Chain Crane Has High Safety Performance

Aug 23, 2017

Chain crane: also known as the gods gourd, not falling, hand chain hoist, is a simple to use, easy to carry manual lifting machinery, also known as "chain hoist" or "down chain." It is suitable for small equipment and cargo short-distance lifting, from the general weight of not more than 100T. Hand chain hoist shell material is high quality alloy steel, strong wear resistance, high safety performance.

There are many types of chain cranes, Chain Hoist there are four types of differential, turbine worm, planetary cycloidal and planetary gears.

Chain cranes include industry-specific features such as sleek fuselage with no sharp edges, embedded handles, grease-filled gearboxes, black canvas zipper containers, plug-and-play transformers (capable of achieving 208-230V / 460 -360v between the easy conversion) and the world famous pull rotor motor brakes, Chain Hoist regardless of wear conditions, have a 5-year warranty period. The crane complies with the German BGV-D8 regulations and the standard configuration complies with the requirements of the CE Declaration. TNER also has industry-recognized speed, Chain Hoist suitable for standard road conditions, and can provide half a ton, 1 ton and 2 tons of lifting capacity.

Additional features of the chain crane also include a unique chain guide that provides a quiet and smooth guide for the chain used in standard (reverse) or reversible configurations, and the upper and lower paddle limit switches provide maximum travel and The carbon friction clutch ensures consistent performance.

The chain crane has an overload protection device that ensures easy adjustment of the maximum lifting load.

The chained crane is conveyed by a rotational drive force generated by the handwheel to a pressurized drive member which is screwed onto a drive shaft in a manner that can be moved back and forth, Chain Hoist through a stop wheel and a pair The friction members on opposite sides of the return wheel are pressed by the pressurizing drive member to the pressure receiving member firmly fixed to the drive shaft so as to be rotated.

Heretofore, a typical overload protection device used in such a lifting device has a structure in which a sliding force is generated by friction between the members when the suspension is likely to be overloaded, Chain Hoist so that the rotational force generated by the hand wheel To a pressurized drive.

In the conventional structure, for example, in the case of a friction plate, when the pressure is adjusted to adjust the limit load, it is particularly time consuming to adjust the pressure on the friction plate. In addition, even if the wear in the use of the process is very small, Chain Hoist but the friction plate wear is still inevitable, the ultimate load will change. In order to avoid this, the pressure must be adjusted in the appropriate way.
