A jack is a portable device for lifting heavy loads through a short distance.
All jacks (lever and ratchet jacks, screw jacks, and hydraulic
jacks) must have a device that stops them from jacking up too high. Also, the
manufacturer's load limit must be permanently marked in a prominent place on the jack. The
load limit should never be exceeded. A jack should never be used to support a lifted load. Once the load has been lifted, it must immediately be blocked up. Jackstands or suitable blocking should be used to support the load. Dairy or cola crates should not be used to support a load. Use wooden blocking under the base if necessary to make the jack level and secure. If the lift surface is metal, place a 1-inch-thick hardwood block or equivalent between it and the metal jack head to reduce the danger of slippage. |
