How to Select Lifting Equipment for Energy Storage Stations
In a nutshell: Kelude Heavy Industry provides a complete crane configuration solution for energy storage power stations, covering four key work areas: battery racks, PCS converters, main transformers, and maintenance zones. Designed for lifting capacities from 2 to 20 tons and spans from 10 to 30 meters, the total crane equipment investment ranges from approximately $22,000 to $222,000. The battery rack area uses a 5–10t LD-type explosion-proof single-girder electric crane with insulated lifting spreaders; the PCS area is equipped with a 3–5t electric hoist bridge crane; the main transformer zone relies on a 25t truck crane for positioning; and the maintenance area features a 1–2t jib crane. This covers every hoisting need of an electrochemical energy storage station, from equipment installation to routine maintenance.
Crane Solutions for Energy Storage Stations
Battery Rack Area | PCS/Converter Zone | Transformer Area | Maintenance & Inspection Zone
Energy storage stations — including standalone storage facilities and renewable-plus-storage projects — require cranes for a wide range of tasks: precise, lightweight lifting of battery racks; installation of electrical equipment in the PCS converter area; outdoor placement of large main transformers; and flexible hoisting in maintenance zones. Kelude Heavy Industry delivers complete lifting solutions for energy storage stations, from battery racks to main transformers, covering the full range from 1t to 80t.

Battery Stack Lifting: Key Considerations
An energy storage battery stack consists of multiple battery clusters connected in parallel, with each cluster weighing between 500 kg and 2 t. Battery modules are highly sensitive to electrostatic discharge, so LD-type single-girder bridge cranes and electric hoists are fitted with anti-static slings and anti-static wheel assemblies to prevent ESD damage to the Battery Management System (BMS). Kelude's anti-static upgrade solution includes conductive rubber wheel covers, static grounding wires, and anti-static coating on lifting spreaders, meeting the ESD cleanroom requirements of the S20.20 standard.
PCS Converter and Transformer Area Configuration
Each PCS (Power Conversion System) unit weighs 2–8 t and is classified as precision electrical equipment, demanding strict shock-proofing and micro-motion alignment during installation. Kelude recommends equipping LD-type cranes with variable-frequency speed control and micro-speed hoisting to keep PCS installation deviation within ±5 mm. Main transformers, each weighing 10–40 t, must be positioned on outdoor foundations; this is handled by QD-type double-girder bridge cranes (indoor) or MG-type gantry cranes (outdoor) with specialized spreaders.
Integrated Crane Strategy for Energy Storage Plants
Given the short construction cycle and concentrated equipment deliveries typical of energy storage plants, a unified supply solution for all lifting equipment across the site is recommended. Kelude can develop a coordinated crane plan—from battery stacks to main transformers—tailored to plant capacity (10 MW / 50 MW / 100 MW) and layout (centralized or distributed). This approach reduces the complexity of managing multiple equipment brands and cuts overall project lifting equipment costs by approximately 15%.

FAQ
Q: What anti-static requirements do energy storage battery racks impose on cranes?
A: Battery components are highly sensitive to electrostatic discharge (ESD), which can damage sensitive electronic elements in the BMS (Battery Management System). Kelude's anti-static solution includes conductive rubber wheel sleeves (grounding resistance <10Ω), stainless steel anti-static lifting slings, and conductive coating on lifting spreaders, ensuring the crane neither generates nor accumulates static charge during operation.
Q: What precautions should be taken when hoisting the main transformer at an energy storage power station?
A: A single main transformer weighs between 10t and 40t and is an oil-immersed unit. During hoisting, the inclination angle must be kept at ≤15° from horizontal. Kelude recommends a specialized spreader with a four-point lifting arrangement for even load distribution, equipped with tilt angle monitoring sensors. Anchor bolt holes must be pre-positioned in the foundation, and the bearing capacity of the foundation must be verified to be ≥150kPa before lifting begins.
Q: What accuracy requirements does PCS converter installation impose on the crane?
A: The PCS converter must be positioned on a concrete foundation with multiple anchor bolt holes at its base. Kelude's variable-frequency speed control with micro-motion capability enables ultra-slow hoisting speeds of 0.2–0.5 m/min. Combined with a laser positioning assist system, installation deviation can be controlled to within ±5 mm.
Q: What lifting equipment is needed for small to medium energy storage power stations (below 10 MW)?
A: Energy storage stations below 10 MW typically use containerized or prefabricated cabin designs, with the primary lifting needs centered on unloading and positioning equipment upon delivery. The recommended configuration includes one 5t–10t LD Type crane for battery rack maintenance, one 25t truck crane (rented) for positioning the main transformer and PCS units, and one jib crane (1t–2t) for the maintenance area.
