Vestil LO-J-BEAM Trailer Stabilizing Jack 40000 Lb

Product Description

The VESTIL MANUFACTURING LO-J-BEAM is a heavy-duty ratchet beam trailer stabilizing jack built for loading dock and freight yard applications. Constructed from high-strength steel with a powder coat safety yellow finish, this jack is designed to prevent semi-trailers from up-ending when disconnected from a tractor during loading and unloading operations. It also prevents landing gear from sinking into soft ground surfaces. A flush-type Zerk fitting allows on-site lubrication of the Acme screw mechanism. The unit ships as a single piece and weighs 182 pounds.

This stabilizing jack is used at commercial loading docks, distribution centers, and freight terminals wherever unattended semi-trailers require support during cargo operations. It is suitable for both concrete and soft-surface dock environments. The unit meets OSHA regulations when used in conjunction with wheel chocks. A reflective collar improves visibility during night or low-light operations. The unique ratchet beam design allows leveling of trailers parked on sloped or uneven ground, making it practical for facilities that cannot guarantee a level dock surface.

Installation Notes

Positioning and setup of trailer stabilizing jacks is typically performed by dock workers or material handling equipment technicians.

Consult applicable OSHA dock safety standards and facility protocols before placing the unit into service.
