4 Ton Bridge Crane

1. Product Introduction:

 

The material selection of the main structural parts of 4 ton bridge crane should take into account the importance of the structure under the predetermined working environment, load characteristics, stress state, connection mode, working environment temperature, corrosion, wear, impact, fatigue, brittle aging, welding performance and steel thickness and other factors.

 

Our 4 ton bridge crane structural parts are made of killed steel, the mechanical properties are not less than GB/T 700-2006 "Carbon structural steel" requirements of Q235 or GB/T 699-2015 "high-quality carbon structural steel" requirements of 20 steel.

3. Maintenance of wire rope before installation of 4 ton bridge crane:

 

Before installing the rope, it is a good idea to inspect the rope and its certificate upon receipt to ensure that the rope matches what was ordered.

 

The minimum breaking force for installing the wire rope shall not be lower than the value specified by the crane manufacturer.

 

The diameter of the new rope should be measured and the value (dm) recorded on the straight section without tension on the rope.

 

If the wire rope has been stored for a period of time during which corrosion may occur, it may be more advantageous to carry out a visual inspection and MRT.

 

Check the condition of all pulleys and drum grooves to ensure that they can accommodate the dimensions of the new rope, do not contain any irregularities (such as ripples), and have enough remaining thickness to safely support the rope.

 

The pulley groove diameter should be between 5% and 10% larger than the nominal diameter of the wire rope. For best performance, the groove diameter should be at least 1% larger than the actual diameter of the new rope.

 

4. Applicable Environment:

 

4 ton bridge crane is widely used in workshops, factories, warehouses, stockyards, industrial and mining enterprises, iron and steel chemicals, railway transportation, ports and other occasions to lift goods.

 

This type of overhead crane is specially created to cater to a broad range of material-handling needs, and it is widely used in various industries, including construction, manufacturing, and mining.

 

5. Transportation:

6.Advantage of 4 ton bridge crane:

 

Price concessions: Because of its simple structure, there are only three operating mechanisms: crane operating mechanism, trolley operating mechanism, lifting operating mechanism, coupled with the continuous upgrading of the electrical component design and its stable performance has become stronger, so the price is also very favorable.

 

Stable performance: Now the high-configuration frequency conversion single beam crane is now the new favorite on the market, its smooth operation, the overall convenience, low failure rate, easy maintenance, more energy saving, operation.

 

Strong adaptability to the environment: as long as the plant can set up ox legs. Can set up a single beam crane, even under the eaves of the roof beam drilling can also install a single beam crane, some space. It is small, and the dust is very large, can be said to be erected and installed. Its difficulty, only the installation of a single beam crane can be used.
