Safety Information

Always prioritize safety when operating lifting equipment. Failure to follow these safety guidelines can result in serious injury or property damage.

• Capacity Limits: Never exceed the rated capacity of 2200 lbs (1000 kg). Overloading can cause hoist failure.
• Inspection: Before each use, inspect the hoist, load chain, and hooks for any signs of wear, damage, or deformation. Do not use if any defects are found.
• Load Security: Ensure the load is properly secured and balanced before lifting. The load hook must be fully engaged with the load.
• Hook Safety Latches: Always ensure hook safety latches are functional and properly closed. Ductile drop-forged hooks are designed to show noticeable opening if subjected to excessive overload, indicating a need for replacement.
• Operating Environment: Use the hoist in a clear area, free from obstructions. Keep hands and body clear of the load and moving parts.
• Standards Compliance: This hoist meets ASME B30.21/HST-3 safety standards and has a safety coefficient of at least 4:1.
• Chain Management: Ensure the load chain is free of twists, kinks, or knots before and during operation.
• Personnel: Only trained and authorized personnel should operate the hoist.

Product Components

Familiarize yourself with the main components of your lever chain hoist:

1. Upper Hook: Used for attaching the hoist to a secure anchor point.
2. Lever Handle: Used to operate the lifting and lowering mechanism.
3. Control Lever/Selector: Switches between UP, NEUTRAL, and DOWN modes.
4. Hoist Body/Gear Case: Houses the internal lifting mechanism and brake system.
5. Load Chain: Grade 80 chain that supports and moves the load.
6. Lower Hook: Used for attaching to the load.

Setup

Proper setup is crucial for safe and efficient operation.

1. Secure Anchor Point: Attach the upper hook of the hoist to a structural member or trolley that is rated to safely support the hoist's weight plus the maximum intended load. Ensure the anchor point is stable and secure.
2. Hoist Orientation: Ensure the hoist hangs vertically and the load chain is free to move without obstruction.
3. Chain Inspection: Pull the load chain through the hoist to ensure it moves freely and is not twisted or kinked.
4. Test Operation: Before attaching a load, perform a few cycles of lifting and lowering with no load to confirm smooth operation of the lever and chain.

Operating Instructions

Follow these steps for safe lifting and lowering operations.

Lifting a Load

1. Attach Load: Securely attach the lower hook to the load. Ensure the safety latch is closed.
2. Select UP Mode: Move the control lever to the "UP" position.
3. Operate Lever: Pump the lever handle up and down to lift the load. Each stroke will raise the load incrementally. Maintain a steady, controlled motion.
4. Monitor Load: Continuously observe the load and hoist for any signs of instability or strain.

Lowering a Load

1. Select DOWN Mode: Move the control lever to the "DOWN" position.
2. Operate Lever: Pump the lever handle up and down to lower the load. The speed of lowering is controlled by the rate of pumping.
3. Controlled Descent: Lower the load slowly and steadily to its desired position.

Free Chaining (No Load)

To quickly adjust the chain length without a load:

1. Select NEUTRAL Mode: Move the control lever to the "NEUTRAL" position.
2. Adjust Chain: Manually pull the load chain to the desired length. This mode disengages the brake, so ensure there is absolutely no load on the hook.
3. Re-engage: Return the control lever to "UP" or "DOWN" before applying any load.

Maintenance

Regular maintenance ensures the longevity and safe operation of your hoist.

• Lubrication: Periodically lubricate the load chain and internal mechanisms with lithium grease or a similar high-quality lubricant. Refer to the manufacturer's recommendations for specific lubrication points and frequency.
• Chain Inspection: Regularly inspect the entire length of the load chain for wear, corrosion, nicks, gouges, or stretched links. Replace the chain if any damage is found.
• Hook Inspection: Check both upper and lower hooks for deformation, cracks, or excessive wear, especially at the throat opening. Ensure safety latches operate freely and fully close.
• Brake System: The heat-treated double pawl, 3-piece disc brake system is designed for reliability. If the brake feels less responsive, have it inspected by a qualified technician.
• Cleaning: Keep the hoist clean and free from dirt, debris, and corrosive materials.
• Storage: Store the hoist in a dry, clean environment when not in use.
