At different stages of operation of manual hoists (manual lifting equipment), the following targeted safety measures should be taken to ensure operational safety, equipment reliability, and personnel protection:

1、 Preparation stage before use

Equipment inspection and confirmation

Structural integrity: Check whether the shell, chain, hook, gear and other components of the manual hoist are intact, without cracks, deformation or severe wear.

Effectiveness of safety devices: Confirm that safety functions such as brakes, limiters, and overload protection devices are functioning properly, such as testing whether the brakes can reliably stop under load.

Lubrication and Cleaning: Check the lubrication condition of the chain to ensure that there are no oil stains or debris stuck; Clean the dust on the surface of the equipment to avoid slipping during operation.

Load matching: Check the rated load and actual load weight of the equipment, and strictly prohibit overloading (such as using a 5-ton hoist to lift a 6-ton object).

Environmental Assessment

Homework space: Ensure that there are no obstacles in the lifting area and no hazards such as high-voltage lines and pipelines above the head; The ground should be flat and solid to prevent the legs from getting stuck or the equipment from overturning.

Weather conditions: When the wind speed exceeds level 5, rainy or snowy weather, or visibility is insufficient, outdoor operations will be suspended.

Lighting and ventilation: Adequate lighting is required for night work; When operating in a confined space, ensure good ventilation to prevent the accumulation of toxic gases.

Personnel and tool preparation

Operation qualification: Operators need to receive professional training, be familiar with equipment performance and operating procedures, and hold certificates to work.

Personal protective equipment (PPE): Wear a safety helmet, non slip shoes, gloves, and use seat belts if necessary (such as for high-altitude operations).

Auxiliary tools: Prepare shims, ropes, warning signs, etc. for fixing loads or delineating warning areas.

2、 Stages during the operation process

Load handling

Binding and fixing: Use specialized lifting devices (such as slings and wire ropes) to bind the load and ensure a stable center of gravity; Sharp edges need to be padded to prevent cutting of lifting equipment.

Lifting angle: Keep the angle between the chain and the vertical direction not exceeding 30 ° to avoid lateral tension causing equipment damage or load slippage.

Trial lifting: Before the formal lifting, slowly lift the load to 10-20cm above the ground, check the force on the brake and chain, and confirm that there are no abnormalities before continuing the operation.

Operating Specifications

Uniform lifting and lowering: Avoid pulling and releasing forcefully to prevent the load from shaking or impacting the equipment; When multiple people work together, they are commanded by a dedicated person and communicate using standard gestures or walkie talkies.

Prohibited behavior:

No one is allowed to stand under the load or within the rotation range of the crane arm;

Do not use gourds to tow vehicles or as welding ground wires;

Equipment shall not be inspected or adjusted during operation.

dynamic monitoring

Load status: Real time observation of whether the load is stable and whether the chain is stuck or jumping teeth; If any abnormalities are found (such as abnormal noise or fever), immediately stop the operation and check.

Environmental changes: Pay attention to changes in environmental factors such as wind direction and ground conditions, and adjust work methods in a timely manner (such as reinforcing wooden pads and adjusting lifting angles).

3、 Closing stage after use

Load placement

Smooth landing: Slowly lower the load to the ground or designated support, ensure stable placement, and then release the lifting device.

Fixed equipment: If the manual hoist needs to be suspended for a long time, raise the hook to the highest position and lock the brake; If disassembly is required, place the equipment in a dry and ventilated dedicated storage area.

Equipment maintenance

Cleaning and maintenance: Remove oil and dust from the surface of the equipment, apply lubricating oil to the chain to prevent rusting.

Troubleshooting: Check the degree of chain wear, brake sensitivity, etc., and record the equipment status; If damaged components (such as broken chain links) are found, replace them immediately and report for repair.

Regular inspection: According to the manufacturer's requirements or industry standards (such as GB/T 30027-2013 "Manual Hoists"), comprehensive testing is conducted regularly to ensure that the equipment performance meets safety standards.

Record and feedback

Homework record: Fill in the operation log, record information such as load weight, homework time, equipment status, etc., to provide a basis for subsequent maintenance.

Hidden danger reporting: If equipment defects or operational risks are found (such as soft site foundations), report to superiors in a timely manner and take corrective measures.
