VEHICLE LOADING CRANES

WARNING! Vehicle stability during operation of any superstructure system is the responsibility of the bodybuilder and the user. The user should at all times make sure that vehicle stability is guaranteed. It is therefore important that clear instructions for use of the

superstructure should be provided by the bodybuilder on or supplied with the vehicle.

For more information see:

1.3: "Verificaton of superstructure"

4.3 VEHICLE LOADING CRANES

The attachment method for a vehicle loading crane depends upon the position of the crane:

- crane immediately behind cab: BAM 2, or - crane at rear end of chassis: BAM 3a. or

BAM 3 (LF and CF65 series)

- crane in combination with more than 2 crane supports: BAM 4.

Consult DAF for any position other than the two above-mentioned crane positions, for instance for cranes mounted amidships.

(1) Position of the crane; crane behind the cab, see Graph A, and crane at the rear overhang, see Graph B.

(2) Dependent of vehicle layout, see chassis drawing.

Attachment of the crane base

The number of attachment bolts under the crane base depends on the attachment method and the maximum capacity of the crane. It should always be determined by and under the responsibility of the supplier of the crane. In any case, the part of the sub-frame on which the vehicle loading crane is to be mounted, must be attached to the chassis frame of the vehicle with large attachment plates and flange bolts.

Sub-frame dimensions

Always use a sub-frame when mounting a crane superstructure on a chassis frame. For the dimensions of the required sub-frame, refer to one of the two graphs shown below. The following information will help you to choose the applicable graph:

The 2 graphs (A and B) can be used to determine the sub-frame dimensions as follows. Graph A:

from a crane capacity of, for instance, 140 kNm, draw an imaginary horizontal line to the right until it crosses the vertical line of the side member, for instance 260x75x6 (LF55). The reading for the sub-frame dimensions is box section 160x80x8.

The dimensions of the chassis members (possibly with flitches) in the indicated critical zones (*; see figure) of the chassis can now be read from the bodybuilders' drawings.

These drawings are available from DAF and they can be found as digital files on the TOPEC CD-ROM and the internet (www.daf.com).

position of the support legs and the structure of the surface under the support legs. Vehicles with front leaf / rear suspension or full air-suspension. During crane operation; deflating the suspension of the vehicle and than lifting the chassis using the crane support legs can lead to damage to the air bellows. Therefore the ECAS air-suspension should be equipped with the function to deflate the air-suspension to low residual pressure to protect the air-bellows. For installation of this function, please contact DAF Sales Engineering.

Vehicle stability during operation of any superstructure system is the responsibility of the bodybuilder and the user. The user should at all times make sure that vehicle stability is guaranteed. It is therefore important that clear instructions for use of the superstructure should be provided on or supplied with the vehicle.

Recovery vehicles and hydraulic platforms The superstructure should always be attached to the chassis with a sub-frame or a self-supporting ("pontoon-type") sub-frame construction. If the latter type is used, it is generally not possible to provide a rigid attachment because of the unequal distribution of strength and stiffness between the chassis and sub-frame and

consequently the location of the neutral line of the assembly. If the vehicle chassis frame has to contribute to the strength of the superstructure, DAF should be contacted.
