Access equipment maker JLG has introduces its all-electric DaVinci AE1932 scissor lift, a 5.79m model with zero hydraulics and zero emissions to eliminate leaks and pollution on job-sites,
Purpose-built for applications where stringent environmental regulations must be met, JLG says every component on the new DaVinci scissor, including the control, lift, drive and steering systems, is fully optimised to reduce the machine’s energy consumption by up to 70% as compared to a traditional scissor lift. This reduced energy consumption allows for the use of a single, lithium-ion battery.
The all-electric DaVinci AE1932 scissor lift has a 275kg indoor/outdoor capacity rating and a 4mph travel speed to move quickly around job-sites. The machine has a compact footprint, weighs 1,564.89kg and has 25% gradeability.
Shashank Bhatia, senior director of engineering for mobile elevating work platforms (MEWPs) at JLG, said: “The DaVinci AE1932 scissor lift represents the next generation of electrification. While there is no shortage of battery-powered or electric scissor lifts on the market today, these other models continue to include hydraulic cylinders for actuation, which require hydraulic oil for operation, leaving the possibility open for messy leaks on sensitive job sites. JLG continues to push the envelope in innovation around the entire construction ecosystem, from our rental partners to job-sites. This new JLG all-electric machine unlocks new possibilities and applications where these types of machines could not be used in the past due to concerns surrounding leaks.”
According to JLG, its DaVinci lifts use a distributed architecture where each system (lift, drive and steer) is connected independently, helping reduce voltage drops and latency, while enabling the control system on the scissor to connect and communicate directly with each system.
“Because the control system is fully connected to the entire machine, the DaVinci scissor can transmit data back to operators, fleet managers and service technicians via Bluetooth and cellular networks. This sets the stage for new features like the DaVinciGo app. This app provides real-time machine health and battery status information and the ability for service technicians to perform remote diagnostics and push over-the-air software updates,” said a statement from JLG.
The drive system on the all-electric DaVinci lift has permanent magnets which generate torque and create motion to spin the motor. It is estimated that permanent magnet performance can increase the efficiency of a motor by up to 20-30% on average. Motors with permanent magnets have a long life and require zero serviceability, the manufacturer added.
For smooth operation, the independent controllers of the DaVinci lift’s steering system are designed to help reduce tire scrubbing on job-sites, which helps control tire wear and limits damage to sensitive flooring, JLG said.
The AE1932’s intuitive steering system allows DaVinci lift operators to easily manoeuvre the machine into and around narrow-access and space-restricted areas to get work done where it’s needed. Meanwhile, the lift system on the new scissor lift is designed with an electromechanical lift actuator, replacing the hydraulic cylinder design of traditional electric scissor lifts. Since there are no hydraulics, the AE1932 does not leak, which means it can be used without diapers.
“The simplified design makes the AE1932 noticeably different when working at height. Traditional battery-powered lifts have hoses routed throughout the scissor stack, whereas the DaVinci lift has no hoses for a clean, modern appearance with significantly reduced maintenance and service requirements. Furthermore, the DaVinci scissor lift system is engineered to recover energy as the platform descends, sending it back to the battery to help maximise use between charges,” Bhatia added.
According to JLG, the unit can be fully charged in as little as 3-1/2 hours, increasing its utilisation throughout the workday as compared to traditional electric powered lifts that require up to three times longer to charge. For additional productivity gains, the system can also be opportunity charged in five minutes or less for 30.48m of drive, plus enough torque for loading. The DaVinci lift’s lithium-ion battery can last up to 10 years, which obviates the need for replacement, and requires no maintenance, throughout the entire design-life of the scissor lift.
