WIKA Mobile Control has introduced the qSCALE I2 TH rated capacity indicator (RCI). The qSCALE I2 TH RCI system was designed specifically for telehandlers and is suitable for both OEM and aftermarket telehandler applications.
The qSCALE I2 TH features a user-friendly 4.3” color graphic display that provides the operator with actual and allowable load, boom length, boom angle, load radius & height. The system also includes a cable reel for measuring the length and angle of the boom and pressure sensors that measure the hydraulic pressure in the cylinders.
Depending on specific requirements, three other optional system components are available. If a longitudinal load moment indicator or limiter is required, the rear axle sensor can be added to measure the strain on the rear axle. The gSENS WGX sensor can be added to indicate the tilt of the chassis. The system can be upgraded to a rated capacity limiter (RCL) by adding the cSCALE DIO module to lockout the machine in the event of an overload.
One of the benefits of the RCI system is that it reduces operator error. While operating within the allowable range (determined by the load chart), the top bar graph on the display will be green. As the operator starts to reach the allowable limits, the bar graph will change from green to yellow. Once the limit is reached, an alarm will sound and the bar graph will turn red. If the cSCALE DIO module is installed, it will cut off the operator’s ability to telescope out and boom down if the limit has been reached.
The system also enables the machine owner to maximize the machine’s lifting capacity. This ensures that the machine isn’t overworked and the operator isn’t lifting loads that they shouldn’t be.
The integrated data logger tracks machine usage and helps to determine whether a machine has been misused. Using a USB stick, the data logger information can be extracted from the console to an Excel spreadsheet. The data logger provides a report that indicates machine productivity and any overload instances.
Calibration can be done through the console without the need for additional software tools. To validate the calibration, several measurements have to be taken with known loads.
With the addition of the rear axle sensor, the system reduces the risk of accidents from tipping and increases the operator’s stability awareness of the machine. When the operator is lifting a load and extending the boom, this extends the radius. As the boom is further extended, the right bar graph on the display will change from green to yellow as it gets closer to reaching the stability limit.
