A lever chain hoist is a lightweight lifting tool designed based on the principle of leverage. Its core function is to achieve vertical lifting, horizontal traction, precise descent, and position calibration of heavy objects through manual or electric drive. It is widely used in industry, construction, logistics, and special environmental operations. Its functional characteristics can be systematically summarized into the following dimensions:

1、 Basic lifting function

Vertical lifting and lowering: Precise lifting and lowering of heavy objects is achieved through ratchet levers or motor-driven chains/wire ropes. For example, the German HADEF aluminum hoist can cover a lifting capacity of 250kg to 9 tons, meeting the needs of equipment installation, loose parts bundling, and other scenarios.

Horizontal traction and calibration: equipped with 360 ° rotating hooks or swivel rings (such as Haklift VTS series), supporting non-linear traction and narrow space operations, suitable for precise positioning scenarios such as welding alignment and component adjustment.

2、 Security protection function

Multiple safety devices:

Automatic load response brake: adopting a dual brake claw+4 spring design, triggering the brake when overloaded, in compliance with EN 13157 standard, to prevent the risk of falling objects.

Rotating hook and anti loosening device: When overloaded, the hook automatically opens instead of breaking, avoiding secondary injury caused by breakage; The hook deformation detection point monitors the wear status in real-time.

Limit and emergency stop system: The electric hoist is equipped with upper and lower limit switches and emergency stop buttons to prevent tipping or overtravel operations.

RFID tracking and intelligent monitoring: Some models integrate RFID chips to achieve maintenance record tracking; Intelligent gourds (such as TOYO series) support IoT data transmission, real-time monitoring of load, location, and device status.

3、 Environmental adaptation and special functions

Weather resistance and anti-corrosion design: using high-strength aluminum alloy or corrosion-resistant steel structure, surface treated with powder coating (such as orange/black), working temperature range of -40 ℃ to 50 ℃, suitable for high temperature, high humidity, corrosive gas environment; The explosion-proof model complies with the ExIIBT4 standard and is suitable for flammable and explosive scenarios such as oil and gas, mining, etc.

Lightweight and portable: The aluminum shell model weighs only 3-5kg and has a compact structure, making it easy to carry to high altitudes, narrow spaces, or workplaces without electricity (such as hand cranked hoists).

Intelligent upgrade: integrating frequency conversion control and remote monitoring functions, realizing operation speed adjustment, fault warning, and remote diagnosis, improving work efficiency and accuracy.

4、 Operation process and scene adaptation

Standardized operating procedures: Following the full process specification of "pre operation inspection - monitoring during operation - post operation maintenance", including chain/brake status inspection, no-load testing, uniform force application, safety distance maintenance, and regular lubrication maintenance (changing lubricating oil every 2 months and checking chain wear every 6 months).

Scenario based application:

Industrial field: equipment installation, welding alignment, and loose component bundling (power, shipbuilding, mechanical manufacturing).

Construction and infrastructure: lifting of precast concrete components, handling of steel structural components, and safety protection for high-altitude operations.

Logistics and warehousing: dock loading and unloading, warehouse stacking, and shelf layout adaptation.

Special environment: Explosion proof area, high temperature area, and places without electricity (hand cranked hoist+backup power source).

5、 Future Development Trends

With the increasing demand for intelligence and environmental protection, lever hoists are evolving towards high performance, intelligence, and environmental protection:

High performance: using recycled materials, enhancing structural strength, and improving the matching efficiency between lifting capacity and rotation radius.

Intelligence: Integrating AI algorithms to achieve automatic load recognition, path planning, and fault prediction, supporting remote control and data visualization.

Environmental Protection: Utilizing energy recovery systems and low-energy motors to reduce carbon emissions, in line with the trend of green manufacturing.
