Frequently Asked Questions
What is the primary application of the SWL screw jack gearbox in construction?
The SWL screw jack gearbox is primarily designed for lifting, lowering, and positioning heavy structures in jump form construction systems. It provides synchronized, precise, and stable mechanical lifting for concrete formwork platforms.
Does the SWL screw jack have self-locking capabilities?
Yes, SWL series worm gear screw jacks feature a self-locking function (especially those with larger reduction ratios and trapezoidal screws). This ensures that the heavy load remains securely in position even if the power source is cut off, enhancing safety on construction sites.
How can multiple SWL screw jacks be synchronized?
Multiple SWL screw jacks can be linked mechanically using connecting shafts, couplings, and bevel gearboxes to form a multi-point lifting system. This configuration guarantees perfectly synchronized lifting across all points under varying loads.
What load capacity range does the SWL screw jack support?
The SWL series offers a wide range of load capacities, typically starting from 2.5 tons up to 120 tons or more per single jack, making them highly adaptable to various heavy-duty industrial and construction requirements.
What maintenance is required for SWL screw jacks in construction environments?
Regular lubrication of the lead screw and gear housing is crucial. In dusty construction environments, it is highly recommended to use protective bellows (dust covers) to prevent concrete dust and debris from damaging the screw threads.
