The LD type electric single-girder crane is an indispensable lifting equipment in the modern industrial field. It is widely used in various industrial sites because of its efficient operating performance and convenient operation. The details of this device and its applications will be discussed in depth below to ensure that people have a comprehensive and specific understanding of this device:
Introduction
Design standards: LD type electric single-girder crane is designed and produced in accordance with GB/T 381 JB/T 1306-2008 standards. The rated lifting capacity of this type of crane is usually between 3 and 10 tons, and the span ranges from 7.5m to 22.5m. Its working level is A3-A4, indicating that it can continue to operate under medium workload.
Main structure: The machine consists of an electric hoist, metal structure, cart operating mechanism, feeder device and electrical device. Its simple structural design not only facilitates operation, but also reduces maintenance costs and failure rates.
Technical features
Main girder design: The LD type electric single-girder crane uses a computer-optimized box girder as the main girder. This structure enables the crane to achieve greater stiffness while having a smaller dead weight, significantly reducing track load and improving overall work efficiency.
Power supply system: This device uses a highly flexible flat cable to supply power to the car and has grounding protection. This power supply method can effectively prevent power failures and ensure operational safety and stable operation of equipment.
Control system: LD type electric single-girder crane can be operated through a flashlight door or remote control. The operator can choose the most appropriate control method according to the actual situation. This flexible control method provides more operational convenience and can adapt to different working environments.
Application areas
Factory production line: LD type electric single-girder crane can be used for material handling, hoisting, assembly and other operations on the factory production line to improve production efficiency and reduce labor intensity.
Warehouse logistics: In warehouses, LD electric single-beam cranes can be used for loading, unloading, stacking, sorting and other operations of goods to improve logistics efficiency and reduce labor costs.
Workshop maintenance: In workshop maintenance work, the LD type electric single-girder crane can be used for equipment disassembly, installation, maintenance and other operations, which is convenient and fast.
Mining: During the mining process, the LD type electric single-girder crane can be used for the transportation and loading of ore to improve mining efficiency.
Construction sites: On construction sites, LD type electric single-girder cranes can be used for transportation, hoisting and other operations of building materials, reducing workers' labor intensity and improving work efficiency.
Port terminal: At the port terminal, the LD electric single-girder crane can be used for cargo loading, unloading, stacking and other operations to improve port operation efficiency.
Power station boiler room: In the power station boiler room, the LD type electric single-girder crane can be used for fuel transportation, hoisting and other operations to ensure the normal operation of the boiler room.
Papermaking and printing industry: In the papermaking and printing industry, the LD type electric single-girder crane can be used for handling, hoisting and other operations of paper, printed matter and other materials to improve production efficiency.
Steel and metallurgical industry: In the steel and metallurgical industry, LD type electric single-girder crane can be used for transportation and hoisting of steel, iron ingots and other materials, reducing labor intensity and improving production efficiency.
Petrochemical industry: In the petrochemical industry, LD type electric single-girder crane can be used for handling, hoisting and other operations of chemical raw materials, petroleum products and other materials to ensure production safety.
Routine maintenance
Maintenance: Regularly manage the key to the power switch box, and the electric hoist needs to be maintained and inspected by a dedicated person. The electrical device and control system must be thoroughly inspected every 200 hours of use to avoid accidents. These routine maintenance measures can greatly extend the service life of equipment and reduce unplanned downtime.
Inspection frequency: Regularly check the tightening of the wire rope drum, rope guide and support bolts. Conduct a comprehensive inspection of the crane's usage every year, especially the wear of wearing parts and transmission parts. If excessive wear is found, replace it immediately. .
