LD type electric single beam bridge crane

The new LD type electric single beam bridge crane refers to a crane in which the electric hoist trolley runs on the lower flange of the main beam, and the electric hoist is arranged below the main beam. There are two types of operating rooms, open and closed, which can be installed on the left or right side according to the actual situation. The entrance direction has two types: side and section, to meet the needs of users in various situations.

Scope of application of single beam bridge crane

Widely used for lifting goods in different occasions such as factories, warehouses, and material yards, it is prohibited to use it in environments with flammable, explosive, and corrosive media.

There are two forms of operation: ground and control room. There are two types of control rooms: open and closed. They can be installed on the left or right side according to the actual situation. The entrance direction has two types: side and end, to meet the needs of users in various situations.

Single beam overhead cranes are widely used in workshops, warehouses, and material yards in industries such as mechanical manufacturing, metallurgy, petroleum, petrochemicals, ports, railways, civil aviation, power plants, papermaking, building materials, and electronics. It has the advantages of compact external dimensions, low building clearance height, light weight, and low wheel pressure.

Working mode of single beam bridge crane

It is installed on the crane beams on both sides of the delivery room, and the whole machine can travel horizontally on the tracks laid on the crane beams. The lifting trolley travels along the trolley tracks (horizontally). The hook performs lifting and lowering movements, that is, in conjunction with CD1 type (or MD1)The electric hoist is used to complete the lifting and translation of heavy objects, which are difficult for people to achieve.

Characteristics of single beam bridge crane mechanism

Characteristics of LD type electric single beam bridge crane: simple structure, light weight, low load on the factory building, small building height, and low power consumption. The main beam and end beam are connected by bolts for easy disassembly, transportation, and storage. It is convenient to replenish spare parts, has low wheel pressure, and good processability. It is suitable for automatic welding and assembly line processing, with fast installation and easy maintenance. The disadvantage is that the lifting capacity is not large.

LD type electric single beam bridge craneOperation precautions

1. Heavy objects should be able to move in the up, down, left, right, front, and back directions, and can also move simultaneously in the three-dimensional direction. Terminal protection should be set for all five directions except for downward movement.

2. There should be a stable braking device so that even in the event of a power outage, heavy objects will not fall due to their own weight.

3. There should be a large speed range, and when starting to move from a stationary state, the acceleration should gradually increase from low speed, and the acceleration should not be too large.

4. Equipped with short-term overload protection measures, overcurrent relays are generally used as circuit overload protection.

5. Equipped with voltage loss protection and safety measures.
