When using European style wire rope electric hoists, strict control is required from five aspects: operating standards, safety protection, environmental adaptation, maintenance, and compliance management to ensure efficient and safe operation of the equipment. The following are specific precautions:

1、 Operation standard: Strictly follow the process to avoid misoperation

Load limit

Overloading is strictly prohibited: Before lifting, it is necessary to confirm that the load weight does not exceed the rated value (such as using a 5-ton electric hoist to lift goods weighing more than 5 tons). Overloading can cause wire rope breakage, motor burnout, or structural deformation.

Uniform load: Avoid biased or impact loads, prevent equipment overturning or wire rope derailment. For example, when lifting long materials, a balance beam or double hook lifting is required.

Lifting and operation control

Smooth lifting: When starting and stopping, operate slowly to avoid sudden acceleration or deceleration that may cause the load to shake. For example, in the hoisting of precision instruments, millimeter level control needs to be achieved through variable frequency speed regulation.

Prohibition of inclined pulling and lifting: Strictly follow the "eleven no lifting" principle (such as not lifting due to unclear signals, overload, safety device failure, etc.), as inclined pulling can lead to increased wear and even detachment of the steel wire rope.

Use of limiters

Upper limit: When the hook rises close to the top of the drum, the limiter should automatically cut off the power supply of the lifting motor to prevent over winding. Operators are not allowed to intentionally shield or adjust limiters.

Lower limit: Some models are equipped with lower limit to prevent wire rope relaxation or equipment damage caused by hook contact with the ground.

2、 Security protection: multiple measures to ensure the safety of personnel and equipment

Personal Protective Equipment (PPE)

Operators are required to wear protective equipment such as safety helmets, anti slip shoes, gloves, etc. When working at heights, they must wear safety belts.

In flammable and explosive environments, anti-static work clothes and explosion-proof tools should be used.

Equipment safety device inspection

Brake: Check the brake sensitivity and reliability daily, and replace the brake pads if the wear exceeds 50%.

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

Hook: Check whether there are cracks or deformations at the hook mouth, whether the safety buckle is intact, and prevent the load from falling off.

Isolation in hazardous areas

Set up warning lines or signs within the operating range of the equipment to prohibit unrelated personnel from entering.

No one is allowed to stand below the lifting path to avoid injury from falling loads.

3、 Environmental adaptation: Match working conditions to prevent equipment damage

Temperature and humidity control

European style electric hoists are usually suitable for environments ranging from -20 ℃ to+40 ℃, with a relative humidity of ≤ 85%. In high temperature or high humidity environments, it is necessary to strengthen heat dissipation and moisture prevention measures.

In low-temperature environments (such as below -20 ℃), low-temperature grease should be used to prevent gear or bearing jamming.

Explosion proof and anti-corrosion requirements

Explosion proof places: In flammable and explosive environments such as chemical and petroleum industries, explosion-proof electric hoists (such as Ex dIICT4 grade) should be used, and the explosion-proof joint surfaces should be regularly checked for integrity.

Corrosive environment: In corrosive places such as offshore platforms or sewage treatment plants, stainless steel materials or anti-corrosion coating equipment should be selected, and surface salt or chemical substances should be regularly cleaned.

power stability

Confirm that the equipment voltage (such as 380V three-phase AC) matches the on-site power supply, and install a voltage regulator when the voltage fluctuation exceeds ± 10%.

Avoid frequent start stop or long-term overload operation to prevent motor overheating.

4、 Maintenance: Regular inspection and maintenance to extend equipment lifespan

routine inspection

Lubrication and maintenance: Add lubricating grease (such as lithium based grease) to steel wire ropes, drum bearings, reducers, and other parts every week to reduce wear.

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

Electrical system: Check if the wiring is loose and if the insulation resistance meets the standard (≥ 1M Ω).

regular maintenance

Monthly maintenance: Clean the oil stains on the reducer, check the brake clearance (e.g. 0.5-1mm), and adjust it to the specified range.

Annual maintenance: Disassemble and inspect core components such as gears and bearings, replace worn parts, and repaint with anti rust paint.

Fault handling

Immediately stop the machine when a fault is detected and record the symptoms of the fault (such as abnormal noise, oil leakage, limit failure, etc.).

Non professionals are not allowed to disassemble the equipment without authorization and must contact the manufacturer or authorized maintenance organization for handling.

5、 Compliance Management: Comply with regulatory standards to ensure lawful use

Qualifications and Training

Operators must hold a certificate (such as a crane operation certificate) and regularly participate in safety training.

The equipment needs to pass CE certification or ISO quality system certification to ensure compliance with European safety standards.

archival records

Establish equipment archives to record purchase dates, maintenance records, troubleshooting, and other information for easy traceability and management.

Save the operation manual and safety regulations for operators to refer to at any time.

Scrap and update

When the equipment reaches its design lifespan (such as 10 years) or experiences severe wear and tear, it should be promptly scrapped and replaced with new equipment.

When phasing out old equipment, it is necessary to dispose of waste parts in accordance with environmental protection requirements (such as recycling steel wire ropes, motors, etc.).
