Safety Parts Requiring Regular Replacement

Warning

Be sure to replace safety parts regularly. Neglecting to replace the safety parts regularly can cause accidents.

Some components of your machine use parts which wear with time. It is not always easy to determine when they should be replaced, even if the periodic inspection is performed as recommended. For safety, such parts must be replaced regularly.The following table gives the replacement intervals for the major safety parts. Contact your nearest TADANO distributor or dealer to have these parts replaced at the regular intervals.

Greasing [NOTICE]

◆ Using different brands of grease together can change the properties of the grease and have an adverse effect on the machine. When you add grease, be sure to use the brand that is in the machine.

If a different brand of grease must be used, take out all the remaining grease before adding the new grease.

◆ Dust in the grease causes premature wear of sliding surfaces, and consequently, shortens the life of the crane. Always clean grease nipples and other surfaces before applying grease. The wire ropes should be cleaned using a wire brush, compressed air, etc., before they are greased.

◆ Lubricating wire ropes with an improper gear oil, cup grease or waste oil only shortens their life. Use rope grease or other grease that has properties suitable for wire ropes.

◆ In addition to the areas listed in the "Maintenance Table", the following areas should also be lubricated with grease to protect them from rusting and ensure smooth movement.

•Hydraulic cylinder rods (boom elevating cylinder, jack cylinder, etc.) that are exposed to air when the cylinder is in a fully retracted position

•Links and sliding sections that were coated with grease before shipment from the factory

Slide Plate (top surface of the boom) (See the Fig. 1.)

1. Extend the outriggers fully and set the crane level.

2. Retract the boom fully and lower it to horizontal.

3. Add grease through the grease nipples.

Slide Plate (bottom surface of the boom) (See the Fig. 2.)

1. Extend the outriggers fully and set the crane level.

2. Extend the boom until the grease nipples on the lower face of the boom are exposed.

3. Add grease through the grease nipples.

Side Surface of Boom, Wire Rope for Telescoping

the Boom (See the Fig. 3.)

1. Extend the outriggers fully and set the crane level.

2. Extend the boom fully and lower it to horizontal.

3. Remove the dust and stains on the exposed portion of the wire rope for boom telescoping and apply grease to the wire rope.

4. Apply grease to the side faces of the boom using a brush.
