740 kNm knuckle boom crane


MKG hydraulic marine crane, model HMC801HP, knuckle boom type with special crane base for stationary mounting, cranked column in all-steel design, slewing ring gear with slewing gear assembly and hydraulic slewing connections for continuous rotation (two slewing motors - slewing torque 75.000Nm), jib up to 8-times hydraulically extendable under load to max. reach of 20,35m. All rams are double acting and the piston rods are hard chromium plated, complete hydraulic system consisting of:


Danfoss control valve bank consisting of individual valve sections for all crane functions, high precision with integrated suction and safety valves. Radio remote control (HBC), consisting of transmitter with linear or cross-lever controls, receiver, charger (12/24V) with two re-chargeable batteries, automatic frequency search, emergency-off, extra cable for cable remote control, variable speed choice. Load holding valves at lifting-, jib-, and extension rams. Overload protection valves with visual warning device, emergency shut-off buttons at all controls according to CE-standard. Black box with digital display in a stainless steel housing. Safety hook with latch. Pressure accumulator for lifting cylinder to minimize centrifugal forces acting on the load-bearing components of static mounted cranes. Steel cabin for operator (heating system optionally).


Hydraulic winch 6.000kg pull max. at single line/1st layer resp. 5.000kg/3rd layer, incl. control valve, average speed 26m/min. at 80l/min. oil flow, rope dia. 16mm, cable length 55m (spin resistant), incl. control valve, pulley and safety hook.


KTL-treatment of steel structure, i.e. electrostatic coating process (cataphoretic painting in accordance with corrosion protection class C5, DIN EN ISO 12944-2) against corrosive environment, crane base - St 52-3, column/booms - St e 460, cylinder tube - St 52-3, piston rods – twice chromium plated (option: stainless steel), bushings - seawater proof bronze, (optional: hose-ends/clamps/ piping in stainless steel), sandblasting, 300µ-coat colour system, painting RAL 9005 - black.


This crane is manufactured according to German Standard DIN 15018 resp. EN 12999 to meet marine specifications for provision/service crane type "A" at 5°heel/2° trim with full load.
