2. Hướng dẫn an toàn

CẢNH BÁO: Không tuân theo các hướng dẫn an toàn này có thể dẫn đến thương tích nghiêm trọng hoặc tử vong.

  • Always inspect the hoist, chain, and hooks before each use for any signs of wear, damage, or deformation.
  • Do not exceed the rated load capacity of the hoist. Refer to the hoist's label for specific capacity.
  • Ensure the load is properly secured and balanced before lifting.
  • Never stand directly under a suspended load.
  • Keep hands and body clear of moving parts, especially the chain and hook.
  • Do not use the hoist if the chain is twisted, kinked, or damaged.
  • Ensure the power supply matches the hoist's requirements and is properly grounded.
  • Only qualified personnel should operate, install, or maintain the hoist.
  • Do not use the hoist for lifting people.
  • In case of malfunction, immediately stop operation and disconnect power.

3. Các thành phần chính

The BDH Electric Chain Hoist typically consists of the following main components:

  • Hoist Body: Contains the motor, gearbox, and braking system.
  • Lifting Chain: High-strength G80 or G100 grade chain for lifting loads.
  • Móc tải: Swivel hook with safety latch for attaching to the load.
  • Túi dây xích: Collects the slack chain during lifting operations.
  • Control Pendant: Handheld unit with buttons for controlling hoist movement (Up/Down).
  • Trolley (Optional): Allows horizontal movement of the hoist along a beam.

4. Cài đặt và thiết lập

Proper installation is critical for safe operation. Installation should only be performed by trained and qualified personnel.

  1. Vị trí lắp đặt: Select a sturdy overhead beam or crane system capable of supporting the hoist's weight plus the maximum rated load.
  2. Hoist Mounting: Securely attach the hoist to the beam using an appropriate trolley system (if applicable) or fixed suspension. Ensure all bolts and fasteners are tightened to the manufacturer's specifications.
  3. Kết nối điện: Connect the hoist to a suitable power supply. Verify that the voltage and frequency match the hoist's requirements. Ensure proper grounding to prevent electrical hazards.
  4. Kiểm tra chuỗi: Before first use, carefully inspect the entire length of the lifting chain for any damage, twists, or kinks.
  5. Chạy thử: Perform a test run without a load to verify proper function of the Up/Down controls, limit switches, and braking system.

5. Hướng dẫn vận hành

Follow these steps for safe operation of your BDH Electric Chain Hoist:

  1. Kiểm tra trước khi vận hành: Before each use, perform a visual inspection of the hoist, chain, hooks, and control pendant. Check for any visible damage, wear, or obstructions.
  2. Cố định hàng hóa: Attach the load hook securely to the item to be lifted. Ensure the safety latch on the hook is closed. The load must be balanced to prevent swinging.
  3. Control Pendant Usage: Use the 'Up' button on the control pendant to lift the load and the 'Down' button to lower it. For hoists with a trolley, use the directional buttons (Left/Right or Forward/Backward) to move the hoist horizontally.
  4. Chuyển động mượt mà: Operate the hoist smoothly. Avoid sudden starts or stops, especially with heavy loads.
  5. Duy trì giấy phép an ninh: Ensure there is sufficient clearance around the load and hoist during operation.
  6. Công tắc giới hạn: Do not rely solely on limit switches to stop the hoist. Always release the control button before the load reaches its upper or lower limit.
  7. Sau khi hoạt động: Once the lifting task is complete, lower the hook to a safe resting position and disconnect power if the hoist will not be used for an extended period.

6. Bảo trì

Regular maintenance is essential to ensure the longevity and safe operation of your electric chain hoist.

  • Bôi trơn: Periodically lubricate the lifting chain and other moving parts as recommended by the manufacturer. Use appropriate lubricants.
  • Kiểm tra chuỗi: Regularly inspect the chain for wear, corrosion, stretching, or damage. Replace the chain if any defects are found.
  • Kiểm tra móc: Check the load hook for deformation, cracks, or excessive wear. Ensure the safety latch operates correctly.
  • Hệ thống phanh: Inspect the brake system for proper function and adjustment.
  • Linh kiện điện: Check electrical connections, wiring, and control pendant for damage or loose connections.
  • Vệ sinh: Keep the hoist clean and free from dirt, dust, and debris.
  • Dịch vụ chuyên nghiệp: Schedule periodic inspections and maintenance by qualified service technicians.
