Material Handling Transfer Solutions in High Temperature Environment

In metallurgy, casting, glass manufacturing, and other high-temperature operating scenarios, material handling equipment faces a harsh environmental test. When the ambient temperature exceeds 40℃, the performance of ordinary motorized transfer trolley will be greatly reduced, and even cause safety accidents. How to make motorized transfer trolley run stably in high high-temperature environment has become a problem to be solved in industrial production.

Challenges of Motorized Transfer Trolley in High Temperature

High temperature accelerates the aging of electrical components, reduces the insulation performance, and leads to motor overheating, controller malfunction, and other frequent failures. At the same time, high temperature environment, tyres and metal parts of the physical properties will also change, such as rubber tyres softening, wear and tear, steel strength decline, directly affecting the stability and safety of the equipment. In addition, high temperature will also affect the viscosity of the hydraulic system, resulting in reduced transmission efficiency, and even lead to leakage problems, all of which pose a serious threat to the high-temperature environment of the material handling operations!

Selection of Motorized Transfer Trolley for High Temperature

Basic Performance

• 15%-20% safety redundancy should be reserved for the load capacity of electric transfer trolley under high high-temperature environment. For example, the conventional 2 ton model should choose 2.5 ton configuration under high-temperature working conditions to avoid long-term overload operation of the motor.
• In terms of travelling speed, it is necessary to maintain the efficiency of not less than 80% of the ambient temperature environment, and at the same time, it has the ability to start with 15% gradient.
• Track laying requirements are more stringent, the ground flatness error should be controlled at ≤3mm/m, through high-precision construction to reduce transfer trolley bumps and reduce component loss.

High Temperature Resistant Materials

• Adopts Q355NHD weather-resistant steel for the main structure, whose yield strength at 300℃ can still maintain more than 75% of the normal temperature.
• The tyres are made of silicone rubber composite material, which can maintain stable elasticity in 120℃ environment and reduce the wear rate by 40% compared with ordinary rubber tyres.
• Nano-ceramic heat-insulating coating is sprayed on the surface of key components,  effectively blocking the external heat radiation.

Power System

• Electric transfer trolley needs to choose an effective DC motor and controller to provide stable power output and ensure smooth operation even in high-temperature environments.
• The transmission system adopts straight gears with hardened gear surface structure, which improves the transmission efficiency to more than 95%, and with the forced lubrication system, the gear temperature is controlled within 100℃.

Protection System Of Transfer Trolley for High Temperature

• Heat Insulation Protection

The composite heat insulation layer of ceramic fibre board and aluminium silicate fibre mat is laid on the table surface of transfer trolley, which can reduce the ambient temperature of the electrical components under the table surface.

Battery box, cable trunks, and other critical areas are wrapped with removable rock wool insulation sleeve, combined with silicone rubber sealing tape to form a fully enclosed heat insulation space, preventing high temperature intrusion.

• Intelligent Heat Dissipation System

Temperature-controlled cooling fans are installed near the motor, controller, and other heat-generating parts, combined with heat sinks to increase the heat dissipation area. The hydraulic system adopts a heat exchanger to maintain the oil temperature in the optimal working range by circulating coolant.

• Safety Protection Mechanisms

The braking system is equipped with double devices. The limit switches are equipped with high-temperature-resistant proximity sensors, ensuring accurate positioning in high-temperature environments. Fluorescent high-temperature-resistant warning signs are installed on the body of heavy load transfer cart to remind the operator to keep a safe distance.

Maintenance System of Electric Trolley for High Temperature

• Daily Maintenance

Tyre air pressure, braking system effectiveness, and cooling fan operation need to be checked before daily operation. Clean the surface of the equipment after each shift, focusing on removing dust and oil on the surface of the motor heat sink and hydraulic oil cooler to ensure smooth heat dissipation.

• Professional Maintenance

Perform in-depth maintenance every 500 hours, including motor insulation test, controller circuit board dust removal, hydraulic system fluid replacement and other items. Establish a standardised maintenance process for common faults in high-temperature environments to ensure maintenance efficiency and safety.

In the high temperature industrial environment, the reliable operation of electric transfer trolley is directly related to the production efficiency and safety. Through scientific selection and configuration, perfect protection design, intelligent control system, standardised maintenance, and efficient emergency management, it provides a solid guarantee for material handling operations under high temperature working conditions.
