1. Introduction
This manual provides essential information for the safe and efficient operation, installation, and maintenance of your BDH Electric Chain Hoist. Please read this manual thoroughly before operating the equipment to ensure proper usage and to prevent injury or damage.
The BDH Electric Chain Hoist is a robust piece of lifting equipment designed for various industrial applications requiring reliable material handling. Manufactured by Henan Best Chain Industry Co., Ltd., these hoists utilize high-precision G80 and G100 grade chains, adhering to national and EU standards for strength and reliability.
2. Consignes de sécurité
AVERTISSEMENT: Le non-respect de ces consignes de sécurité peut entraîner des blessures graves, voire la mort.
- 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.
- Assurez-vous que la charge est correctement arrimée et équilibrée avant de la soulever.
- Ne jamais se tenir directement sous une charge suspendue.
- 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.
- N’utilisez pas le palan pour soulever des personnes.
- In case of malfunction, immediately stop operation and disconnect power.
3. Principaux composants
The BDH Electric Chain Hoist typically consists of the following main components:
- Corps du palan : Contient le moteur, la boîte de vitesses et le système de freinage.
- Chaîne de levage : High-strength G80 or G100 grade chain for lifting loads.
- Crochet de chargement : Swivel hook with safety latch for attaching to the load.
- Sac à chaîne : Collects the slack chain during lifting operations.
- Pendentif de commande : Handheld unit with buttons for controlling hoist movement (Up/Down).
- Chariot (en option) : Allows horizontal movement of the hoist along a beam.
4. Installation et configuration
Proper installation is critical for safe operation. Installation should only be performed by trained and qualified personnel.
- Emplacement de montage : Select a sturdy overhead beam or crane system capable of supporting the hoist's weight plus the maximum rated load.
- 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.
- Connexion électrique : Raccordez le palan à une alimentation électrique appropriée. Vérifiez que le voltage and frequency match the hoist's requirements. Ensure proper grounding to prevent electrical hazards.
- Inspection de la chaîne : Before first use, carefully inspect the entire length of the lifting chain for any damage, twists, or kinks.
- Essai : Perform a test run without a load to verify proper function of the Up/Down controls, limit switches, and braking system.
5. Mode d'emploi
Follow these steps for safe operation of your BDH Electric Chain Hoist:
- Vérification avant utilisation : Before each use, perform a visual inspection of the hoist, chain, hooks, and control pendant. Check for any visible damage, wear, or obstructions.
- Sécurisez le chargement : 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.
- 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.
- Mouvement fluide : Operate the hoist smoothly. Avoid sudden starts or stops, especially with heavy loads.
- Maintain Clearances: Ensure there is sufficient clearance around the load and hoist during operation.
- Interrupteurs de fin de course : 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.
- Après l'opération : 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. Entretien
Un entretien régulier est essentiel pour garantir la longévité et le fonctionnement sûr de votre palan électrique à chaîne.
- Lubrification: Periodically lubricate the lifting chain and other moving parts as recommended by the manufacturer. Use appropriate lubricants.
- Inspection de la chaîne : Regularly inspect the chain for wear, corrosion, stretching, or damage. Replace the chain if any defects are found.
- Inspection du crochet : Check the load hook for deformation, cracks, or excessive wear. Ensure the safety latch operates correctly.
- Système de freinage : Inspect the brake system for proper function and adjustment.
- Composants électriques : Check electrical connections, wiring, and control pendant for damage or loose connections.
- Nettoyage: Keep the hoist clean and free from dirt, dust, and debris.
- Service professionnel : Schedule periodic inspections and maintenance by qualified service technicians.
