MK 88-4.1

Product catalog summary
Technical Specifications
The crane is equipped with a spring-loaded hand brake for the 2nd, 3rd, and 4th axles, an exhaust retarder, and a Liebherr braking system. It features a ZF-Servocom hydraulic steering system with active rear axle steering and five electronic drive programs. All axles are steered, with the 2nd, 3rd, and 4th axles driven and having differential locks. The suspension is hydropneumatic with automatic leveling and hydraulic locking.

Driver's Cab and Legal Considerations
The driver's cab is spacious, made from corrosion-resistant steel, and includes sound and heat-absorbing materials. It features safety glazing, a reversing camera, and complies with EC directives. Legal notes stress compliance with national regulations for maximum axle loads.

Additional Equipment
The crane can be enhanced with a Plus package for increased load capacity, a divisible basic ballast for reduced axle loads, and an emergency stop system. It supports a 32-ampere external power connection and includes a storage area, combination box, trolley camera, and LED rear area lighting.

Crane Operation
The slewing platform is constructed from steel plates and connects to the crane carrier via a Liebherr slewing ring. The jib is a three-section assembly with hydraulic slewing and standard positions of 0°, 15°, 30°, and 45°. The crane has a 4-point hydraulic outrigger system with automatic leveling and an electronic inclination display.

Power Supply and Electrical System
The crane is powered by a 48.0 kVA diesel generator, with an alternative external power supply option. The electrical system includes a 24 V DC setup with batteries, rotating beacons, and a programmable logic controller (PLC).

Transport and Engine
Designed by Liebherr, the vehicle features a torsion-resistant structure and is powered by a 6-cylinder diesel engine with a ZF 12-speed gearbox. It can travel up to 80 km/h forward and 7.7 km/h in reverse, with a gradient capability of less than 60%.
