JLG Industries has updated its LRT series of rough terrain scissors. These model year upgrades are the result of customer feedback aimed at improving the operability, serviceability and efficiency of these industry-leading machines.
"Our customers are looking for high-capacity rough terrain scissor lifts capable of carrying more employees, equipment and tools on the platform around the work site," said Rafael Nuñez, senior product manager, scissor and vertical lifts, JLG Industries. "The latest upgrades to our LRT series offer faster serviceability and added durability to help customers get the job done faster, safer and at a lower cost."
The upgraded series offers refined platform control joystick operation for smoother and more precise machine repositioning. In addition, control system upgrades provide the system with feedback to improve drive control proportionality. Left and right steer functions now receive renewed digital inputs to ensure a higher level of functionality and improved response for the operator.
Leveling jack performance has been improved to deliver more accuracy and quicker leveling speeds. The leveling jack interface is enhanced by integrating a dedicated leveling function within the current lift/drive switch.
The updated 530LRT model will utilize proportional lift valves for the upper and lower lift cylinders, providing a smooth, controlled proportional ascent and descent. The upgrades also include smoother lift-up and lift-down operation.
In addition to their ability to support larger loads, the LRT series scissor lifts offer excellent gradeability and maneuverability while traversing rough terrain. These types of scissors typically offer 2-3 times the capacity and 3-5 times the platform space of boom lifts.
LRT series scissor lifts have been designed with service and uptime in mind. Steel hoods protect components while providing full access for inspections and service. The complete lineup is powered by Tier 4 Final diesel engines, which do not require the serviceable emissions technology found in larger engine systems.
All machine calibrations can now be performed from the stowed position with a single click of the analyzer, and the refined elevation sensor calibration no longer requires recalibration after a software update. All software updates will also improve the customer experience with the upcoming A92.20 compliance. Additionally, all LRT models are now calibrated with the same procedure, which has been simplified to improve serviceability. This new functionality will help customers optimize machine uptime.
Additional features include a 60-degree swing-out engine tray for enhanced access and fold-down ladder and swing-out tray for easier access to engine and hydraulics. The multifunction digital indicator (MDI) display communicates full language versus fault codes for improved serviceability and faster troubleshooting to reduce the number and duration of service calls. And operation and control layouts are the same in the entire line for ease of training and operation.
The 530LRT now has the same hood and ladder design as the 330LRT and the 430LRT, and the entire series is equipped with new mufflers, lowering the sound level by 5 percent. Engine noise and vibration levels are reduced by engine isolators and improved door bumper locations. The angle tilt sensor is relocated and rerouted, so it's less prone to damage as the scissor arms move.
