Product Description: Tianjin Kemei Machinery Manufacturing Co., Ltd. is a modern production - oriented enterprise integrating independent R & D, manufacturing, and sales. It is located in the beautiful coastal city of Tianjin, enjoying a unique geographical location, convenient transportation, and smooth logistics. The company is committed to the development and manufacture of stage entertainment hoisting products. Its main products include stage - specific endless chain electric hoists, stage - specific hand - operated hoists, black lifting slings, group control boxes, rail clamps, and auxiliary products. These products are widely used in the fields of truss construction for concerts, conference halls, exhibition set - ups, high - end customized weddings, and various celebration performances. Product Specifications: 1. It adopts international G80 - grade lifting chains, featuring good safety performance and corrosion resistance. 2. The protection level reaches IP44 with a waterproof design, and it has passed the tests of rain and water immersion. 3. It is equipped with a mechanical overload protection device and an anti - oil - leakage setting. 4. The outer shell of the whole machine is made of aviation aluminum, making the body lighter. Safety Operating Procedures for Stage Electric Hoist I. Pre - operation Preparations Operator Qualifications Operators must undergo professional training, be familiar with the structure, performance, and operation methods of stage electric hoists, and hold relevant operation certificates. Uncertified personnel are strictly prohibited from operating. Equipment Inspection 1. Appearance Inspection: Check whether the overall electric hoist is damaged or deformed, whether the shell is cracked, whether the chain is twisted, worn, or has cracks, and whether the chain pins are loose.

2. Brake System Inspection: Manually test the braking device to ensure reliable braking. Both the electromagnetic brake and the mechanical emergency brake must work properly.

3. Limit Switch Inspection: Trigger the upper and lower limit switches to check whether the electric hoist can stop running in a timely manner. At the same time, confirm whether the position of the limit blocks is appropriate and can meet the actual working requirements.

4. Power System Inspection: Check the appearance of the motor to ensure that the wiring is firm and there is no risk of electric leakage. Use a clamp - on ammeter to measure whether the no - load current fluctuation is within the specified range.

5. Protection Device Inspection: Confirm whether the protection level meets the requirements and whether the waterproof, dust - proof, and other protective measures are in good condition. Working Environment Inspection 1. Clean the working area to ensure that there are no obstacles around, there is sufficient space above, and there are no objects affecting the operation of the electric hoist.

2. Check the bearing capacity of the lifting point to ensure that it can bear the total weight of the lifted object and the electric hoist. Reinforce or replace it if necessary.

3. Confirm that the on - site power supply meets the voltage and frequency requirements of the electric hoist and is equipped with an effective leakage protection device. II. Operation Process Specifications Lifting Operation 1. Correctly connect the lifting tool to the lifted object to ensure a firm connection. The center of gravity of the lifted object should be perpendicular to the hook to avoid eccentric lifting.

2. Slowly press the upward button to make the lifted object rise smoothly. Closely observe the state of the object during the rising process. Stop immediately if there is any abnormality. Running Operation 1. During the hoisting process, keep the operation at a constant speed, avoid sudden acceleration or deceleration, and prevent the lifted object from swaying too much.

2. Control the running direction of the electric hoist. Collision with surrounding objects is strictly prohibited. Pay close attention to the surrounding environment and personnel safety at all times.

3. When multiple electric hoists are controlled in groups, ensure that the synchronization error is within the specified range to avoid the object tilting or falling off due to asynchronous operation. Lowering Operation 1. When the lifted object reaches the designated position, slowly press the downward button to make the object descend smoothly.

2. During the descending process, closely observe the distance between the object and the ground or the placement point. Reduce the descending speed when approaching. III. Post - operation Precautions

Stop Operation

After the object is hoisted and transported, immediately press the stop button and turn off the power supply of the electric hoist. Equipment Arrangement

Remove the lifting tool from the hook and the lifted object, arrange them neatly, and store them in the designated location. Clean the surface of the electric hoist and the debris in the working area. Record and Report Record relevant information about this use, including the use time, the lifted items, the operation status of the equipment, etc. If any abnormalities or malfunctions are found during the operation, report them to the relevant maintenance personnel in a timely manner and describe the fault phenomena in detail. IV. Emergency Handling

Sudden Malfunctions

If malfunctions such as abnormal noise, vibration, or brake failure occur during the operation of the electric hoist, immediately press the emergency stop button and take corresponding measures to prevent the accident from expanding, such as setting warning signs and evacuating surrounding personnel. Emergency Power Off

When an emergency requires power off, quickly cut off the main power switch and set a warning sign at the power switch to prevent others from accidentally closing the switch.
