FOLDABLE KNUCKLE BOOM CRANE-Load Moment Indicator

FOLDING BOOM CRANE/FOLDABLE KNUCKLE BOOM CRANES

Due to their structural characteristics, folding-arm truck-mounted cranes(Foldable knuckle boom cranes) require LOAD MOMENT INDICATOR equipped with superior sensors and more complex, precise programming algorithms compared to other crane types. This ensures the LOAD MOMENT INDICATOR maintains high accuracy. Leveraging our extensive experience and superior programming algorithms, we provide stable-performing LOAD MOMENT INDICATOR for folding boom truck-mounted cranes. Should you require further information about this product, please feel free to contact us for detailed specifications.

█PRODUCT DESCRIPTION

The WANPU Load Moment Indicator consists of a central microprocessor unit,display, pressure transducers,length/angle sensor, and anti-two block switches.The fixed data regarding the crane, such as capacity charts, boom weights, centers of gravity and dimensions are stored in memory chips in the central processor unit. This data is the reference information used to calculate the operating conditions.  Boom length and boom angle are registered by the length/angle sensor, mounted inside the cable reel which is mounted on the boom.

The boom length is measured by the cable reel cable which also serves as an electrical conductor for the anti two-block switches.The crane load is measured by pressure transducers attached to the piston and rod side of the hoist cylinders.The real value, resulting from the pressure measurement is compared with the reference data, stored in the central processor memory and evaluated in the microprocessor. When limits are reached, an overload warning signal is generated at the operator’s console.

█PRODUCT FEATURES

Load charts can be programmed into the display.

Use automatic compensation method for the force sensor.

The display has a built-in processor, reducing the number of components to be installed in the crane cab.

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.
