The impact of sudden temperature drop on electric chain hoists (electric chain hoists) is multifaceted and can be summarized as follows:
1. Changes in material properties
Increased cold brittleness of metal materials: When the temperature drops sharply, the cold brittleness of metal materials will significantly increase. This means that at low temperatures, the toughness of metal materials decreases and brittle fracture is more likely to occur. For key components of electric chain hoists, such as chains, hooks, etc., this increase in cold brittleness may lead to breakage under heavy loads, thereby causing safety accidents.
2. Decreased lubricant performance
Viscosity increase: Low temperatures can cause the viscosity of lubricants (such as lubricating oil and grease) to increase and their flowability to deteriorate. This can lead to increased friction and wear between the transmission components of the crane, such as chains and gears, and may even cause poor transmission or jamming.
3. Increased failure rate of electrical components
Performance degradation of electrical components: In low-temperature environments, the performance of electrical components may be affected, such as decreased battery life, hardening and cracking of wire insulation layers. All of these may cause malfunctions in the electrical system of the crane, affecting normal use.
4. Ice and slippage phenomena
Ice formation on wheels and brake wheels: In low-temperature freezing weather, the wheels and brake wheels of the crane are prone to ice formation, leading to wheel slippage and decreased brake performance. This will seriously affect the stability and safety of the crane, and may even cause serious accidents such as crane overturning.
5. Changes in load capacity
Reduced load capacity: Although the load capacity of electric chain hoists is mainly affected by their design and manufacturing quality, changes in material properties in low-temperature environments may also indirectly affect their load capacity. Especially at extreme low temperatures, the strength of metal materials may decrease, thereby affecting the overall load capacity of the crane.
In summary, the impact of sudden temperature drops on electric chain hoists is multifaceted, including changes in material properties, decreased lubricant performance, increased electrical component failure rates, icing and slipping phenomena, changes in wire rope performance, and changes in load capacity. Therefore, when using electric chain hoists in low-temperature environments, special attention should be paid to strengthening maintenance and upkeep work to ensure the normal operation and safety of the hoist.
