Page 56 Maintenance overview 5.3 Periodic inspections 5.3.1 Load hook inspection The hook opening on the load hooks must be checked regularly for defor- mation. The hook opening must not have increased by more than 10% of the original dimension y, y1, y2. The original dimensions y, y1, y2 are specified in field (2) on the load hooks.
Page 57 Maintenance overview 5.4 Measures required for winch monitoring Measures required for winch monitoring Also observe the information on the general inspection of the hoists; à p. 8 - 13. These measures for monitoring the winches (hoists) were compiled by the German Machine Builders' Association (VDMA) and are to be used for all truck cranes according to the German Accident Prevention Regulations for Winches, Hoists and Tractor Machines, BGV D 6 (VBG 9 ) and BGV D 8 (VBG 8) .
Page 58 Maintenance overview 5.4 Measures required for winch monitoring The actual service life of a winch is affected by a number of additional exter- nal factors, such as: 1. Overloading caused by improper use of the truck crane. 2. Insufficient maintenance: Oil is not changed at the specified intervals.
Page 59 Maintenance overview 5.4 Measures required for winch monitoring Determining The truck crane's load spectrum is divided into groups (see also ISO 4301/1, the operating FEM 1.001): conditions (load spectrum) When determining the load spectrum, the existing rope pull is used as the standard, i.e.
Page 60 Maintenance overview 5.4 Measures required for winch monitoring One of the load spectrums listed above should be selected on the basis of the actual operating conditions and entered in the crane logbook for the respective testing interval. Note for truck cranes: The load spectrum L1 and the load spectrum factor Km = 0.125 are generally applied to truck cranes in assembly mode.
Page 61 Maintenance overview 5.4 Measures required for winch monitoring The general overhaul is to be arranged by the operator and performed by the manufacturer or a representative authorised by the manufacturer. The results are to be entered in the crane logbook. The manufacturer or an authorised representative will specify a new theo- retical service life D upon completion of the general overhaul.
Page 62 5.4 Measures required for winch monitoring 5.4.3 Example A GMK5250L is equipped with a separate operating hours counter for the hoist and is classified by Manitowoc Crane Group Germany GmbH as fol- lows: Power unit group: Load spectrum: Light L 1, Km = 0.125...
