Electric wire rope hoist

electric cable hoist, reliable braking effect of a good winch brakes, in the United tooth plate (2) at the center of a hollow gear interlock (1), the United tooth plate on top of the cloth were associated with a circumferential three ledges and three circumferentially equally spaced pivot pin (3), associated with the tooth plate side provided with a central angular aperture (52) of the airfoil star-wheel (5) the opening of the rail groove (51) sets of valves disposed on said wing thereof stop pin (4), with three brake blocks (6) of the shaft pin hole (61) into the shaft sleeve pin (3), brake blocks at one end with an opening slot (62), the wing airfoil valves located in a part of the star wheel open slot (62), provided with a pin (7) cross-linked to the opening slot groove wall located on both sides of the track groove airfoil star wheel (51) within the outer brake blocks with radial arc convex, brake blocks opening slot the bottom has a blind hole has its built-in spring this spring abuts the outer end of the airfoil wing star wheel side valves, brake blocks on top of a bezel (8) and stop pin (4) and the axle pin (3) the upper riveting. The utility model is suitable for electric winch brakes.

Mine hoisting equipment

Mine hoist lifting equipment is the leading mine equipment , and is currently the most widely used to enhance the liftech electric cable hoist mechanical , so learn the basis of this chapter is to learn the other chapters . This chapter should focus on master :
( 1 ) different types of hoist works, type , scope ;
 ( 2 ) The main components of the hoist structure, liftech cheap wire rope hoist working principle and maintenance points ;
( 3 ) calculate the braking torque calculation and selection of mine hoist .
