• Double Pawl System: Enhances safety and reliability during operation by providing redundant braking mechanisms.
• Fixed Chain End Anchorage: Features a special casting for extremely secure anchoring of the load chain, preventing accidental detachment.
• Compact Design: With dimensions of approximately 100 mm (length) x 59 mm (width) x 260 mm (height), it is designed for ease of handling and use in confined spaces.

4. Setup

1. Unpacking and Inspection: Carefully remove the hoist from its packaging. Inspect all components for any signs of shipping damage. Ensure all parts, including the load chain and hooks, are intact and free from deformation or cracks.
2. Mounting the Hoist:
   • Identify a suitable, structurally sound anchor point or trolley system capable of supporting at least five times the maximum intended load.
   • Attach the upper suspension hook of the hoist securely to the anchor point. Ensure the safety latch on the hook is fully closed and engaged.
   • Verify that the hoist hangs freely and vertically, without any obstructions to the chain or housing.
3. Pre-Operational Check: Before lifting any load, perform a test run with a small, non-critical weight to familiarize yourself with the hoist's operation and to confirm all mechanisms are functioning correctly.

5. Operating Instructions

Always operate the hoist with care and attention to safety. Ensure the work area is clear and that no personnel are beneath the suspended load.

1. Attaching the Load:
   • Attach the load securely to the lower swivel load hook. Use appropriate slings, shackles, or other lifting accessories.
   • Ensure the load is centered on the hook and the safety latch is fully closed. Do not tip-load the hook.
   • Verify the load is balanced to prevent swinging during lifting.
2. Lifting the Load:
   • Pull the hand chain downwards steadily and smoothly to lift the load.
   • Avoid sudden or jerky movements.
   • Monitor the load and hoist for any unusual noises or movements.
3. Lowering the Load:
   • To lower the load, gently pull the other side of the hand chain. The speed of lowering is controlled by the rate at which the hand chain is pulled.
   • Lower the load slowly and with control.
   • Once the load is safely on the ground or support, release the hand chain and detach the load hook.
4. Stopping and Holding: The hoist is equipped with a braking system that automatically holds the load when the hand chain is released. Ensure the load is stable before leaving it suspended.

6. Maintenance

Regular maintenance is essential for the safe and reliable operation of your Unicraft chain hoist.

• Daily/Before Use:
  • Visually inspect the entire hoist, including the load chain, hand chain, hooks, and housing, for any signs of damage, wear, corrosion, or deformation.
  • Check that safety latches on both hooks operate freely and close completely.
  • Ensure the load chain runs smoothly through the hoist mechanism.
• Monthly/Regularly:
  • Clean the hoist, especially the chains, to remove dirt, dust, and debris.
  • Lightly lubricate the load chain with a suitable chain lubricant. Avoid over-lubrication, which can attract dirt.
  • Check all fasteners for tightness.
• Annual Inspection: A thorough inspection by a qualified technician is recommended annually to check for internal wear, brake function, and overall structural integrity.
• Storage: Store the hoist in a clean, dry place when not in use to prevent corrosion.
