DY Type Heavy Duty Manual Chain Block For Lifting Purposes

JIN YANG HU DY Heavy-Duty Manual Chain Block is a professional manpower-operated lifting solution specially developed for heavy-load hoisting tasks. This model features a multi-chain parallel structure, which greatly improves load-bearing capacity while maintaining stable force balance during lifting, making it the preferred tool for large-weight cargo handling without power supply.

The housing is constructed with thickened steel plate and finished with durable yellow powder coating, offering excellent impact resistance and corrosion resistance in harsh workshop and construction environments. All load chains are Grade 80 heat-treated alloy steel chains with outstanding tensile strength and wear resistance. The galvanized hand chain ensures smooth pulling operation and rust protection for long-term use.

The upper suspension hook and lower load hook are both drop-forged alloy steel, equipped with safety latches to prevent slings and workpieces from slipping off. The mature friction disc brake system can lock the load securely at any lifting position once pulling stops, effectively avoiding accidental falling and greatly enhancing operation safety. Precision machined internal gear sets reduce pulling resistance for continuous heavy-duty work.

This CE-certified heavy chain hoist covers multiple high-capacity specifications from 10 ton up to 50 ton. The standard lifting height is 3 meters, and customized lifting lengths such as 6m, 9m and longer sizes can be produced according to project requirements.

It is widely used in heavy machinery assembly, equipment maintenance, steel structure engineering, shipyard operation, mining and large factory hoisting occasions. We provide flexible OEM and ODM services, including customized logo printing, special packaging and tailored technical parameters to meet global importers, engineering contractors and wholesale distributors' demands. Every finished hoist undergoes strict load testing before delivery to ensure consistent safety and reliable performance under rated working conditions.
