High temperature resistant overhead crane: key equipment in high temperature industry

Table of Contents

Introduction
In high-temperature industrial environments, such as steel smelting, glass manufacturing, cement production and other fields, equipment faces extreme working conditions. These environments are not only high in temperature, but also often accompanied by corrosive gases, dust and other harsh factors, which puts extremely high demands on the performance of cranes. As key equipment in these high-temperature industries, the importance of high-temperature bridge cranes is self-evident. They not only need to maintain stable operation under high temperatures, but also need to have excellent safety performance and durability to ensure the continuity and safety of the production line.

Life of overhead cranes in high temperature environments

1. Direct impact of high temperature on the life of bridge cranes

Aging and wear of parts and components are aggravated

Under high temperature conditions, the parts and components of bridge cranes are prone to aging, such as hydraulic oil is prone to deterioration, and the wear of mechanical components will also be aggravated.
Long-term high temperature exposure may cause the performance of component materials to deteriorate, such as reduced hardness and weakened toughness, which will affect the overall performance and service life of the crane.

Increased risk of electrical system failure

High temperature environment may generate static electricity, which increases the risk of damage and short circuit to the crane's electrical system.
Cables and connectors in the electrical system are easily affected by factors such as heat waves and vibrations, resulting in poor contact or damage, which in turn affects the normal operation of the crane.

Deterioration of hydraulic oil system performance

Under high temperature environment, hydraulic oil is prone to deterioration, such as oxidation, reduced viscosity, etc., which affects the stability and reliability of the hydraulic system.
Deteriorated hydraulic oil may cause problems such as unstable system pressure and leakage, which in turn affects the lifting capacity and safety of the crane.

2. Maintenance measures for overhead cranes in high temperature environments

Strengthen cleaning and maintenance

Regularly clean and maintain mechanical parts, remove dust and oil stains, and keep their surfaces dry.
Clean the power supply to ensure that it is powered normally and prevent electrical system failures caused by static electricity and other reasons.

Regularly check and replace parts

Regularly check the wear and corrosion of mechanical parts, such as axles, brakes and gears, and replace and repair damaged parts in time.
Regularly check the cables, connectors and controllers in the electrical system to ensure their normal operation.

Strengthen lubrication and cooling

Develop a lubrication plan based on the frequency of use and load size to ensure that the lubricant starts to work after heating.
Regularly check the sealing of the oil filling port and the oil outlet, and replace the lubricant.
For parts that need to be cooled, such as motors, ensure that they are well cooled to avoid overheating and damage.

Reasonably arrange the use time

Try to avoid high temperature periods and choose to perform lifting operations in the relatively cool morning and evening.
For cranes that need to operate for a long time in a high temperature environment, appropriate cooling measures should be taken, such as installing awnings, using fans or air conditioners, etc.

Technical features of overhead cranes used in high temperature environments

1. Application of high temperature resistant materials

During the design and manufacturing process of high temperature resistant bridge cranes, high temperature resistant materials such as special alloy steel and ceramic coating are widely used to improve the high temperature resistance of the equipment. These materials can maintain stable physical and chemical properties at high temperatures to prevent the equipment from deforming, melting or failing due to high temperatures.

2. Special cooling system

In order to reduce the temperature of the equipment in high temperature environments, high temperature resistant bridge cranes are usually equipped with special cooling systems. These systems remove the heat generated by the equipment by circulating cooling media (such as water, air, etc.) to ensure that the equipment maintains a stable temperature during long-term high temperature operations.

3. Safety protection measures

High temperature resistant bridge cranes are also specially designed for safety protection. For example, high temperature resistant electrical components and cables are used to prevent electrical failures caused by high temperatures; emergency brake systems and limiters are set to ensure that the equipment can be quickly stopped in an emergency; heat radiation protection devices are used to reduce the damage to operators caused by high temperatures.

4. QDY type overhead crane

Features: QDY type general bridge crane is designed for lifting molten metal in smelting workshops and hot objects (molten non-metallic objects and solid metals with a temperature lower than molten metal) in hot processing workshops such as rolling. The working level of this equipment is A7, and the lifting capacity is less than 75 tons, which complies with the national standards of the People's Republic of China GB 3811, GB/T 14405-1993 and the relevant regulations of the General Administration of Quality Supervision, Inspection and Quarantine.

Scope of application: QDY type general bridge crane is not only suitable for lifting operations in high temperature environments, but also can be used for lifting and loading and unloading in busy places such as machinery manufacturing, metal structure, assembly workshops and warehouses with continuous production.

What other factors should buyers pay attention to?

When purchasing high-temperature resistant bridge cranes, in addition to searching for suppliers, buyers also need to pay attention to the following factors to ensure that the purchased equipment can meet the actual needs of the factory and have a long service life:
