What are the specifications of cranes?
1, bridge crane, which refers to a crane that looks like a bridge. Generally used in indoor warehouses, with large bearing capacity. The common model is LDA 1-20T, which can bear 20T and belongs to electric single-beam crane. Its characteristics are flexibility, convenience and strong bearing capacity.
It is also an electric single beam type, and the LX type 0.5-5t type has weak bearing capacity, but it is compact and easy to use. The LB 1- 10t explosion-proof crane is very reliable and safer to use. LXB 0.5-5t explosion-proof type has the disadvantages of weak bearing capacity, and the advantages of flexibility, convenience and simple operation.
2. Gantry crane. This type of crane has its own characteristics. For example, the common MH 3-20t electric hoist crane is truss type, which is larger and has stronger bearing capacity than the bridge crane. This MH 5-25t electric hoist crane has two types: box beam and truss leg.
L-type 5- 10t electric hoist is suitable for outdoor use, and its operation is relatively simple. MDSG 30/5- 120/5t double-beam crane is a super-large crane, which is often used in pavement construction and reconstruction. The technology of this kind of crane is quite complicated and expensive.
Crane refers to a multi-function lifting machine that vertically lifts and horizontally carries heavy objects within a certain range. Also known as crown block, crane and crane. The main feature of tire crane is the integration of cab and hoisting control room, which evolved from crawler crane.
The crawler and walking bracket of the walking mechanism are changed into chassis with tires, which overcomes the shortcoming that the crawler plate of crawler crane damages the road surface and belongs to material handling machinery. Bridge crane is a kind of lifting equipment installed horizontally above workshops, warehouses and yards for lifting materials.
Because its two ends are located on tall concrete columns or metal supports, it is shaped like a bridge. The bridge of bridge crane runs longitudinally along the tracks laid on the overhead bridges on both sides, which can make full use of the space under the bridge to lift materials without being hindered by ground equipment.
