2. Jib (crane) - Wikipedia

   en.wikipedia.org/wiki/Jib_(crane)

   A jib or jib arm is the horizontal or near-horizontal beam used in many types of crane to support the load clear of the main support. [1] [2] An archaic spelling is gib. [3] Usually jib arms are attached to a vertical mast or tower or sometimes to an inclined boom.

3. Crane (machine) - Wikipedia

   en.wikipedia.org/wiki/Crane_(machine)

   The generally accepted definition of a crane is a machine for lifting and moving heavy objects by means of ropes or cables suspended from a movable arm. As such, a lifting machine that does not use cables, or else provides only vertical and not horizontal movement, cannot strictly be called a 'crane'. Types of crane-like lifting machine include:

4. Level luffing crane - Wikipedia

   en.wikipedia.org/wiki/Level_luffing_crane

   A level-luffing crane is a crane mechanism where the hook remains at the same level while luffing: moving the jib up and down, so as to move the hook inwards and outwards relative to the base. [1] Usually the description is only applied to those with a luffing jib that have some additional mechanism applied to keep the hook level when luffing.

5. Titan (crane) - Wikipedia

   en.wikipedia.org/wiki/Titan_(crane)

   On completion, the crane was handed over to the RAN. [3] Titan ' s cantilever-jib arm could reach 190 feet (58 m) above the surface at maximum extension. [4] The crane could lift up to 150 tonnes (150 long tons; 170 short tons) at an arm radius of 90 feet (27 m), or 125 tonnes (123 long tons; 138 short tons) at 125 feet (38 m). [4]

6. Beardmore Crane - Wikipedia

   en.wikipedia.org/wiki/Beardmore_Crane

   Upon completion, the shorter arm was tested to lift 200 tonnes (200 long tons; 220 short tons) at a radius of 72 feet 2 inches (22.00 m) and the longer arm could lift 50 tonnes (49 long tons; 55 short tons) at a radius of 139 feet 5 inches (42.49 m). [1] Railway tracks running beneath the crane allowed material to be moved from the workshops.

7. Hoist (device) - Wikipedia

8. Telescopic handler - Wikipedia

   en.wikipedia.org/wiki/Telescopic_handler

   A vehicle with a 5,000 lb (2,300 kg) capacity with the boom retracted may be able to safely lift as little as 400 lb (180 kg) with it fully extended at a low boom angle. The same machine with a 5,000 lb (2,300 kg) lift capacity with the boom retracted may be able to support as much as 10,000 lb (4,500 kg) with the boom raised to 70°.

9. Counterweight - Wikipedia

   en.wikipedia.org/wiki/Counterweight

   Crane The tower crane (see picture) is a modern form of balance crane that is fixed to the ground. A horizontal boom is balanced asymmetrically across the top of the tower. The long arm carries the lifting gear. The short arm is called the machinery arm; this holds the motors and electronics to operate the crane, as well as the concrete ...
