The key components of the crane

A crane is a material handling equipment used to facilitate the movement of large or heavy materials around industrial and commercial construction sites. Although they have a variety of designs and configurations to suit different applications, they usually consist of the same four basic components. Each of these components has different functions. When combined with the functions of other components, the crane component can raise and position the load as,What are the key components of a crane?

Below, we have a more comprehensive summary of each of the four key crane components.
Parts of the crane.
The crane consists of four key components:

  1. Hook up.
    The hook element of the hook and hoist crane is the part that holds or carries the load and is connected to the lifting element. Due to its function, it will experience a lot of wear during operation and become one of the parts that need to be replaced regularly.
  2. Hoist.
    The lifting elements of the crane provide vertical lifting power. Its lifting capacity is affected by its design and structure. For example, the lifting weight of the chain hoist is ≤5 tons, and the lifting weight of the rope hoist is ≥5 tons. Similarly, manual hoists are suitable for lighter loads, and electric hoists are suitable for heavier loads.
    Some cranes have a main hoist and an auxiliary hoist. The former is used to handle heavier loads at a slower speed, and the latter is used to handle lighter loads at a faster speed.
    Third, the trolley.
    The car parts of the trolley running trolley crane provide horizontal movement power. Designed to move crane and hook components along rails or beams, across the top (top-running car) or bottom (bottom-running car) of the bridge assembly.
    Some cranes have bogies. These short-end trucks allow multiple wheels to be placed at each corner of the crane to ensure a more even load distribution.
  3. Bridge
    The bridge parts of the crane are the parts that bear the load and the weight of other crane parts (such as hooks, hoists and cars). It runs over the entire length of the crane system, allowing the car and attached hoists and hooks to move horizontally on the construction site.
    The bridge is composed of large horizontal structural beams (ie girders) supported by terminal trucks. The beam usually has a slight upward vertical bend—that is, camber—to compensate for the deflection caused by the weight of the load and other crane components. Depending on the load requirements, the bridge may have a single-beam or double-beam configuration. The rectangular section of beams, trucks and other components is composed of two rolled steel side plates and a top and bottom plate, which is called box section.
