Introduction
Special vehicles are a category of vehicles designed to perform specialized tasks under extreme operating conditions. This includes specialized equipment vehicles for field operations, communications support, and photoelectric detection, as well as civilian special shelters and work vehicles for emergency rescue, power supply support, environmental monitoring, mobile broadcasting, and high-altitude operations.
For a long time, hydraulic systems have been the mainstream solution for upper-body actuators on special vehicles. However, pain points such as oil leakage and contamination, complex piping, unstable low-temperature performance, high noise, difficulty in intelligent integration, and cumbersome field maintenance have constrained equipment upgrades.。
With the electrification and digitalization of equipment, servo electric cylinders are emerging as the preferred alternative and upgrade to hydraulic solutions. Jiangsite servo electric cylinders, leveraging roller/ball screw transmission, servo closed-loop control, and bus integration capabilities, can adapt to both military specialized equipment and civilian special vehicles, providing highly reliable linear motion solutions for various scenarios.
Applications in Specialized Equipment Vehicles
1. Automatic Leveling Support Legs for Shelters
Multi-point synchronous leveling before operations for communications support vehicles, command support shelters, and photoelectric detection vehicles. Supports virtual leg detection and independent closed-loop control of each leg. Heavy-duty servo electric cylinders can be customized with large thrust specifications (Jiangsite high-thrust electric cylinders with maximum thrust up to 500 tons), stable positioning, eliminating hydraulic power stations and complex piping, and significantly reducing on-site setup time.
2. Attitude Drive for Antennas and Photoelectric Turrets
itch stabilization and fine angle adjustment for communication antennas and photoelectric detection equipment, achieving high repeatable positioning accuracy and smooth low-speed operation. Maintains real-time positioning on bumpy roads, dynamically compensating for attitude deviations to help maintain alignment accuracy for detection and communications.
3. Drive for Lifting Mechanisms, Protective Covers, and Cabin Doors
Vehicle-mounted lifting frames, protective shielding covers, and equipment cabin door lifting and locking, equipped with flexible buffering, soft start-stop, and thrust overload protection to reduce structural damage from impact loads. Jiangsite multi-stage cylinders and integrated electric cylinders are available to fit the narrow installation spaces on vehicles.
4. Execution Units for Unmanned Special Vehicles
Robotic arm joints, clamping mechanisms, and lifting platforms for unmanned inspection vehicles, special operation robots, and inspection vehicles. Direct bus connection to vehicle controllers enables programmable position, speed, and force control, supporting remote operation, status feedback, and operational condition monitoring, empowering equipment unmanned upgrades.
5. Vehicle-Mounted Simulation Test Platform
Six-degree-of-freedom motion simulation platform serving as the test execution unit for complete vehicles, control systems, and suspension systems. Excellent multi-cylinder synchronization performance and fast dynamic response, reproducing complex operating conditions such as off-road bumping and tilting for equipment testing and calibration.

Pitch fine-tuning for spectrometers, cameras, and detection sensors mounted on environmental monitoring, laser inspection, and mobile mapping vehicles.
Servo closed-loop accuracy is stable and unaffected by oil temperature fluctuations. Can link with data acquisition systems to maintain fixed-point attitude and support data recording.
4. Auxiliary Actuators for Emergency Repair
Drainage diversion baffles, obstacle clearing clamping and locking mechanisms, power bypass operation tooling, and rescue stretcher lifting and locking.
Supports force control mode with controllable clamping force, reducing the risk of damaging cables and pipes. Supports local button control, remote control, and host computer remote operation.
5. Support for New Energy Civilian Special Vehicles
Adapted for energy storage shelters, inspection vehicles, and mobile charging vehicles modified with new energy chassis. Jiangsite servo electric cylinders can interface with vehicle electronic control systems, simplifying the upper-body architecture, helping reduce overall vehicle energy consumption, and supporting the new energy transformation of special vehicles.
Core Value
Whether for specialized military equipment or civilian special vehicles, Jiangsite servo electric cylinders go beyond the concept of "simply replacing oil cylinders," creating value for complete vehicle upgrades from the dimensions of safety, control, structure, maintenance, environmental protection, and electrification.
1. Safe and Reliable, Eliminating Leakage Risks
• No hydraulic oil or high-pressure oil lines, fundamentally eliminating risks of oil leakage, fire, and environmental pollution;
• Lower operating noise, suitable for noise-sensitive scenarios such as nighttime emergency repair, residential areas, and broadcast studios;
• Supports IP67/IP68 high-protection customization, with corrosion resistance, wide-temperature lubrication, and anti-vibration reinforcement, adapting to harsh environments such as plateaus, deserts, coastal high-humidity areas, cold regions, and water source protection zones.
2. Precise Closed-Loop Control
• Position, speed, and thrust are independently controllable, with control accuracy insensitive to changes in oil temperature and ambient temperature;
• Supports multi-cylinder synchronization, flexible motion, and force control modes with soft start-stop buffering to reduce impact;
• Equipped with bus interfaces for direct integration into the complete vehicle control system, real-time upload of operational data, enabling condition monitoring, fault warning, and remote operation, meeting digital and intelligent equipment requirements.
3. Streamlined Structure, Weight and Space Savings
• Eliminates hydraulic stations, oil tanks, accumulators, valve blocks, and extensive piping, resulting in higher system integration;
• Direct, folded, and multi-stage telescopic cylinder structures available to fit narrow vehicle installation spaces;
• Helps reduce weight and streamline layout, improving vehicle payload and range, with lower modification difficulty for existing special vehicles.
4. Easy Maintenance, Reduced Costs
• No need for regular replacement of hydraulic oil, filters, or seals, significantly reducing field maintenance workload. Long-term comprehensive costs are superior to hydraulic solutions.
5. Low-Noise and Clean, Suitable for Sensitive Civilian Scenarios
• Noise is primarily generated during motion; compared to continuously running hydraulic pumps, operating noise is lower, making it suitable for noise-sensitive scenarios such as residential areas, scenic spots, nighttime emergency repair, and broadcast studios;

6. Native Electrification, Aligned with Development Trends
• Compatible with vehicle-mounted low-voltage/high-voltage power systems, adapting to the development direction of hybrid and fully electric special vehicles;
• Domestic solution reduces supply chain dependency, aligned with the direction of autonomous and controllable equipment development.
The special vehicle industry is simultaneously advancing two upgrade tracks: military specialized equipment is evolving toward high reliability, autonomy, unmanned intelligence; while civilian special vehicles are transforming toward cleaner, quieter, and new energy solutions.
Hydraulic drive was long the industry's standard answer, while servo electric cylinders are emerging as the new solution.
Jiangsite servo electric cylinders, deeply engaged in the field of linear actuators, simultaneously cover both military specialized equipment and civilian special vehicle markets, leveraging modular, high-protection, digital electric servo solutions to support the quality upgrade of various special vehicles.
