Jun 2022
DESCRIPTION
The RAJ-7K-H & RAJ-7K-L Rolling Bridge Jacks are 7,000 lb. capacity pneumatic / hydraulic
operated, scissor-style rolling bridge jacks, designed to be mounted on four post or scissor lift
’s jack
rails, between runways. Both models are capable of lifting the wheels off runways to provide
‘wheels
free
’ service for brake, suspension, tire repairs and maintenance jobs. The universal adjustable roller
body design comes in both high
‘H’ & low ‘L’ mount model configurations for low & high runway jack
rail configurations. The RAJ-7K
’s Roller Body Wheels are designed to ‘track’ on the top edge of the
Jack Rails for smooth rolling operation.
FEATURES
A. Lifting capacity of the RAJ-7K Rolling Jacks are 7,000 lbs. (3,175 kgs).

runways.

between runways. Ensure rollers are centered on top of jack rails & side rollers are adjusted to
side of jack rails.
6. Once jack rollers are properly aligned & centered to top of jack rails, ensure to secure the roller
body
‘slider’ extensions in place by tightening the four hex bolts located at each corner of jack.

hose connections for leaks; add oil and tighten hose connections, if required.
