Ridewell has announced the expansion of its RAR-240 series of trailer air-ride suspensions. Now available for order are yoke-mount suspensions designed specifically for use on Ridewell-brand axles with Wabco PAN 22 air-disc brakes. The new suspensions can also be used with IMT’s axles with Wabco Pan 22, 19, or 17 disc brakes, or Haldex discs. Two new designs are available for order:
The yoke trailing-arm beam allows the brake actuator to be placed under the tail, the benefit being that no modifications to the trailer frame beyond those typically done for a standard RAR-240 yoke suspension are required. Also, no change to the normal frame transition geometry is required. Compatible only with Wabco PAN 22 or Haldex ADB.
The RAR-240 has 25,000-lb capacity and a ride height range from 8.0 to 9.5 in. When brake-actuator ground clearance and protection are critical, the newly designed yoke trailing arm below has a ‘banana beam’ that allows the brake actuator to be tucked between the beam and trailer frame. This design requires a more ‘squared-off’ frame transition to allow clearance for the actuator.
