A triangle chain hoist mainly consists of the following components:
Triangle Housing: Typically forged from high-strength alloy steel, providing robust support and protection.
Transmission System: Includes a drive gear, driven gear, and load sprocket, forming a two-stage spur gear reduction mechanism.
Hand Chain (Operating Chain): Pulled by the operator to drive the internal gears.
Lifting Chain (Load Chain): Directly connected to the hook for lifting heavy objects.
Upper/Lower Hooks: Usually equipped with a tongue to prevent chain slippage, used to connect the load and the anchor point.
Brake: The core safety device, typically employing a friction ratchet brake system, automatically braking at any position to prevent the load from falling.
Ratchet and Pad: Form a one-way mechanism, ensuring that the load can only be lifted or held, and cannot be reversed.
