Bobcat promotes fuel cost savings with new E32e and E10e electric compact excavators
By Jenny LescohierJune 01, 2022
On the heels of its January introduction of the T7X, the world’s first all-electric compact track loader, Bobcat now adds two electric compact excavators, the E32e and E10e, to its stable of compact battery-powered alternatives.
Bobcat Company recently showed the capabilities of its electric construction equipment lineup at a series of test drive and live demonstration events near Los Angeles in Granada Hills and in Stockton, CA.
The tour promoted the new machines to leaders from the California Air Resources Board, City of Los Angeles, Port of Los Angeles, Stanislaus County and other public organizations, as well as Sunbelt Rentals, Bobcat dealers and construction contractors as choices for government and private fleets to help reduce carbon footprints and minimize job site noise levels.
With a compact footprint, quiet operation and zero emissions, the new E32e and E10e battery-powered compact excavators operate with performance that equals or exceeds diesel-powered machines, according to Bobcat. The electrical motors deliver full torque, regardless of rpm, providing top productivity, smooth hydraulic control and on-demand multifunctioning performance with no noticeable power drop.
An added benefit is the cost to recharge the battery system is a fraction of the price for a diesel fill-up.
Producing zero emissions, the T7X CTL and electric compact excavators support environmentally sensitive work sites. They allow users to operate inside
structures where diesel exhaust is restricted. There are also significantly lower noise levels and vibration with these machines, which improves job site communication and safety, and allows work in sound-sensitive areas.
The Bobcat electric machines will deliver up to four hours of active work per charge, depending on usage and application. While uses vary, each charge can support common daily work operations and the use of work modes for up to four hours of continuous operation time and a full day of operation during intermittent use or a typical contractor workday, according to the manufacturer.
Bobcat points out that a growing number of companies and individuals support eco-friendly job site practices, and many government agencies are adopting environmental, social and governance (ESG) principles that give priority to contractors with sustainable business practices. Having a battery-powered compact excavator in fleet can help some contractors confidently bid on these opportunities.
E32e and E10e by the numbers
Powered by a lithium ion battery, the 21.6-hp, 7,861-lb. E32e has a 44.5-kWh gross battery capacity. It brings 4,689 lbf. of digging force (arm) and 7,284 lbf to the bucket. Drawbar pull is 7,815 lbf. and travel speed is 1.6 mph (low) and 2.6 mph (high).
Its 24.4-gpm variable displacement piston pump supplies 16.8 gpm of auxiliary flow with 2,987-psi auxiliary relief.
In addition to many of the usual standard features, the E32e comes with Bobcat’s 5-inch display monitor and Mechanical X-Change attachment mounting system.
For its part, the 10.1-hp, 2,647-lb. E10e is powered by a manganese laminated ion battery with a gross capacity of 11.5 kWh. Performance wise, it offers 1,247 lbf. digging force (arm) and 1,864 digging force (bucket). Drawbar pull is 2,226 lbf and travel speed is 1.8 mph high and 1.1 mph low.
A triple gear pump with 6.6-gpm capacity supplies 5.2-gpm auxilliary flow with 2,755-psi auxiliary relief.
Bobcat T7X compact track loader scheduled for delivery in July
With its introduction of the T7X at the Consumer Electronics Show in January, Bobcat was the first equipment manufacturer to commercialize a dedicated all-electric construction machine within the compact size range.
Sunbelt Rentals, a leading equipment rental company with more than 1,050 locations across North America, is the first company to invest in a large fleet of T7X loaders, as well as electric compact excavators. These pieces of equipment are scheduled to be delivered and available for rent by Sunbelt Rental customers in California and at other U.S. locations starting in July.
“We are thrilled to showcase these machines and demonstrate how off-road construction equipment is the next frontier in electric vehicles. They are designed to deliver a smaller carbon footprint and a quieter job site experience but can also outperform their diesel machine counterparts,” said Joel Honeyman, vice president of global innovation at Bobcat.
“These machines offer zero-emissions and clean solutions that meet today’s growing regulations, as well as the high standards of government and construction customers in a variety of applications.”
The Bobcat T7X is the first machine of its kind to eliminate all hydraulic components, emissions and reduced vibrations.
The traditional hydraulic work group has been completely replaced with an electrical drive system consisting of electric cylinders and electric drive motors, which means virtually no fluids. The T7X uses less than one gallon of eco-friendly coolant compared to 57 gallons of fluid in its diesel/hydraulic equivalent model.
