ALWAYS THE RIGHT AMOUNT
FLEXIBLE COUNTERWEIGHT
No matter what loads need to be lifted or moved and how strong the main booms are, there is no way around a balanced concept for central ballast and counterweight stack. This is especially true if the setup is reliable and a misconfiguration is immediately detected.
CENTRAL BALLAST
The crane operator can assemble the two 16,540 lb central ballasts for the carrier from the cab using the crane or, optionally, entirely by remote. As per the poka-yoke principle – which avoids the incorrect installation of individual parts through their geometric properties and dimensions – the two central ballasts are mechanically designed to prevent mix-ups during setup. A sensor confirms the installation.
COUNTERWEIGHT STACK
The two options also apply to setting up the counterweight stacks on the central ballast: the crane operator takes this into his own hands with the crane, or controls the process via remote control. In any case, there is no additional work at height - because the operator or the riggers do not have to secure the counterweights on the superstructure. The counterweights are mechanically locked on the crane superstructure using automatic hydraulic cylinders. This connection enables the reliable, robust operation of the GTC-2000, even in rough terrain. The counterweight of 99,225 lbs is stacked with the help of slings – in one lift or in a total of 5 lifts. The amount of counterweight is automatically measured to ensure this process also runs without errors.
