Another model is McGregor cranes, which are very strong and durable, suitable for marine environments, and have versatile capabilities and long life. The cranes are backed by unrivaled global service support and a proven track record of delivering more than 13,000 cranes worldwide over the past 50 years. One of the standards in these models is a GP crane controlled from a platform above the rotating ring. A portable electric remote control unit is available as an option. GP electro-hydraulic cranes are stand-alone units. The standard range covers capacities of three to 25 tons and covers up to 24 meters. The products in this category are hydraulic cranes for service operations, relocation of stores and special applications that meet any need under any circumstances. All crane movements are smooth and fast with no step control. Two crane movements can be used simultaneously at full capacity but at low speed. All types of cranes use the same basic machines, but the components are different in order. GP cranes are designed for temperature ranges from + 45 ° C to the lowest ambient operating temperature for global trade based on the requirements of classification societies.
