What are cranes, and what do they do?

Essentially, cranes are machines with hydraulic arms that can lift and move loads of enormous size and weighing multiple tons. Although cranes and forklifts serve similar functions, cranes can typically maneuver larger and heavier workloads, though they often lack forklifts’ maneuverability.

What some different types of cranes?

An overhead bridge crane consists of two overhead runways built into the building’s support structure, connected by a single- or double-beam configuration called a bridge. The bridge is supported on either end by an end truck, which rides on wheels along a runway or beam, allowing it to move up and down the bay.

An overhead bridge crane can be configured in a single- or double-girder design. In simple terms, a bridge girder, or beam, is the support structure that allows the trolley and hoist to move from side-to-side along the bridge. The trolley precisely positions the hoist prior to raising or lowering a load. Double-girder cranes offer greater weight-bearing capacity but with more complexity and at higher cost.

A gantry crane is similar to a bridge crane, but instead of moving on suspended runways, the crane uses legs to support the bridge, trolley, and hoist. These legs travel on rails that are embedded in or rest on top of the floor or ground structure. A gantry crane is ideal when you require a lightweight and quick knockdown crane for applications that require portability and corrosion resistance. They are also useful when there is a reason not to incorporate an overhead runway system; they’re best for outdoor applications where full beams and columns can’t be installed, or they can be used below an existing bridge crane system. Gantry cranes are commonly found in shipyards, railyards, particular construction sites, or in places like steel mills, where overhead room may be an issue.

A jib crane’s design is simpler than that of the overhead bridge or gantry cranes, yet its workload may reach fifteen tons. Jib cranes can be freestanding, mast-type, or wall-mounted, and articulated jib cranes have multiple swiveling arms to provide maximum versatility.

Nowadays, most industrial cranes are electrically operated. Smaller and older models can be manually operated by means of a chain.

Who should operate cranes?

Moving heavy loads involves significant risks to workplace personnel, equipment, and materials. Dropping heavy materials, lifting workloads beyond the crane’s capacity, or colliding with power lines or other objects can all be deadly. Cranes and the chains used to attach, hoist, and move the loads must be inspected regularly, and workers who operate overhead cranes should be well familiar with the particular crane or cranes being used.

What are some of the best-known crane manufacturers?

If you want to buy a second-hand crane, you should choose one from a respected, well established manufacturer. APT International offers a wide range of cranes from ABUS, DEMAG, MUNCK, TIMMERS, KONE, FIMEC, COMETE, DALMEC, DEMAN + BRUN, and other companies.
