Description

NMF DK II Board Crane Instruction Manual – Order 80107

This PDF is the complete NMF DK II board crane instruction manual issued for the two shipboard cranes built under Order 80107 at Zhoushan Shipyard on Hull No. 2027 during 2006. It documents Crane 1, type DK II 45027.5/35032.2, and Crane 2, type DK II 45027.5/35031.5 – twin electro-hydraulically driven loading cranes rated at 45 t, 35 t and 16 t load steps with maximum outreach of 32.2 m and 31.5 m. The document is the 2006 Edition instruction manual published by Neuenfelder Maschinenfabrik GmbH (NMF) of Hamburg, and it runs 324 pages across operation, hydraulic function, electrical controls, troubleshooting, maintenance, emergency procedures, spare parts and drawings.

For the marine engineer or shore technician working on these cranes, the DK II instruction manual is unusually self-contained: it pairs the top-level operation and safety rules with the underlying hydraulic schematics, the electrical troubleshooting trees, and the maintenance intervals and lubricant specifications that keep the crane survey-ready. The inclusion of the Zollern winch unit and Brueninghaus Hydromatik pump spare parts lists alongside the NMF part lists means the reader can trace a failed component down to the correct part number without leaving the document.

What This Manual Lets You Do

Working from this NMF DK II board crane manual, an operator can confidently run the crane through its three load steps – 45 t, 35 t and 16 t – and use the half-load key switch correctly to reach the doubled 0-32 m/min hoisting speed. A maintenance technician can follow the maintenance schedule for the winch gears, turning gears and pump distribution gear, service the gear oil cooler filter and hydraulic oil filter, grease the wire rope and roller revolving joint, and adjust the slack rope switch and gear cam limit switch exactly as NMF specifies.

For electrical fault-finding, the fault search diagrams in the DK II 45027.5/35032.2 and 45027.5/35031.5 instruction manual walk through the most common failures – motor will not start, lifting winch not turning, luffing gear not turning, crane not slewing – linking each symptom to its probable cause and the correct remedy. The brake relay monitoring section shows where to read the fault lamps on the interference pilot print card, and the RESET button procedure explains how to bring the crane back after a hose rupture or a gear oil cooler trip.

The emergency section is equally practical: it gives the hand pump connection steps for hoisting the hoisting gear, luffing gear and slewing gear brakes when the main power has failed, including the maximum brake opening pressure and the throttle and bypass valve settings that must be restored afterwards.

Why It Matters

Shipboard cranes are surveyed and load-tested, and the correct NMF procedures and specifications for limit switch adjustment, load pressure switch setting, brake inspection and rope discard criteria are what keep the crane inside its class requirements. The technical data in this manual – 45 t capacity at 27.5 m outreach with +/- 5 degrees heeling and +/- 2 degrees trim, 160 kW main pump motor, 440 V / 60 Hz supply, 0-0.8 rpm turning speed, 70 s luffing time – is the reference against which any deviation should be judged.
