Standard drum bearings (such as cast or welded) must reliably transmit radial and axial loads generated by rope winding, unwinding, braking and changes in direction of movement.
The choice of bearing type, size and mounting method is based on drum diameter and length, load capacity, operating mode and required service life. We tailor the solution to the specific operating conditions to ensure a stable, safe stroke with reasonable maintenance requirements.
Split drum bearings are used wherever reliable placement of the cable drum is required, as well as easy access for assembly and maintenance.
The bearing housing is designed as a split bearing housing so that the top cover of the bearing housing can be removed and the bearings inspected without having to disassemble the entire housing. This significantly reduces downtime when servicing the lifting equipment and also, for example, when replacing the entire cable drum.
The weighing drum bearings combine the function of the rope drum bearing with the measurement of the load on the lifting device. The bearing unit is supplemented by an integrated force sensor that evaluates the reaction from the drum and thus allows the actual weight of the suspended load to be determined indirectly.
The system provides continuous load information and can be used to display weight to the operator, for overload protection and for recording operational data.
