For the operation of hand cranked hoists (also known as hand cranked hoists or hand cranked cranes), although there is no universal technical operation requirement document directly applicable to all hand cranked hoists, the following technical operation requirements can be summarized based on their working principles, usage scenarios, and safety standards:
1、 Preparation before operation
Equipment inspection: Before operation, a comprehensive inspection of the hand-operated hoist should be conducted, including whether key components such as chains, hooks, handwheels, and braking devices are intact, without cracks, deformations, or excessive wear.
Confirm load: According to the rated load capacity of the hand-operated hoist, confirm whether the heavy object to be lifted is within its bearing range, and overloading is strictly prohibited.
Work environment: Check if the operating environment is safe, ensure there are no personnel or obstacles around, and avoid using in flammable, explosive, or corrosive environments.
2、 Operation process
Correct installation: Install the hand-operated hoist on a stable bracket or lifting point to ensure a secure and reliable installation.
Smooth lifting: During operation, the handwheel should be slowly and steadily shaken to ensure that the heavy object rises or falls smoothly, avoiding sudden acceleration or deceleration.
Attention observation: During the lifting process, the operator should always pay attention to the working status of the hand-operated hoist and the suspension of the heavy object. If there are any abnormalities, the operation should be stopped immediately and checked.
Avoid diagonal pulling: Hand cranked hoists should be used vertically to avoid pulling heavy objects diagonally or sideways, in order to avoid damaging equipment or causing safety accidents.
Reliable braking: After the heavy object reaches the designated position, it should be ensured that the braking device of the hand-operated hoist works reliably to prevent the heavy object from slipping.
3、 Safety precautions
Professional training: Operators should undergo professional training and be familiar with the structure, working principle, and safety operating procedures of hand cranked hoists.
Personal protection: Operators should wear personal protective equipment such as safety helmets, safety shoes, etc.
Prohibition of unauthorized modification: It is strictly prohibited to modify the structure or configuration of the hand cranked hoist without authorization, in order to avoid affecting its performance and safety.
Maintenance: Regularly maintain the hand hoist, check the wear and tear of each component, replace damaged parts in a timely manner, and ensure that the equipment is in good condition.
4、 Operation requirements in special environments
When operating a hand-operated hoist in special environments (such as high temperature, low temperature, humidity, etc.), special attention should be paid to the following:
High temperature environment: Avoid using the hand-operated hoist for a long time in a high temperature environment to prevent damage to its internal components.
Low temperature environment: When using in a low temperature environment, it is necessary to ensure that the lubrication system of the hand-operated hoist is working properly to prevent components from getting stuck due to poor lubrication.
Damp environment: When using in a damp environment, attention should be paid to moisture and moisture prevention to prevent electrical components from being short circuited due to moisture.
