Demag extends industrial hoist range
By Alex Dahm06 March 2009
The FDR foot-mounted hoist is a further development of the DR electric rope hoist, in line with market requirements, says the company.
"The FDR achieves high lifting speeds and, therefore, high handling rates. For precise positioning, the foot-mounted hoist unit features two hoist speeds as standard. With its ProHub function, the FDR also features load-dependent speed control," says the company.
The company has improved its Demag KBK crane construction kit with two new developments. The Bo-Clip provides considerable improvements in handling and significantly faster assembly, says the company, as no tool is needed to fit the new pin retaining device. The second development, the X crane suspension is used to connect the crane girder to the trolley in the crane runway. "This newly developed component not only simplifies assembly, it also makes the installation easier to maintain and improves the safety of KBK suspension crane installations," Demag explains.
Another company development, this time in its process cranes segment is a scanner for automatic overhead cranes in the recycling, bulk material industry and waste burning plants.
"The scanners, fitted below the crane bridge, permanently track the height contours of the heaped refuse as the crane travels over it. The software uses the information to determine a constantly updated height profile of the refuse bunker. The grab no longer has to be raised to the highest possible position for the crane to travel over it. The grab position is adapted according to the profile - even while the crane is travelling. This saves time, increases the handling rate and, therefore, improves efficiency.Demag says future developments in process cranes will come as customer demand longer lifecycles. "So the focus will be made on investment and also on the following costs of service and refurbishment," says the company.
