How to choose products

Load Moment Indicator – LMI

For hydraulic cranes, the LMI reads its load value using a pair of pressure transducers, which read the cylinder pressures of the lift cylinders

Rated Capacity Indicator – RCI

On a Rated Capacity Indicator, the load weight value is calculated by reading the strain on the wire rope. This is done by using a load pin in a sheave, a running line tensiometer (linerider) or a dead-end load cell installed at the becket end. A digital load chart is also available to show load capacity.

Load Indicator – LI

This is the simplest form of load monitoring. Here, a strain gauge device is used to read the wire rope tension producing a load value. The load sensing device can be installed in line to the crane rigging or can be placed under hook.

What is crane load?

Each crane has a load chart that, in short, specifies the crane’s capabilities — detailing its features and how its lift capacity varies when considering distance and angle. … Before a crane is rented, transported, employed or purchased, the crane chart must be consulted.

What is a load moment indicator?

Load Moment (or Rated Capacity) Indicator means a system which aids the equipment operator by sensing (directly or indirectly) the overturning moment on the equipment, i.e., load multiplied by radius.

How does a load moment indicator work?

Using different sensing devices, the Load Moment Indicator monitors various crane functions and provides the operator with a continuous reading of the crane’s capacity. The readings continuously change as the crane moves through the motions needed to make the lift.
