CASE STUDY SPOTLIGHT:  HED® Display Reaches New Heights at JLG

HED was approached by JLG Industries, an industry leader in Aerial Work Platforms (AWP) for a CL-707 4.3” color display to use as the operator information center in their latest and tallest boom lift. The world's leading designer and manufacturer of access equipment required support for a display solution that would be easily readable in extremely bright sunlight conditions.  JLG also required a rugged solution that would provide additional protection for situations in the case of something like a wrench is dropped or paint is spilled onto the display.

The Application

JLG Industries has released the world’s largest self-propelled articulating boom lift, the 150JS, which can reach a platform height of 150 feet (45.72 meters). This boom lift has the longest outreach in the industry at 79 feet 3 inches (24.16 meters). Extendable axles provide stability without excessive counterweight to enable travel from the fully elevated position, along with four wheel steer/crab steer and provides a tight turning radius for more precise positioning. JLG wanted to provide the operator with critical stability data for the lift via an easily readable, robust display.

Project Challenge
  • Protection from extremely bright sunlight for a readable display 
  • Protection from potential objects dropping on to it, and a robust sealer to protect against exposure to the elements
  • A low-cost, replaceable protective covering over the display
  • High-resolution LCD to display precision graphics
The Solution

After discussing the requirements in detail, HED recommended the CL-707, 4.3” color display as the ideal product for this application.  The CL-707’s high-resolution (480x272 pixels) allows detailed graphics to be displayed. In addition, the display utilizes an extremely bright backlight (500 cd/m2 or nits) making the display easy to read in the brightest conditions. To meet the challenge of objects potentially dropping on it, HED designed a clear polycarbonate thermoplastic protective guard to go over the LCD. The hinged guard can be lifted for cleaning or be quickly replaced if damaged. As an added benefit, this CAN-based display can be easily reprogrammed over CAN or USB.

Success

JLG is now able to provide the operatiors of their latest and largest boom lift with the durability of the CL-707 Display. The operators are now able to read critical stability data, even in the brightest conditions. If by chance the LCD guard gets damaged, it can easily be replaced without the need to replace the entire display.
