When using European style wire rope electric hoists, strict control must be exercised from five dimensions: operating standards, equipment inspection, environmental management, safety protection, and emergency response to ensure operational safety and equipment lifespan. The following are specific precautions:

1、 Operating standards: Strictly follow the process and eliminate illegal operations

Certified employment and training

Operators need to undergo professional training, familiarize themselves with equipment performance, safety regulations, and emergency measures, and hold operating qualification certificates.

Regular refresher training to update awareness of new models or upgraded features.

load management

Overloading is strictly prohibited: the lifting capacity shall not exceed 90% of the rated load (some models allow short-term overloading of 10%, but the time must be strictly limited).

Uniform distribution: The center of gravity of the lifted object should be perpendicular to the center of the hook to avoid overturning caused by unbalanced load.

Secure binding: Use specialized lifting equipment to ensure that there is no risk of loosening or sliding of the lifted object.

speed control

Lifting/lowering: operate at a constant speed to avoid sudden stops and starts; When lifting precision equipment, the speed should be ≤ 0.5m/min.

Operating mechanism: The horizontal movement speed should match the lifting speed to prevent the lifting object from shaking.

multi-person collaboration

Designate a dedicated person to command, and the operator and commander maintain real-time communication through wireless intercom or gestures.

Avoid multiple people operating the same device at the same time to prevent signal conflicts.

2、 Equipment inspection: daily inspection+regular maintenance to eliminate hidden dangers

Daily inspection items

Wire rope: Check for broken wires, wear, and rust. If the number of broken wires exceeds 10% of the total number of wires, they should be replaced immediately.

Brake: Test the thickness of the brake pads (replace if remaining ≤ 3mm) to confirm that the brake response is sensitive.

Limit device: manually trigger the upper and lower limit positions to verify whether it can automatically shut down.

Electrical system: Check if the wiring terminals are loose and if the insulation resistance is greater than 1M Ω.

Weekly maintenance content

Clean the surface oil stains of the equipment to prevent dust accumulation from affecting heat dissipation.

Check the straightness of the track and adjust if the deviation exceeds ± 5mm.

Lubricate the gears and bearings of the lifting mechanism using high-temperature resistant lithium grease.

Monthly in-depth maintenance

Disassemble and inspect the brake friction plate and spring tension.

Test the insulation performance of the motor and perform drying treatment if necessary.

Verify the overload protection device to ensure that an alarm is triggered when an overload of 10% occurs.

3、 Environmental management: Adapt to work scenarios and avoid environmental risks

Temperature and humidity control

High temperature environment (>40 ℃): Strengthen motor heat dissipation and avoid prolonged continuous operation.

Low temperature environment (<-20 ℃): Use low-temperature grease and preheat the equipment before starting.

Damp environment: Place desiccants inside the electrical cabinet and regularly check for condensation water.

Protection against corrosive media

Chemical/Coastal Scenarios: 316 stainless steel wire rope and IP66 protection level electrical cabinet are selected.

Clean the equipment promptly after homework and apply rust proof oil.

Explosive risk mitigation

In flammable and explosive places (such as paint workshops), explosion-proof models (Exd Ⅱ CT4 certification) must be used.

It is prohibited to use non explosion proof tools or mobile phones in the explosion-proof area.

Space restriction handling

Low clearance scenario: Choose a short shaft electric hoist with a coupling to reduce installation height.

Narrow passage: Install anti-collision devices to avoid collisions with walls or equipment.

4、 Security protection: Building multi-level protective barriers

Personal Protective Equipment (PPE)

Operators are required to wear safety helmets, anti slip shoes, and insulated gloves.

Wear a safety belt and secure the safety rope to an independent anchor point during high-altitude operations.

Equipment safety device

Double limit: Both the upper and lower limits need to work independently to avoid single fault failure.

Cable protection: Built in angle sensor, automatically stops when cable angle>3 °.

Emergency stop button: red mushroom shaped, response time<0.3 seconds.

Isolation of homework area

Set up a warning zone below the lifting path and hang a "No Entry" sign.

Use laser or infrared sensing devices to trigger alarms when personnel enter.

5、 Emergency response: rapid response, reducing accident losses

Emergency response to malfunctions

Brake failure: Immediately press the emergency stop button to switch to the backup brake.

Wire rope breakage: Quickly evacuate the alert area and activate the backup hoist to transfer the lifted object.

Electrical fire: Use dry powder fire extinguishers and do not use water to extinguish fires.

Accident reporting process

Report to the safety management department within 1 hour after the accident occurs, and retain on-site photos and video evidence.

Cooperate with the investigation, analyze the reasons (such as overloading, operational errors, equipment aging), and develop corrective measures.

emergency drill

Organize a quarterly drill to simulate scenarios such as brake failure and falling objects.

Evaluate response time, collaboration efficiency, and optimize emergency plans after the drill.

6、 Additional precautions for special scenarios

Explosion proof environment operation

Before starting work, check if the explosion-proof mark (Exd Ⅱ CT4) is clear and if the junction box seal is intact.

It is prohibited to dismantle or repair equipment within the explosion-proof area.

Clean room use

Choose oil-free lubrication models to avoid lubricating oil volatilization and environmental pollution.

Wipe the equipment with a dust-free cloth after homework to prevent particle residue.

Application in the food/pharmaceutical industry

Electrical cabinets and wire ropes must be FDA certified and made of materials that meet food grade standards.

Regularly conduct microbiological testing to ensure no contamination risk.
