Multiquip EM517113 LS400/LS500 - OEM Concrete Pump Replacement Part

This OEM swivel jack stand assembly provides critical leveling and support for Multiquip concrete pump trailers during operation and while parked. The jack stand allows operators to adjust trailer height to achieve a level position, which is essential for safe pump operation and proper material flow. During transport, the jack stand raises to prevent road interference, then deploys to support the trailer tongue weight when stationary.

The jack stand works in conjunction with the rear pumping jack stands to maintain stability on firm, level ground. Proper deployment prevents tipping and ensures the trailer maintains correct operating angles. When parked, this swivel jack should be used alongside support blocks placed underneath the trailer bumper for maximum stability. The jack assembly mounts to the trailer tongue and must be secured tightly with all fasteners visibly solid against the trailer frame.

Compatible with the following Multiquip concrete pump models:

• LS450
• LS600P
