VT Chain Blocks are a portable lifting device easily operated by hand, which can be attached to a trolley of any type as a traveling chain blocks and one kind of using simply and carrying easily manual hoisting machinery. After absorbing the advanced technology in the world, VT series chain hoist is improved on the basis of HSZ series. Except for the traditional characteristics of HSZ series chain hoist, VT type chain hoists need less hand-pull force, and they are safer, more beautiful and applicable. VT chain hoists adopt high mechanical efficiency and small chain tension and with chains equipped with latches and protection system for safety and security, this type use double pawl, double guide and are also in the framework style. More safety and hand pull lighter. VT chain hoists are equipped with the most popular block chain--superior grade 80 load chains and forges and heat treated load hooks with batch traceability and stretch indicators, and 360 degree hand rotation with stroke to ratchet indicators. There are also double pawl brake linings, forged safety latch and sealed roller bearings. With fine and beautiful appearance and reasonable structure, they are environmental-friendly with stable operation and durable in use and service. Chain blocks are convenient manual lifting machinery, which are suitable for the short distance lifting of small equipment and goods, and the weight is generally not more than 100 ton. Hand chain hoist shell material is high quality alloy steel, strong wear resistance, high safety performance. VT chain blocks are innovated symmetrical arrayed high speed synchronous gears, and are made of international standard gear steel. Compared with common gears, they are more wearable and steadier, and more laborsaving. The main components are all made of high class alloy steel, with high precision and security. Adopt advanced plastic plating technology inside and outside, it looks like a new one after years of operations. All VT hot chain blocks have safe and reliable braking functions with gear case and hand wheel cover resistant to external shocks and double enclosure to keep out rain water and dust for a long lifespan.
