Scheduling winch as simple structure, less weight, mobile convenience, and the ground was widely used in mining, metallurgical mines or construction sites, such as dispatching and other transportation work. Winch the main features are: small size and weight of the structure, the rope speed isnot high, installation and removal easy to operate, start balance (stability), the failure rate is low and easy to deal mon fault, and easy maintenance. Many ofour scheduling winches are designed to introduce the former Soviet Union, and on the basis of their made some improvements, the design of the main features: the use of two-winch internal drive and a ary gear transmission. Z1/Z2 and Z3/Z4 for two Internal Drive, Z5, Z6, position of ary transmission mechanism. Installation of the motor shaft head of the extended sets of gear Z1, through the gears Z2, with gear Z3 and Z4, the movement spread to gear Z5, the Z5 is the ary gear wheel ofa central round (or round the sun), Further promote the two ary gear Z6, and the gear Z7. ary gear freely installed in the two driven and connected toa fixed axis, the largest in the gear Z7 Gear work with the external gateway, used to control winch drum operation. In order to achieve good results, are contained in the design of the bodies contained no extra bound to take t
