Norco Two-Stage Telescopic Floor Jack, with a capacity of 50 tons on the first ram and 25 tons on the second, features a lift height from 8.7" to 16.6" and requires 120-175 PSI of air for its air/hydraulic operation. Designed for heavy-duty truck, rail, bus, agriculture, and construction equipment applications, this jack features a double-acting pump to raise the ram more quickly to the load and and a vacuum-operated ram retraction system to eliminate manual lowering of the jack. A 5'-long "T" handle helps in positioning the jack under vehicles with a low overhang, and a handle-locking lever secures the jack's handle in the vertical, 45, or horizontal position. This unit also features a safety overload system to prevent cylinder damage, an integrated filter to protect the air motor, and a safety button at the top of the handle that can be pushed to immediately stop the jack operation in case of emergency. A suspension-loaded axle prevents wheel damage, and the jack's two rams come with a rust-inhibitive coating. This model jack also includes a removable 4-3/8" diameter saddle, as well as 2-9/16" and 5-7/8" extensions and an extension holder.
