The bearings of the linear guide for the adjustment mechanism of container spreaders in the Australian harbour of PORT BOTANY RMG were originally equipped with bronze bearing bushes. However, as early as during the trial run considerable wear of the bearings was noticed, together with an inacceptable slip-stick. Retrofitting the equipment with maintenance-free, highly wear-resistant MANGACHOC slide bearings solved this problem. (Ref.33)

A company in the port of Rotterdam operates several ore handling bridges. The jibs used to be equipped with lubricated steel/steel spherical plain bearings or with maintenance-free PTFE spherical plain bearings. These bearings, however, failed prematurely either on account of adhesion due to insufficient lubrication or because the PTFE inlet was rotten. As a consequence, maintenance-free, highly wear-resistant spherical plain bearings were mounted to solve the problem. These have been in operation for years without showing any wear. (Ref.9)

The hinge point of the jib and the tie bar swivel joints of the container gantry cranes in the Rotterdam port of MAERSK CTT used to be equipped with conventional slide bearings. With increasing fretting over the years, a landside/seaside rail offset occurred. The thus reduced crane trolley operation led to a decrease in handling capacity. Initially, one gantry crane was retrofitted with highly wear-resistant MANGACHOC slide bearings in the couse of an experiment. The achieved reduction in wear led to a substantial increase in the handling capacity and to the decision to retrofit all 9 gantry cranes in the same manner. (Ref.65)

In the past, efforts were made to extend the service life of less than two years by trying various material combinations in order to avoid extended downtimes and high repair costs. By using MANGACHOC soles, the wear at the rail connections could be considerably reduced and the service life extended by 2-3 times. (Ref.77)
