Overhead cranes can be found in many places from factories, fabrication shops and manufacturing plants to automotive production, shipyards and steel or paper mills. They are used to anchor a lifting hoist and subsequently lift move heavy loads across the fixed runway system high above the factory floor.
When it comes to overhead cranes the wire ropes used are typically for hoisting purposes. They are fitted to the drum of a wire rope hoist, of which there are many types including crab style units. The wire rope will have a bottom block and hook for anchoring loads. The hoist will then wind the rope in and/or out to lift or lower the attached load. Wire ropes may also be utilized for other tasks such as grab ropes or trolley ropes depending on the cranes set up and its intended use.
Overhead crane rope comes in a variety of constructions to suit different hoists and loads. Non-rotating ropes are the safest as they will not spin whilst under load. Compacted rope constructions are also the preferred ropes for hoists and cranes because they are stronger and run more smoothly over the hoists drum.
We can supply a range of rope constructions suitable for this type of application including;
6x31 Compacted - Fibre Core
35x7 Compacted with a fibre core crane rope available in diameters from 10mm up to 28mm. Good Flexibility and ideal for hoist or trolley rope. |
6x31 Compacted Wire Core
The 6x33 compacted with a wire core available in diameters from 10mm to 28mm. High crush resistance. |
6x36 Compacted - Fibre Core
Available in diameters from 32mm to 42mm. Good Flexibility, Ideal hoist or trolley rope |
6x36 Compacted - Wire Core
This wire core rope with a compacted outer layer comes in diameters from30mm to 62mm. High tensile strength and crush resistance.
|
All ropes are galvanized to provide great corrosion resistance.
Full specifications on each rope can be found in the tab above.
Selecting the right rope comes down to the hoist and application. Single-layer drum hoists favour the 24×7 for its simplicity and easier inspection. Multi-layer spooling demands compacted ropes, thus the 35×7 for sheer capacity, the 6×36 where fatigue resistance is important, and the 8×19 where drum size limits rope diameter.
