JCB is leading the way in clean technology that reduces harmful emissions and improves air quality in sensitive environments.
We see clean diesel as absolutely fundamental to the future of the construction equipment sector and its key role at the heart of developing infrastructure. However, there are certain applications where quieter, zero emissions plant can be advantageous.
First and foremost, with any machine is performance. With the introduction of this revolutionary new 1.9 tonne mini digger, JCB engineers have done what they do best. They have innovated to find a practical business solution. One that meets environmental and commercial needs in equal measure.
They have taken our premium specification diesel-powered 19C-1 conventional tailswing model and converted it without losing any specification. There is no compromise on performance with everything equivalent to its diesel counterpart.
The standard diesel engine is replaced with efficient JCB E-Tec technology. This includes a 48V electrical driveline, and three or four next generation 5kWh batteries, to deliver a full energy capacity of 15kWh or 20kWh. These battery packs use advanced lithium-ion cells.
The 19C-1E is equipped with the same retractable undercarriage and choice of digging equipment as the diesel model, providing a maximum digging depth of 2,576mm with the longer 1,100mm dipper arm. The machine shares the same structure, canopy, dig end, hydraulics and controls and it performs in exactly the same way. The only change is that the power pack changes from a diesel to electric and the fuel gauge is replaced with a charge level readout.
There is a substantial reduction in vibration and instant torque, improving the overall driving experience for the operator, but otherwise, operation of the machine is identical.
As the working conditions on sites become more and more restricted, safety becomes more and more important. With no tethers, unsafe trailing cables or extractors, the new 19C-1E gives operators the freedom to work anywhere, at any time, with quick charging and no compromise on performance.
This is the perfect machine for contractors who are working in emissions-sensitive inner-city environments or even inside buildings. And when rail contractors operate in tunnels and underground the new JCB electric mini means there is be no need to install costly exhaust extraction equipment.
Utilising leading-edge automotive battery technology, the 19C-1E delivers all of the performance of a conventional 1.9-tonne mini with a reduction of both internal and external noise levels.
In fact, at 7dBA lower than its traditional diesel stablemate, it is a massive five times quieter. This opens up further possibilities for contractors working after normal hours in urban streets without disturbing residents or for operating during normal working hours in noise sensitive environments, such as hospitals and schools.
The 7dB reduction to 86dB in external noise levels also allows for improved communication with co-workers / banksmen in any space.
The JCB 19C-1E can be powered by three or four lithium-ion batteries, to provide 15kWh or an optional 20kWh of energy storage. The 3-battery pack will last for 4 continuous hours, equivalent to a full day's work, dependent on the type of job. JCB’s monitoring of mini excavator usage across the globe suggests this far exceeds the daily usage of the majority of machines in this class – even including idle time.
The high efficiency of this advanced electric-hydraulic combination means a considerably lower cooling requirement
s which contributes to the longer battery life, as well as the much lower noise level. Not only this, there are 3 digging modes to choose from which maximises battery life and can extend the working day.
If the machine is left on, but not working, the battery will run down at a very low rate to conserve power and last 120 hours before recharging.
The machine is initially equipped with both 110V and or 230V charging, while a fast charge option will be available. The 230V 16A supply requires an eight-hour charge time from empty, while the 110V supply would require a 12-hour charge time. An on-board charger is provided as standard.
This excellent chargeablity is not detrimental to the life span of the batteries which have been designed to last the operating life of the machine – up to 3000 charge cycles
