3. Persediaan
Persediaan yang betul adalah penting untuk operasi yang selamat dan berkesan.
- Membongkar dan Pemeriksaan Awal:
Carefully remove the hoist from its packaging. Inspect all components for any signs of shipping damage. Ensure all chains move freely and the hooks operate correctly. The hoist may arrive with a protective oil coating; it is recommended to wear gloves during initial handling.
- Mounting the Hoist:
Identify a suitable overhead support structure (e.g., I-beam, gantry crane, or sturdy frame) that can safely support the hoist's weight plus the maximum intended load. The support structure must be rated for the combined weight. Attach the upper hook of the hoist securely to this support. Ensure the safety latch on the hook is fully closed and engaged.

- Menyediakan Beban:
Ensure the load to be lifted is stable and has appropriate attachment points. Use suitable slings, chains, or other lifting accessories that are rated for the load's weight. Attach these accessories to the lower hook of the hoist. Verify the safety latch on the lower hook is also fully closed and engaged.

4. Arahan Operasi
Ikuti langkah ini untuk operasi yang selamat dan cekap:
- Mengangkat Beban:
To lift the load, pull the hand chain downwards. The mechanical load brake will engage automatically to hold the load in position when you stop pulling. Pull the chain smoothly and steadily. Avoid jerky movements.
- Menurunkan Beban:
To lower the load, pull the other side of the hand chain. The load will descend gradually. Control the descent speed by the rate at which you pull the chain. Never release the hand chain abruptly.
- Positioning the Load:
Use the hand chain to precisely position the load. The load-sharing gears make lifting and lowering heavy loads manageable with minimal effort.
- Selepas Operasi:
Once the load is safely positioned or lowered, remove the lifting accessories from the lower hook. Store the hoist in a clean, dry place, free from corrosive elements.

5. Penyelenggaraan
Regular maintenance ensures the longevity and safe operation of your hoist.
- Pemeriksaan Harian: Before each use, visually inspect the hoist for any signs of damage, wear, or corrosion on the chains, hooks, and housing. Check that safety latches on the hooks operate freely.
- Pelinciran: Periodically lubricate the load chain and internal moving parts according to manufacturer recommendations. Use a high-quality lubricant suitable for chain hoists.
- Pembersihan: Keep the hoist clean and free from dirt, grime, and debris. A cold rolled steel cover protects the chains and gear system, but external cleaning is still important.
- Chain Condition: Inspect the load chain for stretched links, nicks, gouges, or corrosion. Replace the chain if any damage is found.
- Hook Condition: Check hooks for bending, twisting, or cracks. Ensure the safety latches are functional and not bent or damaged.
- Perkhidmatan Profesional: For complex repairs or internal component issues, consult a qualified service technician.
