HSC chain blocks

HSC chain blocks also named HS-C series chain blocks, which have advanced technology in the form of HS-Z hand chain blocks. HSC chain blocks are the kind of widely used and portable manual operating hoisting machine, and they are very suitable to be used in the open air and the place without power. HSC chain blocks are suitable for short distance lifting of small equipment and cargo, and the lifting weight is generally no more than 100T. The work principle of HSC chain blocks is that by dragging the chain and sprocket, the chain pulley and brake base are pressed together and rotated together, then the long tooth shaft turns the blade gear, short tooth and spline gear. In this way, the sprocket installed on the spline gear drives the chain which can lift loads stably. Adopting single ratchet friction disc brake, which can brake by itself under load. Under the action of spring, the ratchet pawl meshes with the ratchet wheel to make sure brake work safely. The panel of HSC chain blocks adopt advanced technology of electrophoresis which offers more pretty appearance than the traditional blackening ones, and it works more close with the cover. The covers of nameplate and hand wheel are both made of 1.5mm material, which is thicker than the normal way of 0.8mm-1.0mm material. The guide wheel is fully steel forged, which can provide a long service life to our blocks. Compact inner structure is also one of the advantages of our products. Besides, the left and right wall plate adopt integral roller bearing, and the force is even during the test drawing. The new designed upper hook and lower hook adopt the famous brand, which covers the shortage of the More details pls visit our website: http://www.ramhoist.com/ Or send to info@ramhoist.com
