As the national “dual carbon” policy continues to deepen, the electrification of construction machinery has become an inevitable trend in the industry. Electric excavators, crawler cranes, loaders, and other equipment have become widely adopted.
However, many construction project departments have found that: The equipment has been upgraded to electric models, yet the accompanying energy‑replenishment solutions remain woefully behind!
Electric crawler cranes operate in dispersed work environments, require frequent repositioning, and often run for extended periods, placing extremely high demands on the flexibility, stability, and continuity of energy‑recharging. Traditional energy‑recharging methods, however, suffer from numerous unavoidable drawbacks:
To this end, Ruishu Intelligence has launched a brand-new 2–5 MWh mobile energy storage unit, which can address all the pain points of electric crawler cranes in a single vehicle!
With years of deep expertise in the customized mobile energy storage sector, Ruisu has precisely targeted the exclusive energy‑replenishment needs of electric crawler cranes. Introducing a 2–5 MWh high-capacity, customizable mobile energy storage vehicle solution. , specially designed for high‑frequency relocation and all‑weather operation in construction machinery, it completely redefines conventional energy‑replenishment methods, becoming the exclusive “energy partner” for electric crawler cranes.
✅️ Large capacity with flexible configuration, suitable for all operating conditions: Supports multi‑level capacity customization ranging from 2 to 5 MWh, enabling a single unit to meet the all‑weather, continuous energy‑storage needs of one or multiple electric crawler cranes. With ample storage capacity, it eliminates the need for frequent recharging and prevents downtime caused by power interruptions.
✅️ DC fast charging for construction machinery: efficient energy replenishment without disrupting operations. Equipped with an industrial‑grade, high‑power DC fast‑charging interface, it precisely complies with the high‑voltage charging standards for electric crawler cranes, delivering rapid charging and broad compatibility. This enables quick energy replenishment during work breaks, maximizing operational uptime.
✅️ Intelligent all‑area temperature control, ensuring stable operation around the clock: Equipped with an intelligent liquid‑cooling temperature‑control system, it can adapt to extreme high‑ and low‑temperature construction environments, precisely regulating the equipment’s operating temperature to prevent overheating‑induced shutdowns and low‑temperature performance degradation, thereby ensuring 24‑hour stable output from the energy storage system.
✅️ The entire system is mobile and deployable, offering ultra‑flexible on‑the‑go use: Its integrated trailer‑mounted design enables direct towing and relocation, eliminating the need for civil‑engineering infrastructure or pole installation. Once on site, the equipment can immediately begin energy replenishment, perfectly aligning with the high‑frequency relocation requirements of crawler cranes.
Based on calculations for a single 600‑ton‑class electric crawler crane operating under field conditions—300 construction days per year with an average of 10 hours of operation per day—the comparison between conventional energy replenishment and Ruisu mobile energy‑storage‑based recharging reveals the true engineering costs:
1
Traditional diesel generator refueling (an established industry solution)
Fuel consumption, operations, and maintenance: daily energy‑related costs amount to approximately RMB 4,200, with annual total electricity expenses of about RMB 1.26 million. When factoring in noise‑and‑emission compliance upgrades, temporary power‑line installation, and transformer‑rental fees, average annual additional expenditures come to RMB 180,000. Total annual losses amounted to RMB 1.44 million. 。
2
Municipal Temporary Power Direct Charging (Restricted Operating Conditions)
High-voltage connection installation + cable infrastructure construction + transformer rental fees: a one-time upfront investment of RMB 260,000; combined with peak‑hour commercial and industrial electricity rates, the average daily electricity cost is RMB 2,600. Annual electricity cost: RMB 780,000 ; When a construction site relocates, all electrical distribution equipment becomes obsolete, and the cost of reinstalling it is extremely high.
3
Ruisu 2–5 MWh mobile energy storage vehicle recharging
Leveraging valley‑period energy storage to shave peak loads and fill valleys, the average daily comprehensive energy‑cost is approximately RMB 1,550; no transformer installation or high‑voltage cable laying is required, resulting in zero capital‑intensive infrastructure investment; the equipment can be repeatedly relocated and reused across multiple projects. The total annual electricity consumption and operation & maintenance costs amount to RMB 680,000. 。
Account Summary: Compared with diesel power generation , using the Ruisu mobile energy storage vehicle can enable a single crane to directly… per year Cost savings 7 60,000 yuan ； Compared with municipal on-site direct charging , avoid infrastructure sunk costs, Overall cost reduction of 42% The longer the construction period and the more frequent the site transitions, the greater the cost‑reduction benefits.
