To provide a direct sense of the crane during operation, the crane cab is mounted directly to the tower. On cranes with a crane cab above 30 m, an operator lift comes standard, so the cab may be reached in a safe and fast manner. If required, the crane may also be operated by radio remote control. Displays in the crane cab show the crane driver things as load and radius instantaneously, so he has optimal control and command of the machine. A big advantage of the Spierings cranes is the fact, that the counterweight always remains on the crane, even during transport. This will save a lot of time and transport costs! Thanks to the crane's compact design, it does not need much space for rigging. On the most recent models, the jib unfolds high in the air, so trees, bushes or buildings do not present problems anymore. The crane is driven by a separate diesel engine on the superstructure. This way the truck engine is spared and also the fuel consumption is sharply reduced. The operating environment quiets down and the truck engine's life increases. The superstructure is fitted with a control module (Programmable Logic Controller) in the control box. This PLC checks and controls all crane movements.
