The LMIS and LSI indicators show on the load chart screen for better visibility. As both the rod side and the barrel side are being measured, the two sensors complement each other and help provide accurate measurements in all temperature extremes. Internally, the pressure transducers have a redundant circuitry to ensure integrity of the measurement and to enhance diagnostic capabilities. Transducers are used to measure the pressure captured in the lift cylinder, which correlates to the amount of load and force on the telehandler boom. To calculate the load and position on the machine this system combines inputs like:įorces are calculated by measuring the lift cylinder pressure. To ensure the recognition system has chosen the correct attachment if multiple ones are in the vicinity, the system analyzes the signal strength from each attachment and selects the appropriate load chart.Ī load management information system provides the operator with an indication of how heavy the load is on the machine and where the load is in space. Once the system has detected the attachment, by using the unique number, it will match the attachment number with the corresponding load chart.

The sensor on the telehandler reads the attachment tag, providing the operator with the correct load chart.Īttachments are assigned a unique number and a Radio Frequency IDentification (RFID) tag, which sends radio waves to the RFID transceiver located on the telehandler through a long distance communication system. With automatic attachment recognition, the tag on the attachment and the sensor on the telehandler work together to provide the accuracy needed to deliver the operator with the correct corresponding load chart for the attachment that is fitted to the machine.

With automatic attachment recognition, that inaccuracy is gone. If the operator accidentally chooses the wrong load chart, the operator can get a false idea of the attachment and machine capabilities. Imagine spending time flipping through a load chart booklet, a booklet that has over 25 attachments listed in it. All three work together in the prevention of overloading and damage of telehandlers. These systems include automatic attachment recognition, a load management information system (LMIS), and a load stability indicator (LSI). Not only is damage to the telehandler likely, but in extreme cases, the machine’s stability can be affected.īy introducing three key systems, the risk of overloads can be greatly reduced. In addition, operators also risk accidentally misinterpreting the information provided on a load chart. There are cases where, despite following procedure, telehandlers have tipped due to overloading.

Telehandler or boom lift operators have been trained to know the weight and load center of each load they lift.
