When selecting and using European style wire rope electric hoists, systematic considerations should be made from five core dimensions: brand and quality, performance and parameters, accessories and safety, usage environment and operating standards, and maintenance and upkeep. The specific analysis is as follows:

1、 Brand and Quality: Choose well-known manufacturers to ensure after-sales support

Brand reputation: Priority should be given to well-known brands in the industry such as Kunfeng Heavy Industry. These manufacturers usually have stricter quality control systems and more complete after-sales service networks, which can reduce equipment failure rates and maintenance costs.

Quality certification: Confirm whether the product has passed international quality certifications such as ISO and CE, which are important guarantees for equipment safety and reliability.

2、 Performance and Parameters: Match operating requirements to avoid excessive or insufficient performance

Lifting capacity and lifting height: Choose the appropriate lifting capacity (such as 0.3-80 tons) and lifting height (such as 3-30 meters) according to actual operational needs to avoid equipment overload or resource waste caused by parameter mismatch.

Operating speed: Choose single speed, dual speed, or variable frequency speed regulation models according to job efficiency requirements. Variable frequency speed regulation can achieve more accurate speed control and adapt to different load requirements.

Power parameters: Confirm that the equipment voltage (such as 380V three-phase AC) matches the on-site power supply to avoid equipment damage or abnormal operation caused by voltage mismatch.

3、 Accessories and Safety: The selection of core components is crucial, and safety devices are indispensable

Selection of Steel Wire Rope:

Material and Structure: Priority should be given to wire contact, interactive twisting, and hemp core galvanized steel wire rope (such as 6X36WS-FC-1770), which has higher wear resistance and compression resistance, and is suitable for high-frequency and heavy-duty operations.

Diameter and breaking force: Calculate the required wire rope diameter and minimum breaking force based on the lifting capacity and safety factor (such as n=5.6 under M6 working level) to ensure safety reserve.

Length design: Consider the lifting height, length of the fixing ring and safety ring to avoid the steel wire rope being too short to operate or too long to cause entanglement.

Roll design:

Rope groove parameters: Select the rope groove radius and spacing based on the diameter of the steel wire rope (such as a rope groove radius of 7mm and spacing of 15mm) to ensure that the steel wire rope is arranged neatly and reduce wear.

Diameter and length: Design the diameter and length of the drum based on the lifting height and rope diameter ratio (such as 20:1) to avoid excessive winding layers of the steel wire rope due to the drum being too small, which increases the risk of wear.

Selection of rope guide: Select the corresponding rope guide according to the rotation direction of the drum (such as a right-handed drum with a right-handed rope guide), to ensure smooth retraction of the steel wire rope and prevent jumping.

Safety device:

Lifting height limiter: installed at one end of the drum, calculates the load height by measuring the number of rotations of the drum, and automatically stops the motor when it reaches the upper limit position to prevent over winding.

Dual safety control: equipped with two independent safety control devices (such as encoders) to avoid safety accidents caused by the failure of a single device.

4、 Operating environment and standards: Adapt to working conditions and standardize operating procedures

Environmental adaptability:

Temperature and humidity: The equipment is usually suitable for environments with temperatures ranging from -20 ℃ to 40 ℃ and relative humidity of ≤ 85%. Avoid working in high temperature, high humidity, or corrosive media.

Explosion proof requirements: If the workplace contains flammable and explosive materials, an explosion-proof electric hoist should be selected to ensure safety.

Operating standards:

Overloading is strictly prohibited: Before lifting, confirm that the load weight does not exceed the rated value to avoid wire rope breakage or structural deformation.

Prohibit inclined pulling and lifting: strictly follow the "eleven no lifting" principle to prevent equipment from overturning or steel wire rope from falling out of the groove.

Specialized personnel operation: Designate specialized personnel to operate the equipment, and the operators must be familiar with the operating procedures to avoid accidents caused by misoperation.

5、 Maintenance and upkeep: Regular inspection and maintenance to extend equipment lifespan

Daily inspection:

Wire rope: Check for broken wires, deformation, or wear. If the number of broken wires exceeds 10% of the total or radial wear reaches 40% within a twist, it needs to be replaced immediately.

Hook and limiter: Check whether the hook is intact, whether the limiter is sensitive and reliable, and ensure the safe operation of the equipment.

Regular maintenance:

Lubrication and maintenance: Regularly add lubricating grease to steel wire ropes, drums, bearings and other components to reduce wear and extend service life.

Structural component fastening: Check and tighten all structural component bolts to prevent noise or loosening caused by vibration.

Fault handling: When a fault is detected, stop the machine for maintenance in a timely manner, record the fault symptoms and handling process, and provide reference for subsequent maintenance.
