Hand pulled hoist is a compact and easy to operate manual lifting tool, widely used in various places such as factories, warehouses, construction sites, etc., especially suitable for working environments without power supply and small space, becoming a powerful assistant for short distance lifting of heavy objects. It can lift heavy objects manually without relying on electricity or other power equipment, combining portability and practicality.
The core safety guarantee of the chain hoist is the built-in ratchet and pawl brake, which is also a key feature that distinguishes it from ordinary lifting tools. The braking system is composed of precision matched components such as ratchet, pawl, friction plate, etc. It adopts a one-way braking design and can automatically lock under load, fundamentally eliminating the hidden danger of heavy objects falling. When pulling the hand zipper to lift heavy objects, the claws are engaged with the ratchet under the action of the spring to prevent reversal; When stopping pulling or accidentally releasing, the load's gravity triggers the brake, and the pawl quickly engages with the ratchet teeth, firmly locking the transmission mechanism and allowing the heavy object to hover steadily in the air without additional operation to achieve safe locking.
In addition to reliable braking performance, the chain hoist also relies on the principle of labor-saving lever and gear transmission to amplify the small force applied manually, easily lifting heavy objects several times that of human labor, balancing labor-saving and efficiency. Its structure is simple, mainly composed of a hook, a lifting chain, a transmission mechanism, and an outer shell. The outer shell is made of high-quality steel, which can effectively protect internal components and adapt to complex working environments.
Hand pulled hoists play an irreplaceable role in equipment maintenance, cargo loading and unloading, construction, and other scenarios due to their advantages of safety, reliability, easy operation, and portability. They have become safety helpers in industrial production and daily operations.
