{"product_id":"atlas-rj8a-8-000-lb-air-hydraulic-rolling-bridge-jack","title":"Atlas RJ8A 8,000 lb Air\/Hydraulic Rolling Bridge Jack","description":"\u003cp\u003eThe Atlas RJ8A rolling bridge jack delivers 8,000 lbs. of lifting capacity for four-post and scissor lifts, allowing you to raise a vehicle’s wheels off the runways for tire, brake, suspension, and driveline service. Its adjustable rail supports accommodate runway spacing from 36\" to 56-1\/2\", making it compatible with a wide range of lift styles and brands. Before ordering, confirm that your lift’s runway spacing falls within this range. Operation requires an external shop air supply at 70–115 PSI, which is not included.\u003cbr\u003eThe RJ8A uses an air-over-hydraulic system and telescoping arms that extend across the runways. Its roller system lets you move the jack along the lift to position it beneath the area being serviced, while the scissor mechanism keeps the lifting pads level as the vehicle rises. Multiple mechanical safety-lock positions support the load once engaged, allowing hydraulic pressure to be released during service. The included four-piece truck adapter set—two 2.5\" adapters and two 5\" adapters—adds height for reaching lifting points on pickups and larger trucks.\u003cbr\u003eThis bridge jack is a practical addition for home garages, professional repair shops, and service facilities that need to perform wheel-free maintenance using an existing four-post or scissor lift. Its adjustable supports offer flexibility across compatible lift configurations, while the compact, low-profile frame makes positioning and storage easier. A powder-coated finish helps protect the frame in a working shop environment.\u003c\/p\u003e\n\u003ch3 data-pm-slice=\"1 5 []\"\u003e\u003cspan\u003eFeatures\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul data-spread=\"false\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003e8,000 lb Lifting Capacity:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Designed for lifting vehicles off four-post and scissor lift runways for wheel, brake, suspension, and undercarriage service.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eAir\/Hydraulic Operation:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Runs on \u003c\/span\u003e\u003cstrong\u003e\u003cspan\u003e70–115 PSI\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e shop air.
