The challenge of recharging power during tunnel construction
1. Power grid coverage is weak in remote, rural areas.
Tunnels are often located in remote, off‑grid areas, where grid connection is difficult and costly. Moreover, the confined, damp, and dusty tunnel environment poses harsh working conditions: fixed charging stations cannot be installed, and even temporary setups are prone to damage, making reliable energy replenishment impossible.
2. Temporary cabling poses numerous risks and is inconvenient to maintain and operate.
To address the challenge of energy replenishment, some project teams have adopted a temporary cabling approach. However, the confined working space inside the tunnel, combined with the cluttered cable layout, makes the cables susceptible to impacts and abrasion from electric rock‑drilling rigs, loaders, and other equipment, thereby increasing the risk of electrical leakage, fires, and other safety incidents.
3. Dynamic changes in construction locations are increasing the difficulty of energy replenishment.
Tunnel excavation is advancing dynamically, with construction fronts continuously extending deeper and remaining mobile; conventional energy‑replenishment methods cannot flexibly adapt to these shifting locations, resulting in extremely poor compatibility.
4. Equipment transportation and charging are time-consuming and labor-intensive, delaying the project schedule.
If electric multi‑function drilling rigs, electric rock‑drilling rigs, and similar equipment are frequently transported to off‑site charging stations for recharging, this not only requires substantial manpower and resources but also disrupts construction operations, significantly slowing progress and becoming a critical bottleneck in the deployment of new‑energy tunneling projects.
Addressing the core pain points outlined above, Ruisu Intelligent’s 5 MWh mobile charging‑and‑storage vehicle breaks free from conventional energy‑replenishment constraints by pioneering a “flexible adaptation and bi-directional energy supply” model. It can seamlessly navigate narrow tunnels to deliver power to on‑site equipment at close range; in special circumstances—such as limited space deep within the tunnel or when deployment at the portal is more convenient—it can park outside the tunnel and provide power to in‑tunnel devices via long‑distance cabling. This delivers seamless energy replenishment both inside and outside the tunnel, effectively resolving the longstanding challenge of powering new‑energy equipment in tunnel environments.

Ruisu 5 MWh Mobile Charging and Storage Vehicle
Why has it become the top choice for tunnel construction power supply?
🚛This storage-and-charging vehicle utilizes Integrated compact design , with a flexible form factor and rapid deployment, Can be moved anytime, anywhere. , effortlessly entering narrow tunnels, flexibly adjusting its parking position to follow construction site markers, and refueling equipment at close range;
⚡️ The charging and storage vehicle is equipped with a cable reel. ， The charging cable is available in customizable lengths, allowing you to easily adjust its length as needed. It can both meet the long-distance power supply requirements of tunnel excavation and avoid cable clutter, thereby saving working space; when encountering narrow tunnels that are difficult to pass through, the energy storage vehicle parks at the tunnel entrance and delivers power into the tunnel via a long cable. ， Enables convenient energy replenishment—vehicles park outside the tunnel while power is delivered inside—suitable for a wide range of tunnel construction scenarios.
⚙️ Dedicated accompanying cable Wear-resistant and tensile-resistant, dustproof and moisture-proof It can reliably handle the complex operating conditions—humid and dusty environments inside tunnels, as well as wind and sun exposure outside—while preventing cable damage, eliminating the need for cumbersome in-tunnel wiring, and significantly reducing project costs.
🔋 5 MWh large-capacity energy storage system, paired with a multi-gun configuration. It can simultaneously provide charging services to multiple new-energy vehicles, effortlessly handling the load pressure associated with concentrated charging and significantly boosting charging efficiency while preventing vehicle queues that could delay project timelines.
This energy storage vehicle is precisely compatible with mainstream brands currently available on the market. All-electric multifunctional drilling rig, all-electric rock‑drilling rig, all-electric loader to meet electricity demand and achieve full-process energy replenishment coverage for tunnel construction.
In the initial stages of tunneling, it can provide power to all‑electric drilling rigs and loaders, helping to swiftly complete site leveling and borehole preparation.
During the mid-term core tunneling phase, continuous and stable power supply ensures the efficient operation of all‑electric rock‑drilling rigs and drilling machines.
During the final phase, we provide power replenishment for all‑electric loaders, supporting material handling and waste‑slag removal, ensuring the equipment operates at full capacity throughout.
