The impact of high temperature weather on electric hoists is multifaceted, mainly including the following aspects:

1、 The impact on device performance

Softening of metal components:

In high temperature environments, the metal components of electric hoists (such as steel, aluminum, etc.) are prone to softening, resulting in a significant decrease in mechanical strength. For example, when copper metal materials work at temperatures exceeding 200 ℃ for a long time, their mechanical strength will significantly decrease; When the short-term working temperature exceeds 300 ℃, the mechanical strength will also significantly decrease. The mechanical strength of aluminum metal materials is also closely related to temperature. The long-term working temperature should not exceed 90 ℃, and the short-term working temperature should not exceed 120 ℃.

Reduced lubrication effect:

High temperature will reduce the viscosity of lubricating oil, decrease the lubrication effect, and accelerate the wear of the main components of the electric hoist. This may lead to an increase in equipment failure rate and shorten the service life of the equipment.

Overheating of electrical components:

In high temperature environments, the electrical components of electric hoists (such as motors, controllers, etc.) are prone to overheating, leading to performance degradation or even failure. For example, overheating of the motor may cause electromagnetic brake system failure, aging of electrical insulation materials, and brittle cracking of rubber surfaces on electrical system circuits, thereby increasing the likelihood of electrical failures.

Aging of insulation materials:

High temperature can accelerate the aging process of insulation materials in electric hoists, reduce their insulation performance, and even lead to insulation breakdown. This will increase the risk of electrical short circuits and fires in the equipment.

2、 The impact on operators

Operational error:

In hot weather, operators are prone to fatigue and drowsiness, leading to lack of concentration and potentially increasing the risk of operational errors. This may cause accidents such as collisions and tilting of the electric hoist during lifting.

hidden danger:

High temperature environments may also have adverse effects on components such as the hook and wire rope of electric hoists, such as insufficient lubrication and increased wear of the wire rope, thereby increasing safety hazards.

3、 The impact on the work environment

Poor heat dissipation of equipment:

In high temperature environments, the heat dissipation effect of electric hoists will be affected, leading to an increase in the internal temperature of the equipment. If the heat dissipation is poor, it may cause the device to overheat and trigger serious consequences such as fire.

Deterioration of working environment:

High temperature weather may also have adverse effects on the working environment of electric hoists, such as increasing humidity and corrosive gas content in the air. These factors may all cause damage to the electrical system and metal components of the electric hoist.

Response measures

To alleviate the impact of high temperature weather on electric hoists, the following measures can be taken:

Strengthen equipment maintenance:

Regularly inspect and maintain the electric hoist to ensure that the equipment is in good condition. Special attention should be paid to checking the status of key components such as electrical systems, lubrication systems, and insulation materials.

Improving the working environment:

Try to improve the working environment of the electric hoist as much as possible, such as adding ventilation equipment and reducing indoor temperature. This helps to reduce the accumulation of heat and poor heat dissipation inside the device.

Reasonably arrange work time:

In hot weather, the working and resting time of operators should be arranged reasonably to avoid fatigue and drowsiness caused by prolonged continuous operation.

Strengthen safety training:

Regularly provide safety training and education to operators to enhance their safety awareness and operational skills. This helps to reduce the occurrence of operational errors and safety accidents.
