OTC's Bottle Jacks, Nos. BT12 and BT30, are heavy-duty lifting solutions designed to support a wide range of foreign and domestic vehicles for the trucking and construction industries. Compact and durable, the BT12 offers a 12-ton capacity and the BT30 a 30-ton capacity, with both featuring a forged base cylinder for reliable lifting power whether on the road, in the shop, or at a job site. The jacks' inline design is meant for easy-to-use positioning and lifting, and the chromed pump piston and ram help resist rusting while a built-in extension screw can provide extra height as necessary.
