With market-leading positioning performance, efficiencies and capacities, the MacGregor K4 grab crane delivers a full range of benefits to dry bulk operators.
This is backed-up by our lengthy experience, unrivalled global service support and proven track record of more than 13,000 crane deliveries worldwide over the past 50 years.
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 36m.
To further improve outreach, cycle time and positioning performance, the crane can be installed on an eccentric platform.
Each crane is tested electrically, hydraulically and mechanically before delivery.
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 to the latest FEM rules,1.001.
