Meeting the toughest capacity demands and environmental Crane type K4 electro-hydraulic four-rope grab cranes are self-contained units with all machinery enclosed In the crane housing. This protects them from weather, corrosion, dust and damage. The standard K4 range covers lifting capacities from 25 to 50 tonnes In grab operation, with outreaches of up to 36 m. To further Improve outreach, cycle time and positioning performance, the crane can be Installed on an eccentric platform. Each crane Is tested electrically, hydraullcally and mechanically before General design K4 cranes are designed to meet the rules of all recognised classification societies. The MacGregor control system ensures smooth, fast and stepless crane control. Hoisting, luffing and slewing motions are Independent of each other. This means that at their maximum capacity, K4 cranes can operate at full speed using all three movements at the same time. K4 crane design Is calculated according heavy-duty units, where U7-A8-Q3 applies to the whole crane, this equates - 1,800,000 hoisting cycles during the - up to 20 years lifetime, depending on the number of hours worked per year. HOISTING CAPACITY: Important crane criteria • High capacity, tonne/hours • High speed • Positioning performance • Operator convenience • Robust design • Closed hydraulic system; all motions are available at the same time at full • Planetary gears and hydraulic motors with fall-safe brakes Control system • Excellent and optimised control • Individual adjustment possibilities • Enhanced monitoring capabilities • Integrated diagnostic functions Available extras • Automatic greasing of slewing • SeaState selector
