Overload protection
appreciably prolongs the service life of a rane's hoisting gear and
rope drive mechanisms. Overload protection devices are
therefore necessary for cranes and elevators. In adition to the known VAHLE overload protection system, a new generation of devices has been developed with integrated collective load data memory that meets the requirements specified in FEM 9.755 and VBG 8. Cat. 9b |
System overview |
VAHLE overload protection devices with integrated collective load data memory write the individual loads, divided into load groups, together with the associated load application times and load cycles into the memory. The memory may be accessed and evaluated at any time via a PC with RS 232 interface. The crane expert uses these data to caluculate the residual lifetime of the hoisting gear. Components
