This weightlifter can handle up to 400 metric tons and requires no heavy tools for assembly and take-down. “Ther.” The remote-controlled operation increases overall visibility, therefore increasing safety. (To see how it works, check out the video at the bottom of this story.)
Railings and platforms remain on the upper carriage during transport and can be folded out at the jobsite. The winch can be installed in the same easy manner – simply position it with the assembly cylinder and pin it from a secure distance with the remote control.
Despite its size, the 46-ton LR 1400 SX has a wide range of applications, including building bridges.
The LR 1400 SX shows off its flexibility and mobility when space gets limited. The new model can adjust its tracks to navigate tight spaces and the four crawler drives make for smooth operation.
The gradient travel aid allows for safe travel on slopes. It displays the center of gravity of the machine and warns the operator before entering an unsafe zone.
The Ground Pressure Visualization system calculates the current ground pressure of the crane in real time and compares it with the specified safety limits. The ground pressure is displayed in the cab, making the operator aware of any critical conditions. “This is a super feature. We have to constantly observe and monitor the ground conditions,” says Belcher.
Additional plates at the front and rear reduce the ground pressure by up to 52 percent. “Specifically, the wide crawlers and the ground pressure reduction plates convinced us,” says Ludger Holtmann, technical director, Depenbrock.
