Electric machines are increasingly being integrated into construction equipment as part of a broader trend towards electrification in various industries. The adoption of electric power in construction equipment offers several advantages, including reduced emissions, improved efficiency, lower operating costs, and enhanced performance.
Volvo introduced Electric machines in commiting to achieve Net-zero emssions.
The path to net zero - Creating a carbon-free future is a vision that Volvo CE shares with many customers and the company is committed to reaching net-zero emissions by 2040. In addition, as part of its science-based targets, the company is committed to reducing emissions from its product range by 30% by 2030, and reducing emissions from operations by 50% in the same timeframe.
The ECR25?Electric compact excavator is a 2.6-2.8?t capacity machine with a 22.3?kN breakout force. It has an onboard charger for general charging, an external quick charger (optional for indoor/outdoor specifications), and a 20-kWh battery array, allowing for 3?- 4?hours of work per charge. The machines come with an integrated onboard, standard charger, and a range of optional, standalone fast chargers for both indoor and outdoor use
The L25?Electric compact wheel loader features a 2.1?t payload and a maximum speed of 20?kph. The machine comes with a 40kWh battery pack and is expected to deliver 6?- 8?hours of work per charge. Both machines offer near-silent operations and zero emissions while enhancing operator comfort thanks to a working environment that removes the vibrations and noise associated with diesel machines.
The transition to electric machines in construction equipment is driven by the desire to reduce the environmental impact of construction activities, comply with stricter emissions regulations, and improve overall efficiency and performance on job sites. As battery technology continues to advance, we can expect further electrification and innovation in the construction equipment industry.
2. Hydrogen fuel cell:
Volvo CE France, together with colleagues across Volvo Group, will showcase an all-inclusive decarbonization pathway for the entire construction industry that covers powerful battery electric equipment and commercial vehicles, hydrogen fuel cell prototypes, smart services and efficient charging solutions.
Proving that multiple technologies are needed to support the industry’s transition, the world’s first prototype hydrogen fuel cell articulated hauler, the HX04, will also be highlighted, alongside other pioneering solutions such as those powered by renewable biofuels.With services taking on a more prominent role at Intermat, 2024?Volvo CE will display Productivity Services such as Connected Map, Task Manager and its pioneering Equipment as a Service model, as well as Parts and Uptime Services such as the CO2?Reduction Program. Volvo Financial Services will be part of the Volvo stand to present its wide offer of financing solutions.
3. Lithium and Hydrogen Forklift :
Bobcat is world famous for an extensive range of compact machines, which are used in construction, the agricultural sector, landscaping, demolition, recycling and many other industries. Bobcat loaders and telehandlers, which can be equipped with attachments such as buckets, grabs, bale clamps, dump hoppers and pallet forks, are often used for material handling and logistics tasks.
The Bobcat range for logistics and material handling now consists of various product lines: a series of diesel forklift trucks with lifting capacities from 2?to 16?ton; a series of LPG forklift trucks with lifting capacities from 2?to 7?ton and a series of electric forklift trucks with lifting capacities from 1.2?to 10?ton. The latter segment also includes a line of electric forklifts with three wheels for light work from 1.2?to 2?ton. The warehouse solutions include pallet trucks, stackers and reach trucks. The new B80NS forklift truck was on display, which is part of a series of electric counterbalanced forklift trucks with lifting capacities of 8?and 10?ton. In addition, the three wheel B18NT electric forklift with a lithium battery and the B30X-7?Plus hydrogen forklift.
4. Portable Compressor:
Bobcat's PA7.4?(7/45) compressor equipped with a generator option being presented in Bobcat colours is part of a complete line of portable compressors, generators and light towers that now form part of the Bobcat range, building on decades of success and experience in the portable power market. The PA7.4?(7/45) compressor-generator will appear alongside one of the models from the expanding range of electric compact excavators and loaders now available from Bobcat.
Designed with a focus on simplicity, durability, reliability and transportability, the PA7.4?(7/45) compressor-generator provides 4.0?m3/min (140?cfm) of compressed air at 7?bar nominal pressure. Like all Doosan portable compressors, there is a wide range of options and customizations available for the PA7.4?(7/45) to meet customer needs.
The addition of the portable power range products is the latest broadening of the Bobcat product portfolio, which has grown significantly over the past five years, launching more machines during this period than previously in its entire history.
Bobcat has since launched the larger E19e electric mini-excavator featuring the same profile, external dimensions and comparable performance as the popular E19?mini-excavator. Like the E10e, the E19e boasts the same stability, lift capacity and breakout forces as its conventional counterpart, while its constant torque curve (a feature of electric motors) ensures dependable and powerful operations. With a width of just 98?cm, this electric model is easy to operate in even the most confined workspaces, making it ideal for tasks such as demolition as well as outside applications that require quiet, zero-emission operations.
5. Electric Excavator with lithium-ion battery:
Komatsu Ltd, plans to introduce the 13-ton class PC138E-11?electric excavator equipped with a lithium-ion battery to the domestic market as a rental machine in January 2024?or later. By equipping a high-capacity lithium-ion battery and integrating a cooling system for the battery and electric components for this new machine, Komatsu has achieved long operation time while reducing the rear-end swing radius.
Hydraulic excavators are the most versatile type of construction equipment, and the 13-ton class is used in a wide range of jobsites and applications, centering on relatively confined spaces, such as urban civil engineering. By capitalizing on the launch of this machine, Komatsu is set to develop a broad range of new customer needs and establish the market for electric construction equipment.
At Intermat 2024, Komatsu Europe will present the PC138E -11?excavator with a Smart Construction 3D Machine Guidance kit, a simple and flexible technological enhancement now available for a broad range of Komatsu machines. The kit provides an accessible way to add 2D and 3D machine guidance and can be customized with various options that allow the kit to better accommodate each customer's machine configurations and operating conditions.
