DMK Electric Chain Hoists The DMK electric chain hoists and related electric trolleys are produced according to the design of modular components which, assembled together in relation to commercial needs, as well as the standard versions available in the warehouse, allow various standardized and special executions to be carried out rapidly and economically. The DMK series electric chain hoists can be used in fixed execution (hook or eye) with hand-pushed trolley, electric trolley, trolley in low headroom configuration also in climbing execution. The basic components, motor and reduction gear, thanks to their extreme compactness are assembled together in coaxial line, to ensure maximum use of the hook run and minimum headroom of the hoist body. The manufacturer uses the most advanced technology based on production processes of high industrialization and allows the realization, by economies of scale, of totally reliable and technically innovative machines. A high level of quality is guaranteed and checked by the company quality control system according to standard UNI EN ISO 9001: 2000. The range of DMK electric chain hoists series is produced in: 4 basic sizes: DMK 1-2-3-4 , with capacities from 100 to 4000 kg, in the FEM (ISO) service units - 1Bm (M3), 1Am (M4), 2m (M5). single lifting speed: made with a 4 pole motor : 4 or 6,3 or 8 or 16 m/min. for Single chain fall hoists; 2,5 or 3,2 or 4 m/min. for Dual chain fall hoists. two lifting speeds : made with pole change motors : 4/1,2 or 8/2,5 m/min. for Single chain fall hoists; 2,5/0,8 or 3,2/1 m/min. for Dual chain fall hoists standard hook runs: 3 mts. (different lifting heights available on request) 1 chain fall up to 2000 kg A technical innovative solution which provides: * reduced headroom and a bigger hook-run as the single fall hookblock is of smaller dimensions than a two falls one, the chain collector is also smaller * greater safety for the operator who can touch the hook and the chain without danger of being dragged along or crushed * greater reliability, reduced maintenance and lower working costs because the chain cannot jam, there is not wear by the return and in the lower block there are no moving parts to replace * greater flexibility of use 2 chain falls up to 4000 kg A cost-effective solution in terms of the whole system which: * offers a fixed anchorage point to which an overload device is fixed suited for heavy applications thereby avoiding the need to over dimension the structures of support * keep the headroom of the hoist and the cost of the chain low. Protection and insulation of electrical parts: * Self braking lifting and travelling motors: Protection IP55 - Insulation class "F" * Limit switch: Minimum protection IP65 - Maximum insulation voltage 500 V * Cables: CEI 20/22 II - Maximum insulation voltage 450-750 V * Protections and insulations different from standard are available on request. Electrical power supply: The DMK electric chain hoists are designed to be powered with alternate current with: * three-phase voltage of 400 V - 50 Hz. according to IEC 38-1. * single-phase voltage of 230 V +/- 5% - 50Hz. (for DMK hoists 1 - 2 - 3, at one speed and capacity up to 800 kg). * Voltage and frequency different from standard are available on request. Nominal conditions of use in standard execution: * Temperature of use: minimum - 10° C; maximum +40° C. * Maximum relative humidity: 80% * Maximum altitude 1000 m above sea level. * The machine must be placed indoors, in a well-ventilated place free of corrosive vapours (acid vapours, saline mist, etc). * Special executions, for different environmental conditions or for outdoor use are available on request. Noise * The level of acoustic pressure emitted by the hoist at full load is always less than a level of 85dB (A). The incidence of environmental characteristics such as sound transmission from the ground through metallic structures, reflections caused by combined machines and walls is not included in the level indicated.
