IMAGES PREVIEW

Together, these sections equip maintenance personnel with precise diagnostic criteria, exact replacement tolerances, and step-by-step disassembly/assembly instructions. Whether testing nitrogen precharge in brake accumulators, resetting PLC maintenance intervals via the Visumatic service screen 7860, or measuring disc wear on the travel gear wet multi-disc brakes, this manual provides direct OEM procedures to maintain full operational integrity.

In-Depth Mechanical, Hydraulic, and Powertrain Systems

The Gottwald Mobile Harbour Crane G HMK 6407 Maintenance Manual leaves no operational system uncovered. Technicians are provided with complete maintenance procedures for the Cummins QST 30 G2 engine (895 kW at 1,800 rpm), including full-flow/bypass oil changes, water separator servicing, fuel transfer pump operation, and coolant inhibitor ratios. The hydraulic section details circuit maintenance for the three variable-displacement axial piston pumps, the massive 2,600-liter fluid reservoir, and specialized high-pressure line filters (3µ to 10µ ratings) equipped with differential pressure clogging transmitters.

For the undercarriage and travel gear, the document covers torque requirements for the 28-wheel assemblies (700 Nm), monthly differential and planetary hub gearbox level checks, oil flushing intervals, and brake piston clearance limits. Upper superstructure documentation covers detailed adjustments for the hoist caliper brakes (maximum 1.0 mm air gap), sintered metal lining replacement thresholds, hydraulic bolt pretensioning requirements (630 kN for slew gear fasteners and 900 kN for the 58 tower mounting bolts), and DIN 15020 wire rope discard thresholds.

Master Maintenance Checklists & Electrical Architecture

Structured according to crane master switch operating hours (Std HS), the manual enables teams to maintain rigid compliance with factory service intervals from 1,000 up to 20,000 hours. The electrical maintenance sections guide technicians through high-voltage chassis electrics cabinets, slip ring assemblies, PLC bus transmission checks, and anti-condensation heating circuits across all major motors. Utilizing the on-board Visumatic screen navigation (access screens 1000, 7000, 7800, and 7860), your maintenance crew can rapidly verify operating hours, evaluate warning indicators, and clear scheduled maintenance data directly from the tower cab.
