TKK HSZ-VD Manual Chain Hoist-Heavy Duty Chain Block 0.25 Ton to 100 Ton

The TKK HSZ-VD Manual Chain Hoist is a premium manual lifting solution designed for demanding industrial applications. Built with a rugged steel body and precision-machined transmission components, it provides safe, efficient, and reliable lifting performance for loads ranging from 0.25 ton to 100 tons.
Featuring a patented body design, the hoist delivers increased structural strength while reducing deformation under heavy loads. The compact housing protects internal components from external impact and extends service life in harsh working environments.
For maximum operational safety, the HSZ-VD utilizes a dual pawl braking system that provides double protection during lifting and lowering operations. Even in demanding conditions, the brake maintains stable load holding performance and prevents accidental load slipping.
The hoist is equipped with high-strength G80 alloy steel load chain, offering excellent tensile strength, wear resistance, and fatigue resistance. Precision-calibrated chain links ensure smooth operation with reduced friction and minimal chain twist.
A heat-treated alloy steel gear system provides high transmission efficiency while significantly improving durability during continuous heavy-duty operation. Every gear undergoes precision machining and heat treatment to ensure long service life.
The curled-edge cover design effectively prevents chain jamming and protects internal components from dust and debris. Meanwhile, the dual sealed brake cover helps keep rain, dust, and contaminants away from the braking mechanism, ensuring reliable performance even in challenging outdoor environments.
Each forged hook is manufactured from premium alloy steel through precision forging and heat treatment. Combined with a heavy-duty safety latch, the hooks provide excellent strength, impact resistance, and operational safety.

Every TKK HSZ-VD Manual Chain Hoist is subjected to rigorous quality inspections, including:

• 1.25× Dynamic Load Safety Test
• 1500 Life Cycle Durability Test
• Brake Performance Test
• Load Chain Tensile Strength Inspection
• Gear Transmission Accuracy Test
• Final Functional Inspection Before Shipment

Available in capacities from 250 kg to 100,000 kg, the HSZ-VD series is widely used wherever reliable manual lifting is required. Standard lifting height is 3 meters, while custom lifting heights and special chain lengths are available according to customer requirements.
Whether for equipment installation, machinery maintenance, warehouse handling, or construction lifting, the TKK HSZ-VD Manual Chain Hoist delivers dependable performance, low maintenance requirements, and long service life.
