RUD VCGH Bolt on Excavator Hook

Dimensional Drawing

Bolt-on Excavator Hook - RUD VCGH.

Excavator hook used as a lifting point for wire rope slings, round slings and lifting means with an oval suspension ring or eye. With a stable hook securing mechanism comparable to that of the VCGH.
Min. bolt quality is 8.8. Only the provided crack detected bolts should be used.
The surface is pink powder coated.
Pay attention to the permissible load direction.
Work piece material, at least 1.0037 (St 37).
For leight metals, nonferrous heavy metals and grey cast iron, the thread type allocation must be done in such a way that, the WLL of the thread type fulfils the requirements of the respective work piece.Make sure the bolting surface is plain.
Ensure an appropriate bore depth to facilitate an optimal sitting of the engaging surface. Tighten up the bolts with a torque of 800 Nm.
When impact loaded or operated in environments with vibrations, unintentional loosening can happen, especially if through bolts with nuts are used.
Securing possibilities: Tighten the bolts with the specified torque and use a liquid thread securing medium eg. Loctite ( adapted to the respective requirements, follow the manufacturer`s recomendations).

Bolt on Hook suitable for wire rope, chain and round slings.

Ideal for incorporating into lifting beam assemblies.

User Instructions

1. Reference should be made to German Standards accord. BGR 500 or other country specific statutory regulations and inspections are to be carried out by competent persons only.

2. Before installing and every use, visually inspect RUD lifting points, paying particular attention to any evidence of corrosion, wear and weld cracks and deformations. Please ensure compatibility of bolt thread and tapped hole.

3. The material construction to which the lifting point will be attached should be of adequate strength to withstand forces during lifting without deformation. The German testing authority, BG, recommends the following minimum bolt lengths:

• 1 x M in steel (minimum quality S235JR [1.0037])
• 1.25 x M in cast iron (for example GG 25)
• 2 x M in aluminium alloys
• 2.5 x M in aluminium-magnesium alloys
• (M = diameter of RUD lifting point bolt, for ex. M 20)

When lifting light metals, nonferrous heavy metals and gray cast iron, the thread has to be chosen in such a way that the working load limit of the thread corresponds to the requirements of the respective base material.
RUD excavator hooks are delivered with 100 % crack tested bolts. When using your own bolts, the bolts have to be 100% crack tested. The min quality of the hexagon bolt had to be 10.9 accord. EN 24014 (DIN 931) with the nominal diameter.

4. The lifting points must be positioned on the load in such a way that movement is avoided during lifting.
a.) For single leg lifts, the lifting point should be vertically above the centre of gravity of the load.
b.) For two leg lifts, the lifting points must be equidistant to/or above the centre of gravity of the load.
c.) For three and four leg lifts, the lifting points should be arranged symmetrically around the centre of gravity in the same plane, if possible.

5. Load Symmetry:
The working load limit of individual RUD lifting points are calculated using the following formula and are based on symmetrical loading:

The calculation of load bearing legs is as follows:

(See Table 1)

6. A Plane bolting surface must be guaranteed. The holes must be drilled with a sufficient depth in order to guarantee compatibility with the supporting surface. The bolts should be tightened with torque according to table 2.

7. The installation should be in the direction of pull.

Possible use area: (see fig. 1)

8. To prevent unintended dismounting through shock loading, rotation or vibration, thread locking fluid such as Loctite (depending on the application, please pay attention to the manufacturer's instruction) could be used to secure the bolt, or use form-closed devices.

9. All fittings connected to the VCGH-G should be free moving.
When connecting and disconnecting the lifting means (sling chain), pinches and impacts should be avoided. Damage of the lifting means caused by sharp edges should be avoided as well.

A non-adherence to this advice may result damages of persons and materials

10. Effects of temperature:
Due to the DIN/EN bolts that are used with the VCGH-G the working load limit should be reduced accordingly:
-20° to 100°C = no reduction (-4°F to 212°F)
100° to 200°C = minus 15% (212°F to 392°F)
200° to 250°C = minus 20% (392°F to 482°F)
250° to 350°C = minus 25% (482°F to 662°F)
Temperatures above 350°C (662°F) are not permitted.

11. RUD-Lifting points must not be used under chemical influences such as acids, alkaline solutions and vapours e.g. in pickling baths or hot dip galvanising plants. If this cannot be avoided, please contact the manufacturer indicating the concentration, period of penetration and temperature of use.

12. The places where the lifting points are fixed should be marked with colour.

13. After fitting, an annual inspection, or sooner if conditions dicate, should be undertaken by a competent person examining the continued suitability. Also after damage and special occurrences.

Inspection criteria concerning paragraphs 2 and 13:

• Ensure correct bolt and nut size, quality and length.
• Ensure compatibility of bolt thread and tapped hole - control of the torque
• The lifting point should be complete.
• The excavator hook has to be mounted on plane bolting surfaces with the full side.
• The working load limit and manufacturers stamp should be clearly visible.
• Deformation of the component parts such as body and bolt.
• Mechanical damage, such as notches, particularly in high stress areas.
• Wear should be no more than 10%
• Opening of the mouth is deformed more than 10%
• Evidence of corrosion.
• Evidence of cracks.
