The G-BKF is designed to be able to rescue and tow the new generation of armoured command and control (C2) vehicles, armoured transport vehicles, MULTI FSA (swap body vehicles), and wheeled vehicles that are currently in use whilst the operating personnel is being guarded. The G-BKF is also capable of providing tactical infantry cover over long distances, providing repair and handling support and of rescue, recovery and emergency aid deployments.

High Passenger Protection RequirementsThe main focus upon order placement was on the protection of passengers. To meet the high requirements in this respect, Liebherr works with Rheinmetall Defence, to produce the armoured drivers cab and armoured crane cab. The armoured drivers cab was extended by 250mm compared to the standard Liebherr drivers cab to provide storage space for the extensive personal protective equipment for the vehicle crew and integrate the military communication equipment.
The armoured drivers cab is a double-thickness steel bulkhead construction. The transparent armour has been enhanced to ensure that it offers ballistic protection and meets the visibility requirements of the Road Traffic Act. The protection has been verified to STANAG 4569/ AEP 55. The crane cab is also armoured and is a composite construction to reduce weight. The composite panels are made using a special design and bolted to a steel bearing structure.
Crane Chassis Similar to Standard VersionThe armoured G-BKF rescue crane vehicle is mounted on a 4-axle all-terrain crane chassis (8x8x8), which is similar to the standard version. Despite its weight and size it has excellent off-road properties and manoeuvrability as a result of its large tyres, all-wheel drive and all-wheel steering. The speed-dependent rear axle steering with its 5 steering programs ensures high track stability at high speeds and maximum manoeuvrability. The use of Liebherr's own "D946TI" diesel engine which develops 400kW (544bhp) with the ZF TC-Tronic gearbox with converter and 12 forwards gears and two reverse gears provides plenty of power for towing operations.
Variable Towing and Rescue Modes
In towing mode vehicles up to a load of 16t can be mounted on the lift cradle of the underlift for towing. Military vehicles can be attached to STANAG eyelets using special adapters. Extensive range of accessories means that almost all German Army wheeled vehicles can be towed.
There are two Rotzler Treibmatik winches with tensile forces of 20 kN and 80kN mounted on the rear of the vehicle. These tensile forces can be doubled by using return rollers. The use of both rescue winches together, connected using a control desk, provides a wide range of variations for a massive range of rescue operations. The smaller winch can be moved to the front using the vehicle's own crane for self-rescue purposes. The chassis is fitted with rescue jacks for rescuing a damaged vehicle from difficult terrain.
The rope of the hoist winch over the retracted telescopic boom and the rope of the 200kN rescue winch means that synchronous winching is possible. This means that the damaged vehicle can be raised slightly whilst being pulled by the towing equipment at the same time.
VersatileThe G-BKF is fitted with a 20.9 m telescopic boom with which it can handle loads of up to 20 tonnes quickly and precisely. That means that the G-BKF is not only suitable for rescue deployments but it can also be used as a mobile crane for medium crane work.
All the crane's control functions, the towing device, the two rescue winches and the jacks can be operated either from a protected position in the crane's cab using the standard crane control stand or from the ground using the standard Liebherr remote control.
As early as the development phase, practical experience from overseas deployments by the German Army was included in the design to ensure that it met all the conditions to provide the requisite performance in full.
Consideration was also given to the development of a family of future armoured mobile crane vehicles for the German Army. Special attention in this respect was given to ensuring that as many components as possible were standard and readily available on the market. One strict criterion was that all the machines must be operated in exactly the same way. This means that there is no difference between the driver's seat and crane operator's stand on the G-BKF, an armoured crane or a standard crane supplied by Liebherr. This allows the amount of training required to be drastically reduced and incorrect operation to be ruled out to a large extent.
The special feature of this concept is the variable uses of the machine. There is not a need for rescue deployments every day but hoisting work is almost always required, whether it involves containers or unloading a truck. An extensive range of accessories ensures that rescue deployments are also possible. The important thing is that the team is familiar with the machine and works with it regularly so that they can carry out their duties quickly and confidently when required.
The G-BKF armoured rescue crane vehicle is flexible and versatile and can be used for a wide range of jobs whilst also being economical in terms of initial outlay and running costs.
