7.5 Ton Bridge Crane

Dejun Crane 7.5 ton bridge crane

Common 7.5 Ton Bridge Cranes are composed of mechanical parts, metal structures, electrical equipment, etc. The mechanical part includes the lifting mechanism, trolley operating mechanism, and cart operating mechanism; the metal structure includes the main beam, end beam, driver's cab, etc.; the electrical equipment includes motors, control appliances, etc.

 

How to operate the crane correctly to ensure construction safety?

 

A crane is a mechanical equipment used to carry and lift heavy objects. It is widely used in construction sites, docks, mines and other places. Correct operation of the crane is crucial to construction safety. The following are some basic points and precautions for operating the crane to ensure construction safety.

 

Before operating a crane, you must be familiar with the structure and working principles of the crane and undergo relevant training and qualifications. Untrained personnel are not allowed to operate the crane.

 

Before operating, the crane must be inspected and maintained to ensure it is in normal working order. This includes checking the working conditions of various parts such as wire ropes, hydraulic systems, and electrical systems. If any abnormalities are found, they must be repaired and replaced in time.

 

Before operating a crane, the job site must be assessed and prepared. This includes assessing the weight, shape and size of the lifted object, selecting the appropriate crane for the job, and clearing the work area to ensure it is clear of obstructions and personnel.

 

During crane operation, the operation manual and safety regulations must be strictly followed. The operator must clearly understand the functions of each control device of the crane and use them correctly.

 

When operating a crane, the designated signals and gestures must be strictly followed. The 7.5 Ton Bridge Crane signalman must clearly understand the crane's signaling system and gestures, and cooperate with the operator tacitly.

 

When operating a crane, the operator must ensure that there are no people or obstacles around. Cranes will produce large swings and vibrations when working, and a safe distance must be maintained around them to prevent accidents.

 

When operating a crane, you must ensure that heavy objects are lifted securely and that correct lifting gear and safety devices are used. Spreaders must meet specified standards and undergo regular inspection and maintenance to ensure their reliability and safety.

 

During crane operation, safety inspections and maintenance must be carried out regularly. This includes checking the mechanical components, transmission and braking systems of the crane to ensure they are working properly.

 

When operating a crane, relevant safety regulations and operating instructions must be followed. Follow correct operating procedures and do not change operating methods and working methods without authorization.

During crane operation, you must remain alert and focused at all times, and pay attention to the surrounding environment and working conditions. If any abnormality is discovered, the operation must be stopped immediately and corresponding emergency measures must be taken.

The use and classification of contact slip wires on electric single-girder cranes

 

For an electric single-girder crane, its operation cannot be separated from the application of any accessory. Take the contact slip wire as an example. Without its current transmission, it would be difficult for the equipment to operate. Since the slip wires used in different situations are different, today we will introduce in detail the use and classification of slip wires on electric single-girder cranes.

 

Electric single beam crane

1. Unipolar safety contact slip line

The single-pole energy-saving combined contact line is a very widely used bridge crane contact line on the market. The conductor material is professional conductive aluminum or copper, among which aluminum sliding conductors have a high market share. Its products have good electrical conductivity, high cost performance, safety and reliability. The combined design is convenient for installation and maintenance. It has a wide range of applications and can be used in various indoor and outdoor environments. The current range is available from 200A-2000A, which can meet the product needs of different equipment.

2. Tubular multi-pole safety contact slip line

The tubular safety contact line has conductors embedded in a polyvinyl chloride shell. It is easy to install. It uses red copper as the conductor of the bridge crane contact line. It has good electrical conductivity, but is limited by the inner groove of the shell. It is mostly suitable for mobile devices with low power. .

3. High temperature rigid body contact slip line

The high-temperature rigid body crane contact slide line is composed of a copper conductor and a steel structural frame or aluminum profile. It has high mechanical strength and good stiffness, and can withstand large-intensity impact currents. It uses copper as the conductor and can carry more than 3000A of current. Rigid body bridge crane The contact slip wire is not protected by a shell, has a large heat dissipation area, low temperature rise, and long service life. Due to its special material, it can be used in high temperature, high pressure, high humidity, strong corrosion, and dusty environments, such as steelmaking, metallurgy, chemical industry, docks and other industries.
