Introduction
This manual provides essential instructions for the safe and effective operation, maintenance, and troubleshooting of your Strongway Manual Chain Hoist. This commercial-grade hoist features heat-treated double pawls for reliable brakes and meets ASME B30.16/ASME HST-2:2014 safety standards. It is constructed with a durable high-strength steel frame and gear case, a Grade 80 load chain, and uses lithium grease for optimal performance. The hoist includes tough ductile drop-forged hooks designed to show noticeable opening under excessive overload, enhancing safety. The blackening side plate, zinc-plated hand chain with a rolled-edge design, and asbestos-free friction disc contribute to smooth operation. A cast steel safety latch on the 360° swivel hook further increases safety during use.
Safety Information
WARNING: Failure to follow these safety instructions may result in serious injury or death.
- Always inspect the hoist before each use for any signs of damage, wear, or malfunction. Do not use if damaged.
- Ensure the hoist is securely attached to a suitable support structure capable of safely handling the maximum rated load.
- Never exceed the rated capacity of 4400 lbs (2 tons). Overloading can cause hoist failure.
- Ensure the load is properly balanced and secured before lifting. Use appropriate slings or attachments.
- Keep hands and body clear of the load and moving parts during operation.
- Do not use the hoist to lift people or loads over people.
- Operate the hoist smoothly; avoid sudden jerking or swinging of the load.
- Do not leave a suspended load unattended.
- Ensure the load chain is free of twists, kinks, or damage.
- Wear appropriate personal protective equipment (PPE), including safety gloves and eye protection.
- This hoist meets ASME B30.16/ASME HST-2:2014 safety standards. Adherence to these standards is crucial.
Product Features
- Commercial-grade design: Engineered for performance and durability in demanding environments.
- Heat-treated double pawls: Ensures good spring action and reliable braking mechanisms.
- Safety Standards: Meets ASME B30.16/ASME HST-2:2014 safety standards for industrial hoists.
- Durable Construction: Features a high-strength steel frame and gear case, Grade 80 load chain, and lithium grease for high performance and longevity.
- Overload Protection: Tough ductile drop-forged hooks are designed to show noticeable opening when subjected to excessive overload, providing a visual warning.
- Smooth Operation: Blackening side plate, zinc-plated hand chain with rolled-edge design, and asbestos-free friction disc ensure smooth and consistent operation.
- Enhanced Safety Hook: Cast steel safety latch on the 360° swivel hook increases security during lifting operations.
Setup
- Unpacking: Carefully remove the hoist from its packaging. Inspect for any shipping damage. Report any damage to the supplier immediately.
- Mounting Location: Select a mounting point that is structurally sound and capable of supporting the hoist's weight plus the maximum rated load with an adequate safety factor. This could be a beam, trolley, or other approved overhead support.
- Secure Attachment: Attach the hoist's upper hook securely to the chosen mounting point. Ensure the safety latch on the hook is fully closed and engaged.
- Chain Inspection: Before first use, fully extend the load chain and hand chain. Check for any twists, kinks, damage, or foreign material. Ensure the chain moves freely through the hoist mechanism.
- Test Operation: Perform a test lift with a light load to ensure all mechanisms (lifting, lowering, braking) function correctly.

Operating Instructions
- Connecting the Load: Attach the lower hook securely to the load using appropriate lifting accessories (slings, shackles, etc.). Ensure the safety latch on the lower hook is fully closed and engaged. The 360° swivel hook allows for flexible positioning.
- Lifting the Load: Pull the hand chain downwards to lift the load. Pulling one side of the hand chain will engage the lifting mechanism. Maintain a steady, controlled pull.
- Lowering the Load: To lower the load, pull the other side of the hand chain. The braking mechanism will control the descent. Ensure a slow, controlled lowering motion.
- Braking: The hoist features a reliable braking system that automatically engages when the hand chain is released, holding the load securely in position.
- Load Control: Always maintain control of the load. Avoid swinging or sudden movements.
- After Use: Once the load is safely placed, remove the lower hook. Store the hoist in a clean, dry place, free from corrosive elements.

Maintenance
- Regular Inspection: Conduct daily or pre-shift inspections of the hoist, including the load chain, hand chain, hooks, safety latches, and housing for any signs of wear, damage, or deformation.
- Lubrication: Periodically lubricate the load chain and internal moving parts with lithium grease, as specified for high performance. Refer to the manufacturer's recommendations for lubrication points and frequency.
- Cleaning: Keep the hoist clean and free from dirt, dust, and debris. A clean hoist operates more efficiently and allows for easier inspection.
- Chain Condition: Inspect the load chain for stretching, nicks, gouges, or corrosion. Replace the chain if any damage is found. Ensure the hand chain is also in good condition.
- Hook Inspection: Check hooks for any signs of bending, twisting, or cracks. The ductile drop-forged hooks are designed to show noticeable opening under excessive overload; if this is observed, the hook must be replaced. Ensure safety latches operate freely and fully engage.
- Professional Servicing: For internal component inspection or repair, it is recommended to have the hoist serviced by qualified personnel.
