Komatsu has redesigned its Joy 02ESV soft-rock scoops with 240 V of battery power and OptiDrive technology to improve operator comfort and offer a longer operating time between charges.

Coming in three different models – 02ESV36, 02ESV56 and 02ESV60 – the scoops offer bucket capacities of 3-5 cu.m and maximum payloads of 18.2-28.7 t. The smallest scoop, the 02ESV36, is suited to seam heights of 91-160 cm, while the largest scoop, the 02ESV60, has a recommended seam height of 142-211 cm.

The OptiDrive technology can improve reliability, boost operator productivity, improve motor performance and help reduce maintenance costs, according to Komatsu. It is also easier to maintain and troubleshoot because it has fewer cable runs.

Designed to help minimise downtime, these scoops have new electronics that eliminate switches, and the colour display provides real-time operational and fault information to keep operators informed. Additional drive input modules allow the OptiDrive control system to interface with third-party proximity detection systems.

With less heat and noise compared with diesel power, the 240 V battery power contributes to improved working conditions. These Joy scoops also have improved motor efficiency for increased motor life and enhanced tramming, while improved ergonomics help keep operators more comfortable, Komatsu said.

To provide increased power and reduced downtime in the most demanding applications, the scoops are equipped with Dana drive axles configured specifically for the application. For durability and longevity, the centre section has been redesigned and includes heavy-duty pivot bearings and pins. The frame is rigorously engineered for reliability and transporting heavy payloads, according to the company.
