The core advantages of a lever hoist (often mistakenly referred to as a "lever Gourd") are reflected in five dimensions: mechanical efficiency, operational flexibility, safety and reliability, environmental adaptability, and economic value, as follows:

1. Mechanical efficiency and operational advantages

High mechanical advantage: Amplify manpower through the principle of leverage, with typical mechanical advantages ranging from 15:1 to 30:1. For example, a force of 30 kilograms can lift a load of 500 kilograms, achieving millimeter level precision control, suitable for scenarios that require fine adjustments such as equipment installation and art hoisting.

Multi directional operation capability: supports vertical, horizontal, and inclined multi angle operations, different from the traditional chain hoist's single vertical lifting. For example, heavy steel can be dragged horizontally on construction sites, and deformed vehicles can be tilted and lifted during rescue operations.

Portability and compact design: The lightweight aluminum alloy or carbon fiber body (such as the Yale series, which reduces weight by 30%) combined with a 360 ° rotating handle makes it easy to work in narrow spaces (such as attic or mine) or at heights, similar to a "telescopic robotic arm".

2. Safety and reliability

Double overload protection: mechanical pawl locking and electronic sensor dual protection, automatically locking and triggering an alarm when overloaded, in compliance with OSHA, CE, and ISO 4304-1 standards. For example, the dual pawl design automatically locks into the ratchet teeth slot when overloaded, preventing chain breakage.

Fall prevention and braking system: spring braking+hydraulic buffering dual braking design, braking response time ≤ 0.5 seconds; Self locking safety hooks prevent load shedding, and some models integrate LED status indicator lights to enhance operational visibility.

Structural durability: Wear resistant chains with a chain ring diameter wear of ≤ 10% paired with low friction guide rails have a design lifespan of over 10 years; ISO 12944 C5M anti-corrosion coating or stainless steel components (such as SS19 Subsea model) can resist 54 days of salt spray corrosion and adapt to harsh environments such as offshore and chemical.

3. Environmental adaptability and special applications

Extreme environment adaptation: The dust-proof sealing structure is suitable for mining dust environments, and the high/low temperature resistant design is suitable for metallurgy and polar operations; Explosion proof models meet the requirements of flammable and explosive scenarios such as chemical plants and oil and gas fields.

Creative and rescue applications: can lift the engine in car maintenance, pick tall fruits in orchards, and achieve precise positioning in art installation; In rescue scenarios, vehicles can be dragged and collapsed building components can be lifted to assist personnel in escaping.

4. Maintain convenience and economic value

Modular and easy to maintain design: Annual professional maintenance includes disassembly and inspection of internal components (such as gearboxes and bearings), replacement of worn parts (such as chain links and brake pads); Self lubricating bearings reduce lubrication requirements and extend maintenance cycles to 1-2 years.

Cost effectiveness: Compared to electric/hydraulic lifting equipment, manual lever lifts have lower initial procurement costs, lower maintenance expenses, and do not require power supply, making them suitable for operations in unstable or remote areas.

Intelligent integration trend: Integrating Bluetooth/Wi Fi modules for remote monitoring, AI driven diagnosis and prediction of component wear, supporting data exchange with warehouse management systems, improving equipment utilization and predictive maintenance capabilities.

5. Industry standards and certifications

Adhere to international standards (such as ISO 4304-1, OSHA 1926.1401) and domestic standards (such as GB/T 14736-2009, GB 6067.1-2010) to ensure equipment safety technical requirements and operating specifications.

By obtaining certifications such as CE and UL, we meet global market access requirements and support cross-border project collaboration.
