Rotary RJ7100 7,000 lb Rolling Jack for Lift Runways
The Rotary RJ7100 is a heavy-duty rolling jack that enables wheels-free service while a vehicle remains positioned on four-post or scissor runway lifts. Featuring an air-operated scissor mechanism, adjustable runway width from 36 3/4" to 46 1/16", and included rubber pads and adapters, this unit expands service capabilities for brake, suspension, and tire work across professional automotive facilities.
Key Features & Benefits
Air-Operated Scissor Mechanism
The RJ7100 uses a direct air-operated scissor design that raises and lowers smoothly through a shop's standard compressed air supply. The 7,000 lb rated capacity is achieved through precision-engineered scissor linkages that distribute load evenly across the entire lift range.
Traditional rolling jacks require manual pump handles or electric motors, adding operational complexity to routine service work. This air-operated design addresses that challenge by integrating seamlessly with existing shop infrastructure, allowing technicians to operate the jack from any location where compressed air is available.
This enables faster wheels-free service on suspension and brake work, since technicians can raise and lower the jack as needed without stopping to engage manual mechanisms. The smooth operation reduces fatigue and keeps work pace consistent throughout the service day.
Mechanical Locking Latch System
The integrated mechanical latch automatically engages at full rise, securing the jack's lifting platform without requiring continuous air pressure or manual lock activation. This full-rise locking design holds position securely during active service operations on wheels and undercarriage components.
Conventional rolling jacks rely on continuous operator vigilance or electrical solenoid locks that can fail under elevated service loads. This mechanical latch addresses the industry-wide safety challenge by providing passive holding strength that doesn't depend on power supply or operator attention once the vehicle is fully raised.
This eliminates unplanned platform drift and enables safer brake bleeding, suspension removal, and tire service operations. The handle-operated release mechanism provides instant pressure relief when the job is complete, with no delay or mechanical adjustment required.
Adjustable Runway Width Accommodation
The jack's runway width range spans 36 3/4" to 46 1/16" (934 mm to 1,170 mm), enabling installation on multiple four-post and scissor lift configurations without custom adapters. The width adjustment mechanism is integral to the jack frame, maintaining structural rigidity across the entire adjustment range.
Different lift models and facility installations use varying runway spacing, creating a common compatibility problem when purchasing rolling jacks. Shops often need multiple units to cover different lift widths, increasing capital expense and floor space requirements. This design addresses that challenge by accommodating the most common runway configurations in a single unit.
This flexibility reduces inventory requirements and enables the jack to serve multiple lifts across a multi-bay facility. New facility expansions can adopt the same jack model without purchasing additional equipment or worrying about incompatibility with different lift brands or series.
Heavy-Duty Urethane Compression Wheels
Four heavy-duty urethane compression wheels provide smooth rolling across lift runways while accommodating the jack's full 7,000 lb load rating. The urethane material provides gripping traction on painted steel surfaces without marring or damaging lift runway finishes.
Standard rubber wheels or plastic casters degrade quickly under repeated heavy loads and frequent movement across textured lift surfaces. This design addresses shop floor durability challenges by using compression-molded urethane that resists permanent deformation and maintains traction across thousands of positioning cycles.
This improves operator control during positioning, reduces repositioning effort, and extends component life compared to wheels requiring annual replacement. Maintenance costs decrease since urethane wheels don't leave residue marks on runways or require periodic lubrication.
Included Rubber Pads and Adapters
The jack ships with rubber pads in 1 1/2" and 3" sizes, plus adapter blocks and extensions that provide immediate compatibility with a wide range of vehicle lift points. This included accessory set eliminates the need for separate aftermarket purchases and adapts to different vehicle frames and geometries.
Professional shops encounter vehicles with varying suspension heights, frame widths, and lift point configurations. Accessory jacks without comprehensive pad and adapter sets force technicians to improvise contact points or fabricate custom solutions, compromising both safety and positioning accuracy. This design includes the most commonly required pads and adapters as standard equipment.
This reduces setup time for wheels-free service, improves positioning accuracy on different vehicle types, and ensures consistent load distribution across varied lift points. Technicians can move between different job types throughout the day without searching for compatible accessories or waiting for equipment to arrive.
Compact Rolling Design for Professional Facilities
The RJ7100's four rail-engaging wheel assemblies with heavy-duty urethane provide smooth mobility across lift runways in busy service environments. The compact footprint allows the jack to fit efficiently between lift runways without requiring excessive floor space or special positioning procedures.
Rolling jacks with oversized wheels or poor maneuverability create operational friction in multi-bay shops with tight runway spacing. This design addresses the practical challenge of facility constraints by maintaining precise control and smooth rolling across various runway configurations and surface finishes without binding or marring.
This enables quick repositioning between service bays and supports high-volume service operations where technicians move the jack frequently throughout the day. The efficient design reduces operator fatigue and keeps wheels-free service workflows streamlined across different work stations.
