Benefits of a Battery Powered Excavator

While harder-working machines like excavators have almost exclusively been diesel-powered, more and more contractors are looking for better electric solutions. Hybrid machines bring limitations due to a trailing cable but can offer zero emissions and lower noise. Battery-powered machines, however, require no cable and bring with it all the advantages of plug-in electric equipment.

Cratos’s battery-powered excavators are taking advantage of rapid improvements in lithium-ion battery technology. Not only are they providing better solutions, they oftentimes outperform their diesel counterparts. The following are a few reasons why your company will benefit from making the switch to a battery-powered excavator:


Less Noise

The noise level is a common complaint made by residential neighbors. With quieter, electric machines, construction can minimize noise complaints, and often allows for construction to be performed at stricter areas and with longer workdays. Some jurisdictions even allow for construction sites to be run at night.

With a traditional excavator, it is nearly impossible to speak to others on the jobsite, but with a battery-powered machine, critical commands can be heard. The ability to communicate easily prevents dangerous construction hazards.

A compact machine, by its very nature, puts the operator closer to the engine. However, Cratos’s battery-powered excavators incorporate quieter gears using materials with intrinsic sound-deadening characteristics and stiffening the structure of the engine block itself to achieve significant noise reduction.


Zero Emissions

Battery-powered mini excavators meet zero-emission and low noise requirements for operating in urban workplaces that are close to residential areas.

Spending the whole day in the trench means inhaling a lot of fumes. With a battery-powered excavator, there is no exhaust gas to inhale. Running electric motors contributes to less pollution in comparison to internal combustion engines, since they do not rely directly on burning fuels. Not only does this produce a safer working environment, but also utilizes cleaner construction equipment.

Stricter regulation on the global, regional, and local levels are emerging for heavy machinery and equipment. Some jurisdictions are placing bans on diesel and stricter regulations on nitrogen oxides and particulates. The emissions standards that are set by these regulations are more easily met with electric equipment. While it isn’t the primary reason to purchase a zero-emissions equipment, doing so often results in tax incentives for construction companies who invest in this machinery.


Clean Energy Enhancing Technologies for Small Engines

A small engine can still feel and perform like a larger one with efficiency-enhancing technology like ‘smart’ turbocharging that improves the machine’s responsiveness and drivability. This combination of features makes a compact machine as comfortable to operate as its full-size counterpart. A smaller displacement engine with turbocharging and rail fuel systems ultimately has more power due to more air in the cylinder.

Cratos’s CMX battery-powered mini-excavator has been designed with an engine that can withstand higher mechanical and thermal loads without sacrificing durability or reliability. More efficient compact machines depend on smaller displacement engines with higher power densities.


Go Electric with Cratos Equipment

The Cratos CMX18 battery-powered mini-excavator offers cost-effective, eco-friendly and efficient power to tackle projects quietly without the burden of fuel costs. It is powered by a hydrostatic transmission with orbital motors and planetary drives with negative control brakes and priority valve. Its double-speed driving motor powers a track system that can be expanded from 41 1/3 inches to 51 1/5 inches. There are no pedals in the cab; proportional servos control the machine. The boom swing and the PTO are controlled by rollers on the joystick.

The unit can run between 6 and 12 hours with a continuous runtime for 5 hours from the power stored in its 48-volt LiFePO4 battery. It fully-charges in 8 hours on 110-volt power or 6 hours with 220-volt service. It weighs 3,643 pounds has 3,608 pounds of breakout force and 2,012 pounds of digging force.

Cratos Equipment sets the standard for battery-powered construction equipment.
