This lets users adjust the belt without removing the load. According to Parker, this reduces maintenance and, together with the HPLA/HLE direct- mount gearbox, lowers ownership costs by 20%.
Both actuators handle speeds up 5 m/sec, loads to 1,600 kg, and generate up to 5,500 N of thrust force. Drive torque can be as high as 244 Nm. The HPLA can move loads 50 m, while the HLE actuator has a 20-m range. Repeatability is 0.05 mm.
