Analysis of the Characteristics, Application Scale, and Operating Rules of Leveraged Gourd Products

1、 Product Features

Structural and material advantages

Designed using the lever principle, the structure is compact and lightweight (such as aluminum shell models weighing only 3-5kg), making it easy to carry and operate. Typical products such as the German HADEF aluminum ratchet hoist have a lifting capacity ranging from 250kg to 9 tons, suitable for various scenarios such as industrial, explosion-proof, and offshore.

The material is mainly corrosion-resistant all steel structure or high-strength aluminum alloy, and the surface is treated with powder coating (such as orange/black), with strong weather resistance (working temperature range of -40 ℃ to 50 ℃). Some models are equipped with galvanized load chains, which have outstanding corrosion resistance.

Safety and functional design

Equipped with multiple safety devices: automatic load response brake (dual brake claws+4 spring design, exceeding EN 13157 standard), rotating hook (automatically opens instead of breaking when overloaded), RFID chip (for easy maintenance tracking), and hook deformation detection point, ensuring overload recognition and safe operation.

Compliant with CE certification standards, some models support intelligent control (such as TOYO intelligent manual hoist) to improve operational efficiency and accuracy.

Convenience of operation

Ergonomic ratchet lever design, easy to operate (such as small hand pulling force and low wear on steel wire ropes), supports multifunctional operations such as lifting, pulling, lowering, and calibration, and is suitable for non-linear pulling or parallel operation scenarios.

2、 Application scale

Market size and growth

The global manual lever hoist market is expected to reach approximately 1.521 billion US dollars in 2024 and 1.845 billion US dollars in 2031, with a compound annual growth rate of 2.8% (2025-2031). As an emerging market, China's market size will reach billions of yuan by 2024, with demand concentrated in manufacturing, construction, logistics and warehousing industries.

Industry application distribution

Industrial field: equipment installation, loose component bundling, welding alignment (such as electricity, shipbuilding, mechanical manufacturing).

Construction and infrastructure: site hoisting, component handling (such as precast concrete parts, steel structures).

Logistics and warehousing: cargo loading and unloading, stacking (docks, warehouses).

Special scenarios: mining, oil and gas (explosion-proof models), and non electric workplaces (hand-operated hoists).

Regional differences: Europe emphasizes safety and environmental performance; North America prefers efficient and intelligent products; The demand in emerging markets in Asia, such as China and India, is growing rapidly, with a focus on cost-effectiveness and stability.

3、 Operating rules and safety regulations

Pre-operation check

Confirm that the equipment is not damaged: Check that the chain (no breakage/rust), brake, hook (anti loosening device intact), power cord (electric hoist), and limit device are functioning properly.

Clear obstacles in the work area, ensure safe operating space, and ensure that there are no personnel or obstacles in the lifting path.

Precautions during operation

Overloading is strictly prohibited: strictly adhere to the rated load, and prohibit diagonal pulling, lateral lifting, or lifting of objects of unknown weight.

Standardized operation: Apply even force to avoid sudden pulling or too fast operation; Do not press the opposite direction button (electric hoist) at the same time; The direction of the hand zipper should be consistent with the sprocket to prevent it from slipping out of the groove.

Safe distance: During operation, personnel must not be located below or above the load. When heavy objects are suspended, the hand zipper must be fixed to prevent self-locking failure.

Environmental adaptability: Avoid use in environments with corrosive gases, high temperatures, high humidity, or excessive wind; Electric hoists are not suitable for flammable and explosive places (special explosion-proof models are required).

Post operation maintenance

Cut off the power supply (electric hoist), return the equipment to the designated safe location, and add a rain cover for outdoor use.

Regular maintenance: lubricate transmission components (replace lubricating oil every 2 months), check chain wear (once every six months), conduct 25% rated load test annually; Immediately stop using and report for repair upon discovering a malfunction, and do not dismantle or modify safety devices without authorization.

emergency response

In case of malfunction or emergency, immediately stop the machine, cut off the power supply, and report to the responsible person; After the accident, protect the scene, conduct equipment inspection and maintenance, and eliminate hidden dangers before resuming use.
