The working principle of 2T chain block

The working principle of 2T chain block

The 2T chain block is actually an upgraded version of the fixed pulley, which not only has the advantages of fixed pulleys, but also the symmetrical arrangement of the secondary spur gear rotation structure due to the combination of the reducer and the chain pulley block with reverse back brake. It is simpler, more durable and more efficient in practical applications.

The working principle of the 2 ton chain hoist is mainly: by rotating the manual chain and the rotation of the bracelet wheel, the friction plate ratchet and the brake seat are pressed together to rotate together, and the long shaft of the tooth rotates the plate gear, the short shaft and the spline. Hole gear. Thus, the hoisting sprocket of the device on the spline hole gear drives the hoisting chain and smoothly lifts the weight. The ratchet friction plate type one-way brake can brake itself under load, and the pawl meshes with the ratchet under the action of the spring, and the brake works safely.

It should be noted that it is necessary to wait until the heavy objects are safely landed before the 2 ton chain hoist can be removed. After use, gently handle, put it in a dry, ventilated place, and apply the lubricating oil.
