II/. PROPER USAGE OF THE HOIST & CRANE - TRUÏC :

HÖÔÙNG DAÃN SÖÛ DUÏNG PA-LAÊNG & CAÀU

The hoist is a machine to lift a heavy load and carry it by use of space. Misuse of the hoist will cause hazardous conditions such as dropping of the lifted load and electric shock. Before operation, be sure to read this instruction manual carefully for proper use. The following are dangers and cautions in using the hoist, which should thoroughly be understood by the person in charge who actually uses the hoist at worksite before use. Pa-laêng laø moät thieát bò maùy duøng ñeå naâng vaät naëng vaø mang chuùng treân khoâng. Söû duïng sai seõ gaây ra nhöõng tình huoáng nguy hieåm nhö rôi taûi naâng vaø chaïm ñieän.

Be sure to perform preoperational inspections and periodic self-inspections.

Perform self-inspection (including yearly self-inspection and monthly self-inspection) for the presence or absence of problems with each part of the crane at fixed intervals. Also, adequately perform preoperational inspection based on the daily check sheet. For performing periodic self-inspection safety and effectively, it is necessary to install inspection workbench(es).

Never lift any load exceeding the rated load.

Tuyeät ñoái khoâng naâng baát kyø vaät naøo quaù taûi.

* Taûi troïng ñöôïc ghi roõ treân moùc naâng taûi.

Care should always be taken so that the working load will not exceed the rated value. Operation under an overload will cause damage to gears, bearings, etc., fatigue of the wire rope, burning of the motor, and other failures, which will shorten the life of the hoist, and may cause a serios accident affecting the lives of people at worst.

Do not lift any load exceeding the rating.

Tuyeät ñoái khoâng ñöôïc ngoài treân taûi naâng. Vaø cuõng khoâng ñöôïc duøng taûi naâng ñeå cöôõi.

A lifted load is unstable, and if anyone attempted to ride, a person may fall, or the load may drop.Do not carry or lift anyone with the crane for working. Doing so will lead to a serious accident.

N.A.G.O.Y.A. MACHINERY CO., LTD

To be ready for a drop, do not operate right under the hoist, and avoid carrying the load over anyone's head. Furthermore, operate the crane as walking along the backing order not to be hit by the swinging load.

Do not leave the operating position with the load lifted.

Khoâng ñöôïc rôøi khoûi vò trí vaän haønh trong luùc taûi ñang ñöôïc naâng.

The on-site person in charge should never allow the crane operator to leave the operating position with the load lifted, and also the operator should not leave the operating position with the load lift. It is very dangerous if any outsiderapproaches the load.

Do not divert your attention from the load during operation.

Khoâng ñöôïc maát taäp truïng khoûi taûi naâng trong thôøi gian vaän haønh.

Do not become distracted when operating the crane, and only operate after checking around to prevent direct and indirect accidents when carrying a load. Also, constantly make efforts to secure safety around the area during operation.

Do not perform such an operation that the load or load block will swing. Khoâng ñöôïc vaän haønh trong tröôøng hôïp vaät taûi hoaëc moùc taûi seõ bò ñaùnh voõng. Being familiar with crane performance and operation, and operating by the following procedures allow for operation with less swinging of the load. Press the east, west, south or north button, and release it for switching off immediately after the hoist & crane start, and press the push button again when the delayed lifted load comes right under the hoist for continuous operation. Doing so allows stable operation with no swinging of the load.

Do not normally use the overwind limit switch for stopping.

Khoâng ñöôïc thöôøng xuyeân söû duïng coâng taéc giôùi haïn treân ñeå ngöøng pa-laêng.

The overwind limit switch is the only switch to prevent accidents by overwinding. Its regular use will cause failures of the limit switch, resulting in a major accident. If it is used to keep the lifting stop position constant, provide an additional limit switch. Never correct the lifting allowance by deforming the over-wind lever for an upper limit.

Avoid oblique pulling.

* Move the hoist right above the load, and then lift it.

Traùnh ñeå pa-laêng keùo leâ taûi naâng.

* Di chuyeån pa-laêng ngay tröôùc khi naâng vaät taûi roài môùi naâng vaät taûi leân.

Properly, the load should be lifted up from right under the hoist. Horizontal pulling is dangerous because the load will swing when it is dynamically lifted off, and also the wire rope is wound in a disorderly fashion on the drum, which will extremely shorten the lift of the wire rope.

When lowering, do not operate exceeding the lower limit.

Khi taûi ñi xuoáng, khoâng ñöôïc vaän haønh vöôït quaù giôùi haïn döôùi.

Operating exceeding the lower limit may cause dropping of the lifted load because two or more dead turns of the rope cannot be secured, which increases the tension of the end of the wire rope, so that the end of the wire rope will break.
