What will be the maximum loading capacity? 2. What will be the maximum lifting height? 3. What hoisting speed is to be employed?. Will an auxiliary reduced lifting speed be required?. What will the operational conditions be?. What will the travelling speed be, if required?. How do you need to operate the hoists? The type of the hoists is to be defined in accdance with the load spectrum, the average operating time per day in hours, the loading capacity and the reeving. 9 % operating time GROUP DIN / FEM 9.

8 Description of the electric hoist Hoisting mot Electric mot with conical rot and conical stat as well as asbestos free conical brake. Easy axial moving possibility of the rot. Reliable brake activation from spiral spring impact in case of electric power breakdown. Creep speed of the mot. The wide range combinations of mots and gear units expand the range of available goods and lifting speeds. Gear unit Twostage heliocentric gear unit assembled to opposite side of the mot. High quality materials are used. Suitable hardening and grinding of gear wheels teeth surfaces ensures their long life, iseless operation and high coefficient of gear unit's efficiency. Drum Equipped with helical grooves f the wire rope and efficacious rope guide, which ensures reliable arrangement of the rope in drum's grooves. The front mot flange by means of ball bearing suppts one of the drum's diaphragms. The tque from the gear unit to the second drum's diaphragm is transmitted through grooved hollow shaft. Rope guide New made construction. No special tools are required f the replacement of the rope guide. Ensures precise rope winding and unwinding. Possibility f rope deviation ±. Actuates the end limit switch in upper and bottom position of the hook. Blockhook The block hook and the purchase block are entirely new constructions, cresponding to the modern technical safety requirements. Ensures easy operation with minimum dead weight. Protection against the rope getting out of the rope rolls is also ensured. Body The body is completely new construction in box fm. Represents a robust welded construction as a flange connection between the mot and gear unit. Wire rope's outlet in all possible radial directions permits the realization of different assembly versions and positions. Rubber packed coupler This is flexible coupler as a joint unit between the hoisting mot and gear unit. The coupler wks as a shock absber and ensures resistance free mot's shaft axial replacement. Sure connection between the mot and the gear unit is warranted. 9 Balkancarpodem Ltd. All rights reserved. Trolleys Three types of trolleys are available: mail trolley with standard headroom, mail trolley with reduced headroom and double rail trolley. The hoist is hanged up mounted to the trolley in the best position, ensuring optimum load distribution on the travel wheels. The trolley could be also electric, hand geared push travel. Drive unit the same type as a main unit of the hoist powers the electric trolley. Nmal drive unit with electromagnetic brake is available. The traveling speeds are in very wide range. Stage less fitness in accdance with the width of the mail traveling track is submitted to crect wk of the trolleys. In case of double rail trolley the purchaser gives the rail's distance. Electric equipment Power circuit voltage and frequency are at purchaser's request. Control voltage to relays and contacts is 2V, frequency and Hz. The most part of electric equipment is assembled in command box, fastened to the body to other appropriate part. Terminal box of the mot holds end limit switch.
