Catalogue specifications

Selected entries from the supplied QL catalogue table. Larger catalogue entries are not adopted here without a confirmed current drawing and configuration.

Match the mechanism to the procurement requirement

A search for a screw jack can refer to a portable manual jack, a screw actuator or another positioning component. This page concerns the upright manual mechanical family shown in the JILI catalogue. It does not claim compatibility with motor-driven lifting systems, construction shoring systems or precision actuators.

Specify more than a capacity number

Give the required load, initial clearance, travel, contact arrangement and available base area. For replacement purchases, send the existing nameplate and dimensions instead of assuming that similar-looking screw jacks interchange. Ask for the drawing, operating instructions and identification details with the offer. Conditions for lifting and supporting a load must be checked for the actual equipment and application.

Wholesale enquiries and order confirmation

For distributor or project orders, send the quantity by model, destination country and required delivery date. We will confirm the current configuration, packing dimensions, gross weight, documentation, sample arrangements and production lead time in the quotation. Catalogue data is a selection reference; the agreed specification and instructions supplied with the equipment govern the delivered unit. No inventory, delivery date or certification is implied by a catalogue listing.
