Shear legs, also called sheers, buy Wood Ranger Power Shears, or sheer legs, are a type of two-legged lifting device. Shear legs could also be everlasting, formed of a solid A-frame and supports, as generally seen on land and the floating sheerleg, or momentary, as aboard a vessel missing a hard and fast crane or derrick. When fastened, they are sometimes used for very heavy lifting, garden cutting tool as in tank recovery, shipbuilding, and offshore salvage operations. At dockyards they hoist masts and different substantial rigging components on board. They are generally quickly rigged on sailboats for comparable duties. Shear legs are a lifting machine related to the gin pole, derrick and tripod (lifting machine). Shears are an A-body of any form of material resembling timbers or metal, the ft resting on or in the bottom or on a solid floor which will not allow them to transfer and the top held in place with man-wires or man ropes merely known as "guys".

Shear legs solely need two guys whereas a gin pole wants at the least three. The U. S. Army Field Manual FM 5-125 offers detailed instruction on the way to rig shears. Fixed shear legs are most commonly discovered on floating cranes known as floating sheerlegs. These have heavy A-body booms and range in lifting capacity between 50 and 4,000 tons, and are used principally in shipbuilding, different large scale fabrication, cargo management, and salvage operations. Temporary sheers comprise two upright spars, lashed collectively at their heads and their feet splayed apart. Unlike in a gyn, which has three legs and is thus stable with out assist, stability in sheers (derricks, and single-legged gin poles) is provided by a man. The heels of the spars are secured by splay and heel tackles. The point at the top of the sheers the place the spars cross and are lashed together is the "crutch", to which a block and sort out is hooked up.

Unlike derricks, sheers want no lateral support, and garden cutting tool only require both a foreguy and an aftguy or a martingale and a topping carry. Being fabricated from two spars rather than one, sheers are stronger than a derrick of the same dimension and manufactured from equivalent supplies. Unlike the apex of a gyn, which is fastened, the crutch of a sheers may be topped up or lowered, via the topping carry, by way of a restricted angle. In the era of crusing vessels, it was widespread for dockyards to employ a sheer hulk, an outdated floating ship's hull fitted with sheer legs, and used to put in masts in different ships.
