Product Details

HSVS Series Chain Block Features:

High-strength chain, excellent load-bearing. The lifting chain is forged with high-quality alloy steel. After special heat treatment, the hardness reaches HRC40-45 and the tensile strength is ≥1000MPa, which is 30% higher than the load-bearing capacity of ordinary chains. The surface of the chain is rust-proofed, the thickness of the galvanized layer is ≥8μm, and it is resistant to salt spray corrosion for more than 500 hours, which is suitable for harsh working environments such as humidity and dust. For example, when lifting goods in a chemical warehouse, the chain is not easy to rust, and the service life is extended by 2-3 years, ensuring long-term stable operation.
Precision gear transmission, labor-saving and efficient. The gear set is made of high-carbon steel, and the tooth surface is carburized and quenched. The precision reaches 7 levels and the transmission efficiency is as high as 80%. It adopts a 3-5-level reduction design, which is reasonably configured according to the different lifting weights, so that the pulling force is more balanced and the operation is more labor-saving. For example, the 2-ton CK chain hoist only requires 150-200N of force to pull the chain, which is 20%-30% lower than similar products, effectively reducing the labor intensity of operators and improving work efficiency.
Anti-slip hand chain, safe operation. The surface of the hand chain is knurled to increase friction and prevent hands from slipping, ensuring a stable grip even when working in wet conditions or with gloves. The chain fits tightly with the sprocket, runs smoothly, and there is no tooth skipping or chain jamming, ensuring safe and reliable operation. At the construction site, workers can easily operate with one hand to avoid accidents caused by chain slippage.
Sturdy shell protection, durable and resistant. The shell is made of high-strength aluminum alloy or cast steel. The aluminum alloy model is light and easy to carry, suitable for high-altitude or frequently moving operations; the cast steel model has high strength and good impact resistance, suitable for harsh working conditions. The shell is precisely cast and machined, with a smooth and flawless surface and good sealing. It is effectively dustproof, waterproof and oil-proof, with a protection level of IP54. The internal parts are reliably protected, extending the overall service life of the equipment.

HSVS Series Chain Block Typical Applications:

Industrial manufacturing scenarios. In mechanical processing plants, it is used to lift small machine tool parts, molds, etc., and the lifting weight is usually 1-5 tons. CK hand chain hoists can be accurately positioned, making it convenient for workers to install and debug equipment, reducing assembly problems caused by lifting errors, and improving production efficiency by 20%-30%. In electronic product manufacturing workshops, precision instruments and electronic components are lifted, and its stable lifting characteristics avoid damage to products caused by vibration, ensuring product quality.
Construction field. Construction sites lift building materials such as bricks and small prefabricated parts (0.5-3 tons). Workers can easily operate on scaffolding and flexibly adjust the lifting position to meet different construction needs. In interior decoration, it is used to lift lamps, ceilings, etc. The lifting height can be precisely controlled to ensure installation accuracy and improve decoration quality.
Warehousing and logistics industry. For warehouse cargo stacking and loading and unloading, CK hand chain hoists can be used with shelves and gantry frames to lift goods to designated locations and improve storage space utilization. At the logistics transfer station, the handling of small containers and pallet goods (2 - 8 tons) is easy to operate and is not limited by the site power supply. It can quickly complete the transfer of goods and ensure smooth logistics trat he operation is more labor-saving. For example, the 2-ton CK chain hoist only requires 150-200N of force to nsportation.

FAQ

Q1: How to store the chain hoist when it is not used for a long time?

A: The chain hoist should be cleaned, and anti-rust oil should be applied to the chain, gears and other parts. It should be stored in a dry, ventilated environment without corrosive gases. Avoid direct sunlight and heavy objects. It can be hung or placed horizontally on the shelf. Check regularly (every 3-6 months) to ensure normal performance when it is used next time.
Q3: What should I do if the chain is stuck during use?

A: Stop the operation immediately. It is strictly forbidden to pull it forcefully. Check whether there is any foreign matter entangled or twisted in the chain, and whether the sprocket and chain are meshing normally. If there is any foreign matter, clean it carefully; if the chain is twisted, try to pull it in the reverse direction slowly to adjust it. If the problem still cannot be solved, it is necessary to disassemble and check the internal structure. If necessary, replace the damaged parts. It is strictly forbidden to continue to use it when the chain is stuck to avoid damaging the equipment or causing safety accidents.
Q3: What is the reason for the brake failure of the chain hoist?

A: Possible causes of brake failure include: severe wear of the brake pads, too large a gap, and ineffective braking; oil and debris in the brake device, which affects the braking effect; spring failure, which cannot provide sufficient braking force. The solution is to replace the worn brake pads, clean the brake device, and check and replace the failed springs. During daily maintenance, check the brake system regularly to ensure its reliability.
