  • What is a mechanical load brake, and why does it matter …

    Others call for an annual load test to check the functionality of the load brake – in some cases specifying a test at 25 percent of the rated capacity and others recommending at least an 80 percent load. I have also conducted near-rated-capacity load tests in which the load is lifted just a few inches off the floor.

  • To find the correct load limiter you need to: 1: find the lifting capacity (e.g. 20 T) 2: find the number of layers on drum (e.g. 4) 3: divide the lifting capacity with the number of lays (20 T divide by 4 = 5 T) 4: find the wire diameter (e.g. 10 mm) Mechanical load limiters
