Mine hoist is one of leading products in our company, which has made great achievements through the continuous exploration and research for more than 40 years in hoist industry field. For the mine hoist industry field, CIC Luoyang Heavy Machinery Co., Ltd. (Namely the original Luoyang Mining Machinery Factory) is equipped with the relatively complete test equipment and methods and has a batch of scientific and technical personnel with strong capability, including national-level specialists, senior engineers, professors, and province-level trans-century excellent technical talents, who are specially engaged in research of the equipment technology and the new product development for single rope winding hoist, multi-rope friction hoist, dam hoist, sinking hoist, pull hoist, anti-explosive winch etc. The company has gained the coal safety certificate of the single rope and multi-rope mine hoist with the diameter of 2m—5m.

I. Function: it is the same with that of JKA single rope winding mine hoist;
II. Mode meaning: it is the same with that of JKA single rope winding mine hoist;
III. Order information: this series is the products designed in 1970s and spare parts are available mainly by the ordering, while JKA type product is recommended for the whole machinery ordering;
Ⅳ. Technical performance sheet:

1. Adopt various coiling blocks of one-blade type, double-blade type and four-blade type
2. Rope groove of coiling block adopts processing spiral rope groove, broken-line rope groove or wooden lining and plastic pressing spiral rope groove, in which transition device is set up in layers
3. Adopt oil cylinder rear-mounted disc brake, the linked control of hydraulic pressure and the electric; The hydraulic station includes two types of medium-low pressure and medium-high pressure. The medium- low pressure hydraulic station includes two braking modes of constant braking force electric delay and two-period braking hydraulic delay. The middle-high pressure hydraulic station includes two types of constant deceleration and constant torque controlled by secondary brake mode. The hydraulic station may be equipped with the pressure sensor and the pressure relay.
4. The main shaft can be connected with the coiling block by the plane friction torque.
5. The signal monitoring device consists of optical-electricity encoder, selsyn and low-speed DC speed-detecting generator set, and has the complete testing protection function for over-speed, over-winding and failure of depth indicators and brake shoe wear and spring fatigue
6. The console includes two types of integral-type and split-type, which adopts integrated signal light, electric instrument with sound performance and new integrated operating handle, and depth indicating system combining of the digital depth indicators and digital and screwed depth indicators as one, and is equipped with specialized table-broad of industrial television or computers and the printers, etc.
7. The head sheave device adopts the one-blade or two-blade welding structure, rolling bearing for supporting, and the friction liner made of polyvinyl chloride or nylon mounted on the flange
8. Internet control and the remote diagnostic system of mine hoist can be equipped.
