2. Crane (machine) - Wikipedia

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

   It accounts for the dynamic effects that can increase the load on a crane's structure and components during lifting operations. These effects include: Hoisting acceleration and deceleration of the load, which is a significant factor; Crane movement such as slewing or luffing; Load swinging; Wind forces acting on the crane, the load and the ...

3. Design load - Wikipedia

   en.wikipedia.org/wiki/Design_load

   A crane's rated load is its Safe Working Load (SWL) and the design load (DL) is, (p 90) [1] = The dynamic lift factor for offshore cranes in the range 10 kN < SWL ≤ 2500 kN is not less than =.(p 84) [1] Thus for a crane with a SWL of 2000 kN (~200 tonne) its design load is not less than, = = The minimum breaking load (MBL) for the combined capacity of reeves of a steel wire hoisting rope ...

4. Safe Load Indicator - Wikipedia

   en.wikipedia.org/wiki/Safe_Load_Indicator

   A Safe Load Indicator (SLI) or an Automatic Safe Load Indicator (ASLI) is a device which is installed on mobile or portal cranes to alert the operator if the lift is exceeding the safe operating range of the machinery. [1] In some cases, the device will physically lock the machinery in circumstances it determines to be unsafe.

5. Lifting equipment - Wikipedia

   en.wikipedia.org/wiki/Lifting_equipment

   Lifting equipment can be assigned a Working Load Limit (WLL) in the interests of avoiding failure; Working Load Limit is calculated by dividing the Minimum Breaking Load of the equipment by a safety factor. [5] WLL as a concept is not restricted to lifting, being also relevant for mooring ropes. [6]

6. Telescopic handler - Wikipedia

   en.wikipedia.org/wiki/Telescopic_handler

   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°. The operator is equipped with a load chart which helps him determine whether a given task is possible, taking into account weight, boom angle and height.

7. Counterweight - Wikipedia

   en.wikipedia.org/wiki/Counterweight

   A simple crane. A counterweight is a weight that, by applying an opposite force, provides balance and stability of a mechanical system. [1] The purpose of a counterweight is to make lifting the load faster and more efficient, which saves energy and causes less wear and tear on the lifting machine.

8. Rigging (material handling) - Wikipedia

   en.wikipedia.org/wiki/Rigging_(material_handling)

   Rigging is the equipment such as wire rope, turnbuckles, clevis, jacks used with cranes and other lifting equipment [1] in material handling and structure relocation. Rigging systems commonly include shackles, master links and slings, and lifting bags in underwater lifting.

9. Lampson International - Wikipedia

   en.wikipedia.org/wiki/Lampson_International

   The older three cranes are operated by Lampson International, with the Chinese example the only one to be sold to and operated by an outside company. [ 7 ] [ 8 ] As a crawler crane , the entire machine can carry a load short distances at a job site , increasing its flexibility.
