EVERDIGM Core Drill Rig ECR12 & ECR18. Operation and Maintenance Manual (2016.02.27) - page 2

2.5. Information for ordering parts and service

IMPORTANT!

Parts may subject to changed for improvement. It is highly recommended ordering parts with

equipment serial number.

Using non-genuine or improper parts may cause shorten equipment parts life, or serious

damages on related parts.

The machine serial number is marked with the type and serial number on the nameplate. It is important to

make correct reference to the serial number of the equipment when making repairs or ordering spare parts.

Identification by serial number is the only proper means of maintaining and identifying parts for specific

machine.

3. Towing, lifting and transporting method

DANGER!

Follow local road safety regulations on weight, width and height limits. (Transporting)

Check strength of wire and hook condition and weight capacity before towing and lifting

equipment.

Do not stay inside of cabin or operate equipment while it is towed, lifted and moved by trailer.

3.1 Towing

① Before releasing brake, the equipment should be stand on flat ground, or supported firmly with high

strength wires on uneven ground.

② Dismantle plug from travel motor.

③ Dismantle cover plate from travel motor.

④ Remove drive gear from inside of travel motor.

④ Assemble and tighten cover plate and plug.

52

▶ Hook points

< Rear Side >

▶ Note

: Hook point location or shape may different according to core drill model.

: After towing, replace gear oil as describes "5.4.10 Travel motor oil replacement".

53

3.2. Lifting

Incorrect

Correct

• Wires and blocks which support the machine should be strong to lift it.

• Mast should be folded and firmly settled on the supporter. No movement of mast is allowed.

• Wires should not touch mast or bonnet during lifting procedure.

• Do not wind wire on hook. Wire should be securely hold.

54

3.3. Transportation

 Guideline for transportation

① Fold mast, and set the mast to horizontal position.

② Mast should be firmly settled on the supporter above the frame. If possible, tied up the mast with

supporter and trailer.

③ Tied up equipment with trailer bed correctly.

3

 Loading and unloading on trailer

① Width of trailer should be wider than equipment track.

② Pay special attention for driving when the equipment is loaded on the trailer.

③ Fix ramps on the trailer tightly, and angle of slope need to be less than 15 degree from ground.

Pay attention on ground condition while it is moving. Do not attempt to move the machine

where danger situation is predicted.

Pay special attention to your feet while machine is moving.

82

4.4.2 Correct posture for moving equipment

 Machine posture before moving

Fold upper mast with lower mast and put the mast on the supporter firmly. Mast and related parts

should not move freely on uneven ground while machine is traveling.

Check ground condition where the machine will move.

 Do not carry heavy object with machine

Carrying heavy objects will break down the balance of machine, and cause damage or deformation of

components.

83

 Do not move machine with mast in the air while traveling

External shock or bending stress will cause damage to the machine.

 Pay special attention while traveling narrow area

The slope and ground may not be strong enough to support machine. Check track location while

driving narrow area.

84

 During operation

Do not support machine or press mast with excessive force. It will cause damages to the machine.

The machine should be securely supported with 4 outriggers during operation. The outriggers should

be settled on the strong and firm ground.

85

4.5. Controller and switches

DANGER!

Do not allow others to approach to the machine while it is operating.

Wear ear plug, safety helmet, mask and safety glass for your safety. High noise during drilling

can hurt your hearing, and rock powder will be very harmful to your health.

Pay attention to the moving parts. It may hit machine or other objects.

 Diamond core bit condition check

Check wear condition of tip on the bit before using it. Tips or bit are damaged or worn out badly,

replace it with new one.

Figure: Diamond core bit wear check

90

 Wear or damages of steel rope

Check steel rope condition, and replace it if it is damaged as shown following examples.

Wire displacement

Individual wires or wire groups stick out like hairpins on the side facing away from the drum. Wire

displacement is caused by spasmodic loads.

Ropes with wire displacement must be scrapped.

Figure: Example of wire displacement

Waviness

Waviness is a deformation that gives the rope's longitudinal axis a helical curve. Even though wave

formation does not necessarily cause weakening of the rope, such a deformation can cause a pulsing

movement.

After a long time of operation, this can increase surface wear and wire breaks. In the event of

waviness, the rope should be scrapped if

d ₁

> 4d/3

d = Rope's nominal diameter

d ₁

= Diameter of the circle that would be formed if the rope were not deformed. Check over a length

not exceeding 25d.

Figure: Waviness

91

Cracks

Cracks are deformations through outer, violent influences. Ropes with cracks must be scrapped.

Figure: Cracks

Kinks

A kink is a deformation caused by the rope forming an eye that is contracted with out the rope being

able to rotate around its own axle.

Strand pitch is altered, which leads a great deal of surface wear and, in severe cases, very low static

strength.

Ropes with kinks must be scrapped.

Figure: Kinks

Flattening

Flattening is deformation caused by mechanical damage. Ropes with severe flattening must be

scrapped.

Figure: Flattening

92

Local rope diameter decrease

Local decrease in rope diameter is often connected to core break.

The area near the end attachments must be inspected especially carefully as it can be difficult to

detect rope diameter decrease at these spots.

Ropes with severe rope diameter decrease must be scrapped.

Figure: Local rope diameter decrease

Local rope diameter increase

This means repeated thickening of the rope over a long stretch. At the thicker spots, the core pushes

out of the rope and causes unevenness of the outer strands.

Ropes with severe rope diameter increase must be scrapped.

Figure: Local rope diameter increase

Basket formation

Basket formation occurs on ropes with steel reinforcement or steel core when the outer strand layer

becomes longer than the inner strand layer.

Basket formation can also be caused by shock loads on slack ropes. Ropes with basket formation

must be scrapped.

Figure: Basket formation
