The electrification of construction machinery is coming, and leading companies have begun to deploy new technologies
Komatsu Group, one of the world's largest construction machinery and mining machinery manufacturers, recently announced that it will work with Honda to develop a small electric excavator. The smallest model of Komatsu excavators will be equipped with Honda's removable batteries, and the electrification product will be launched as soon as possible.

At present, Sany Heavy Industry and Shanhe Intelligent are also accelerating the transformation to electrification. The electrification storm in the construction machinery industry will bring huge opportunities to related fields.
CITIC Securities analyzed that these manufacturers put the exploration of energy conservation and emission reduction on component-level technology (engine electronic control technology, new electronic plug-in structure multi-way valve, mechanical-hydraulic continuously variable transmission), system-level technology (new transmission form, DCC direct drive hydraulic technology), new energy construction machinery (new energy technology, hybrid technology) and achieved good energy-saving effects and achieved environmental protection goals.
On the basis of electrification, many listed companies are making intelligent attempts. Sany Heavy Industry has launched a new generation of SY375IDS intelligent excavator. The product is equipped with functions such as intelligent weighing and electronic fences. It can monitor the weight of each bucket in real time during work, and can also set the operating height in advance to prevent improper operation from causing damage to underground pipelines and overhead high-voltage lines.
Recently, Shanhe Intelligent SWE240FED electric intelligent excavator rolled off the production line in Shanhe Industrial City, Changsha Economic Development Zone. In the company's view, electric and intelligent will be the future development direction of engineering machinery products. With the increase of battery energy density and the decrease of cost, the application of electric intelligent excavators will be more extensive.
Kong Lingxin, an analyst of CICC's high-end equipment manufacturing group, believes that electrification in the field of low-power small and medium-sized machinery is a long-term development trend. Taking the forklift industry as an example, the shipment of electric forklifts accounted for about 30% of the industry from 2015 to 2016. By 2020, the shipment ratio of internal combustion forklifts and electric forklifts has reached 1:1, and electric forklifts have an additional 20% market increment.
Kong Lingxin said that small or micro excavators with medium and low tonnage below 15 tons also have the possibility of large-scale application. At present, the number of small excavators and micro excavators in China accounts for more than 20% respectively, and the total social ownership is about 40%, but this is by no means the ceiling. Referring to Japan, the social ownership of small excavators and micro excavators accounts for 20% and more than 60% respectively, and the total of the two is close to 90%. The increase in the electrification rate will also bring about further growth in the entire electric excavator market.
