Multiquip EM25610 Swivel Jack - OEM Replacement Part for Concrete Pump Trailers

The swivel jack provides critical support and stabilization for trailer-mounted concrete pumps during setup, operation, and towing transport. This heavy-duty jack assembly allows operators to safely level and support the trailer tongue weight when disconnected from the towing vehicle, and can be raised to a height where it will not interfere with the road during transport. The swivel design enables smooth rotation and extension through a crank or handle mechanism operated clockwise to transfer tongue weight from the hitch to the jack foot.

Before extending the jackstand, always verify the ground surface below the jack foot will adequately support the trailer tongue load. Pivot points and sliding surfaces should be lightly oiled with SAE 30W motor oil to prevent rust and ensure proper operation of the latching mechanism. Inspect regularly for wear indicators including flat spots, deformations, pitting, or corrosion—any bent or broken components must be replaced immediately to prevent system failure.
