TAI donati CLEVER CONVENIENCE ELECTRIC CHAIN HOIST

ELECTRIC CHAIN HOIST DMK SERIES DMK series, the most reliable and safe way to lift loads up to 4.000 kg. The DMK electric hoists with self-braking conical motors, have always been synonymous with quality and reliability. Designed to meet the needs of the international market, they offer a wide range of uses, long-term reliability, safety guarantees during all operating phases and excellent value for money. DMK hoists are also known for the quality of their components, the high technology used to machine mechanical parts, finishing and surface treatments. The special water-repellent...

TROLLEYS The electric chain hoist is generally used to lift un-guided loads, using a hook or handling accessories adequate for the purpose. When the hoist is combined with an electric or manual trolley, which runs on a beam, it ensures combined lifting and horizontal movement of the load. The electric chain hoist and trolleys can be mounted overhead and fitted with monorails or be incorporated and become the completion of other lifting machines such jib cranes, bridge cranes. The electric chain hoist, positioned overhead or on the ground, can also be used in various fixed position...

THE ELECTRIC CHAINHOIST RANGE DMK series electric chain hoists and electric trolleys are manufactured based on a modular component design, assembled together based on commercial needs, and make it possible to quickly and inexpensively create many standardised and special executions; in addition to the standard versions always available in the warehouse. Thanks to the extreme compactness of the basic components, i.e. the motor and gearbox, they are assembled together in a coaxial line, in order to ensure the maximum use of the hook run and minimum encumbrance of the hoist. The construction...

9 THE ELECTRIC CHAIN HOIST RANGE FIXED EXECUTION, ELECTRIC AND HAND-PUSHED TROLLEY EXECUTION, LOW HEADROOM EXECUTION AND "CLIMBING" EXECUTION FIXED EXECUTION: eyebolt suspension or hook suspension (upon request). TROLLEY EXECUTION HAND-PUSHED: horizontal movement by manually pushing the load. ELECTRIC: movement is motorised (one or two speeds) and controlled directly from the hoist push button pendant. CHAIN: horizontal movement by chain controlled by the operator who controls the trolley wheels. LOW HEADROOM EXECUTION: to use the maximum hook run, the hoist is fitted with a chain return...

THE HOIST IN DETAILDESIGN AND CONSTRUCTION 14 1 CHAIN FALL UP TO 2000 kg This is a winning technical solution that offers: more compact design and greater hook run since the bottom block has smaller dimensions compared to a hook block and the chain box is smaller; ^ greater safety for the operator who can touch the hook and chain without the risk of being dragged in and crushed; ► greater reliability, less maintenance and lower operating costs since jamming cannot occur, the chain is not worn by the return and there are no moving parts to replace in the bottom block; ► greater use...

ELECTRICAL CONTROLS When the hoist is supplied with electrical control, the movements can be activated, alternatively, by: low voltage controls at AC 48V - 50Hz, including: the transformer for the low voltage power supply of the control circuits, the general line contactor, the contactors for the control of the hoist and electric trolley motors, transformer protection fuses and terminal block for connections of the auxiliary and power circuits. The components are contained in a sealed box with IP 55 protection, made of shockproof thermoplastic material. The equipment is installed on the...

CRITERIA OF USE AND OPERATING LIMITS donati THE STATE OF STRESS The state of stress is evaluated considering the actual entity of the loads to be lifted and it is ascribable to one of four spectrums of load shown below which determine the type of service. It is necessary to check the parameters which characterise the operating limits of the DMK electric chain hoists to be able to have a complete correspondence between the DMK electric chain hoists and the service they were designed for. These are the actual lifting capacities, which must always be less than or equal with respect to the...

TECHNICAL SPECIFICATIONS AND DATA FOR DMK HOIST CHAIN CLIMBING EXECUTION chain falls capacity hoist Suitable for incorporation into metal poles used for lighting. For assembly and maintenance, relevant chain return allows a mobile crown, fitted with lights, to be lifted and lowered along the pole itself. In order to guarantee excellent operation, the hoist is assembled in an inverted position with respect to standard applications. NOTE: For EM trolleys with electric travel limit switches, check the R dimensions on page 12 * Electric trolleys suitable to run on a bend with guide roller kit
