The resins must be prepared observing the proportions and times indicated by the manufacturer. Handle these resins with care and avoid all direct contact with the skin. Store the ingredients in a cool dry place. 1) Unscrew the joint from position (1) and place it in position (2).
23 PREPARATION OF RESIN MIXTURE FOR “A” TYPE CABLE GLANDS Warning! To prevent resin from hardening inside the mixing nozzle (max. 15 minutes), make sure all cable glands are ready for sealing.
24 ELECTRIC COMPONENTS MOTORS The different types of motor on cranes and hoists are all provided with six-stud terminal boards. Single-speed motors have terminal boards fitted for star or delta connections. Double-speed motors are fitted only for the nominal voltage required; three terminals are used for low speeds and the other for high speeds. Terminal arrangement is given on each motor rating plate.
25 CONTROL GEAR A metal panel contains all the electric equipment for the starting, protection and control of the motors. Auxiliary voltage is supplied via a transformer which is kept constantly connected. When required, auxiliary protection can be provided by means of fuses and protections of suitable capacity on the main currents to the motors. Control equipment, inside its case, requires periodic maintenance.
26 PRE ERECTION VERIFICATION • • • • • • • • • • • • • • • • Check that no damage has occurred to the various parts of the machine during transportation. Pay particular attention to the rope, push-button control panel and its cable, limit switches, and electric connection cables. Check that the voltage indicated on the hoists data plate and on those on the motors corresponds to the rate power available.
27 SERPES LINE WITH “ZECCA” SYSTEM SUSPENSION The raceway on which the suspension trolleys of festoon lines travel, is supported by brackets which are attached to the upper rim of the crane’s girder (see Pict. 1) Brackets are secured to the girder by means of a “ZECCA” clamp system the rigid connection of which is granted by friction, thanks to two wedges assembled by means of one single screw.

30 “YOYO” ELECTRIC CHAIN HOISTS Electric chain hoist of the YOYO range and the relevant electric traveling trolleys are manufactured according to the concept of modular components which allow the production of different executions, both standard and special. Base components, motor and reducer, thanks to their extreme compactness are assembled to one another on a coaxial line, so as to guarantee the maximum exploitation of the hook’s path as well as the hoist’s minimum overall dimensions.
31 STANDARD EXECUTIONS YOYO hoist’s flexibility of use allows for 5 standard executions. EXECUTION WITH ELECTRIC TROLLEY: (E) it is used for heavy service or when the load can not be pushed by hand; traveling is guaranteed by the trolley to which the hoist is secured, which is controlled by the hoist’s push button control panel. E FIXED EXECUTION (F) the hoist is suspended by means of a support (Fs) or of a hook.
32 DESCRIPTION OF MAIN COMPONENTS (see picture 1 for references) HOISTING AND TRAVELING ELECTRIC MOTOR (1-8) Three-phase asynchronous, designed for S3 intermittent duty, executed in compliance with European rules and regulations. Closed mechanical protection so as to prevent dust and water from entering, wherever they may come from. Flange-mounted application (B5 shape), on the outside of the hoist, therefore it benefits from a perfect cooling thanks to the frame’s fins.
33 LOADING HOOK (7) Made of high grade steel, it is equipped with a safety device (spring catch) against accidental unhooking of the load [RES. 4.1.2.6. e – Enclosure I Machinery Directive] and revolves on a thrust bearing. HOOK TACKLE (single fall hoists) (7) It connects the chain to the revolving hook.

66 SAFETY RULES FOR CRANE OPERATORS • • • • • • • • • • Only qualified crane operators shall use the crane. Before beginning work make sure that runways are clear. Check limit switches and inform the Section Head immediately if there are any problems. Never lift loads exceeding maximum capacity or not properly slinged. Consult data given on the crane. Never start operating until starting signal is given, by the operators assistant or rigger. Do not swing the load.
67 SAFETY RULES FOR LOAD SLINGING Given the ever increasing use of hoisting equipment for handling materials, the issue of load slinging is becoming more and more important. The personnel members employed in such operations must be informed of the specific hazards to which they are exposed or to which they may expose other workers. Loads which can be connected directly to the hook of a hoisting machine are rare. Flexible means such as chains, wire or textile ropes, are used in most cases.
68 Wire rod ties, which hold bundles of bars or pipes, must not be used to hoist those same bundles. Once the load is slinged, check its balancing by slowly hoisting the load by a few centimeters. The suspended load must never be guided by hand, but only with ropes or hooks.

71 INSTRUCTIONS FOR MAINTAINING MACHINES IN GOOD RUNNING ORDER WHEN INOPERATIVE When, due to particular applications, service is irregular or perhaps the machine remain inoperative and stationary in an especially aggressive area the follow measures should be taken: • • • Put the machine through all its movements every day, completing at least 3 working cycles, even with no load. Check the condition of the limit switches every 15 days.
72 Hoists (1) (2) (3) (4) Clean shafts, joints and other exposed machined surfaces using solvent and coat them with an anti-rust product. Keep bearings greased if they are not of the “life lubricated” kind. Clean loading chains and steel wire ropes and coat them with a suitable lubricant. Lubricate pulleys, pinions and sprockets applying grease on their teeth and grooves.
73 VERIFICATION OF THE EFFICIENCY OF BUFFERS • • Check that end stops are not deformed and that they are firmly secured to the structures and that the buffer is intact and well secured to its support. Replace buffers when they show: signs of breaking or of permanent deformation, cuts, abrasions, incisions.
74 in the event a new setting of the load limiter is needed, such operation must be performed by Italkrane s.r.l. technical assistance or by personnel authorized by Italkrane s.r.l.
