CKD AV30 wrecker & rescue crane on Mercedes Benz chassis     

The AV 30 multi-purpose rescue crane is the novelty in branch of rescue technology. There are used long-term experiences of our firm during mobile crane production and there are conserved the qualities for classic crane works, which are extended about the ability for wrecking works of damaged vehicles (winch RAMSEY RPH 45 000 with rope draught 20 t) and for towing of damaged vehicles (hydraulic towing attachment up to the maximum weight 7 weight 7,5 t).
Alternatively the crane can be equipped with further winch HYK 10 with rope guider and stroke 10,0 t in rope¸ 16 mm with length ca 70 m. In front part of vehicle under bumper there can be mounted 3rd rescue winch HV 12/15000 with stroke in rope ca 6,0 t.

TECHNICAL FEATURES
The undercarriage and bottom frame of crane
The crane superstructure is mounted on the chassis Mercedes-Benz Actros 4143 K 8x4 or Actros 4150 K 8x8 chassis, alternatively on chassis TATRA 815 260 R 81 36 255 8x8.2/20. Used chassis has got two rear axles with two-mounting of wheels. The tire size is 315/80-R 22,5, front axles 385/65-R 22,5. There are used two couples of constructively different outriggers for crane stability with considerable extended applied qualities. The first couple of horizontal extending outriggers is placed behind wheels of the second front axle; after extension into working position the vertical cylinders of outriggers are after lowering on land automatically hydraulically locked up. The second couple is placed on the rear end. These outriggers are determined for crane anchorage during wrecking (two-stage outrigger lugs enable using both on paved ground - and digging in ground during wrecking in rough terrain. An optical-acoustic warning device, flashing type, is located on the chassis cabin. The cabin has holders for two breathing apparatus. The crane chassis has several storage spaces for necessary machine equipment and rigging equipment.

Slewing and crane cab, boom
Slewing, operating, cab and crane cover are constructed so that crane abilities of machine would be conserved. There are used electronic overload indicator SLI 05 and high voltage indicator IVN. The boom has got two hydraulic telescopic sections and last one (the fourth) is extended by changing the fixing piston rod pins. The boom length is constructed so that the parameters for vehicle wrecking from shorter distances would be maximally increased. The crane is equipped with pulley block with three sheaves up to maximum weight of 30 t. The truck mounted crane is possible to be equipped with the hydraulics DANFOSS with proportional joysticks of crane functions as required by a customer.

Wrecking mechanism
Own wrecking mechanism consists of twice break, hydraulic operated jib with zinc wrecking and transport fork. The jib is completed with hydraulic winch RAMSEY RPH 45000 with rope draught 20 t. The winch is equipped with rope of length 70 m, and therefore is possible to get out the vehicles from distances longer than 60 m. The winch construction makes possible a rope lifting with manual traction force without necessity of hydraulic unwinding (higher speed during using). The hydraulics of wrecking jib and winch operating is remote controlled, by the means of transmitter and it makes for staff possible to control wrecking works from immediate nearness. During road transport of crane the wrecking fork is lifted in safety height next to boom and therefore it is not able to endanger other vehicles in any case. The fork is in this position locked mechanically. The fork is adjustable both for different wheel pitch of towing vehicles and also makes possible the change of crane radius behind the rescue crane (telescopic, hydraulically extended jib). During lifting of towing vehicle by the fork the hydraulic locks of lifting rollers are locked up and the fork is so arrested for transport. The lifting capacity of the fork is 7,5 t. The crane is equipped with an electronic scale to determine the weight of the load suspended on the transport (winching) tackle..

The change of construction possible!
* If the scrapper blade is mounted, there is no winch HV 12/15 000

Scrapper blade
The crane can be completed as special equipment with hydraulic scrapper blade - type PSS 26 with width 2600 mm. The snow-plough blade is adjustable hydraulically both in vertical and horizontal level (it is able to adjust it in inclined level to both sides of vehicle). All manipulation with blade is very easy and it is made from panel placed in driver cab of vehicle. The blade is possible to assembly and disassemble from vehicle very easy, inclusive of disconnecting of hydraulic controlling by help of quick couplers. Lower edge of blade is covered by rubber.

Special equipment
The crane is possible to be equipped with further equipment according to specific requirements of customer like is for example extending of tools equipment and special preparations, further headlights (e.g. point rotating one for night seeking, or lighting of damaged vehicle), etc. The crane is equipped with long-distance controlled reflector for lighting of working site placed on first telescopic part of boom reflector is possible to move round in any direction by help of operating device.

Delivery term and payment conditions
The crane with regard to its specific use is not made serially, but only made-to-order. Therefore delivery time is s about 6 months after signing the contract. Payment conditions will be determined according to agreement. But advance payment to the amount of 40 % of contract price is supposed to be paid. Price and payment conditions for export are in need to specialize for every factual order independently (influence of required delivery conditions, machine’s equipment, distance of delivery place, etc.).

Guarantee and after-guarantee service
All guarantee and after-guarantee service of crane is made by producer or its authorized service stations except of such crane parts, the repairs of which are subject to repair of relevant producer (e.g. in its network, electronic device, etc.). The length of guarantee time is given standard 12 months since the date of the sale to the final user in accordance with conditions fixed in guarantee letter.
