Grease, Extreme Pressure EP2 Lithium Grease.

• Power and Performance:Operates at 15W continuous duty (S1), providing low rotational speeds (typically 90300 RPM after reduction) and increased torque compared to non-geared motors.
• Voltage Options:Available in DC (12V, 24V) and AC (110V/220V, 50Hz/60Hz) variants.
• Gearbox Types:Typically uses planetary, spur, or worm gear systems to increase torque density.
• Structure:Often housed in aluminum or hardened steel, frequently featuring a sealed design (IP44, IP54, or IP55) to protect against dust and moisture.
• Features:Often paired with speed controllers, permanent lubrication (grease), ball bearings, and optional encoders for closed-loop control.
