The Rotary R5100HD Pro is a towerless commercial truck and trailer alignment system that adds alignment revenue to a heavy-duty shop without giving up a bay. Position the console on the floor, on a lift, or over a pit — the mobile PC tablet lets a technician monitor and control the whole process from anywhere in the bay, and patented no-run-out clamps skip rolling compensation to save 15–20 minutes of setup per vehicle.

Key features

• Towerless & portable — no dedicated alignment bay; measure on the floor, a lift, or a pit
• Mobile PC tablet operation with three fixed magnets to mount it on the lift or the vehicle chassis — fewer trips to a console means quicker alignments
• 6-CCD infrared sensors across 4 supplied measuring heads; infrared transmission makes it a multi-axle-ready system
• Multi-axle ready — measures up to 8 axles as a trailer aligner
• Patented no-run-out fast tire clamps — reference wheel center without raising the wheel, saving 15–20 minutes per setup
• Double inclinometer allows caster adjustment without steering
• LED repeaters on the sensors show when an angle is in spec; LED sensors read at up to 59 ft
• Wireless Bluetooth between the front heads and control unit — no interruptions at any lift height
