    2014/1/1 · This paper proposes a model-based technique for detecting wear in a multistage planetary gearbox used by lifting cranes. The proposed method establishes a vibration signal model which deals with cyclostationary and autoregressive models.

  • The article analyses and jointly evaluates structural solutions for the lifting mechanism in a bridge crane, in order to emphasize the technical aspects of system reliability in this context.

  • A crane operator has to perform various activities, such as loading and unloading of coils, setting and removal of convector plates, and routine maintenance work.

  • 1. Introduction Tower cranes are used extensively at construction sites to lift and move materials. They often rise hundreds of feet into the air, and can reach out just as far. As illustrated in Figure 1, a tower crane consists of several units: 1) the mast is the supporting tower of the crane; 2) slewing unit sits at the top of the mast, which allows the crane to rotate; 3) the operator

    With a maximum lifting capacity of 150 tonnes and a 66 metre telescopic boom, the LTM 1150-5.3 joins Liebherr’s crane range below the 180 tonne LTM 1160-5.2. The 10 per cent longer telescopic boom (compared to its predecessor) will hoist on average 15 per …

  • The smallest gearbox has a dynamic torque of 6,000 Nm and the largest can produce a dynamic torque of 944,000 Nm (with load spectrum L2, operating class T5, categorised according to FEA). The standard gearboxes designed for horizontal installation in rope winches can be adapted for drives powered by both electric and hydraulic motors and are thus, according to Liebherr, very flexible.
