This 5-Unit Synchronized Lift acts as a high-stability vertical positioning network designed for the synchronized handling of oversized or non-uniform industrial payloads. Built by Gradin as a custom engineered-to-order (ETO) solution, the system integrates five independent lifting columns into a single, unified control logic, ensuring that the entire platform or workpiece remains perfectly level within sub-millimeter tolerances during transit. Engineered for high-intensity 24/7 duty cycles, the lift eliminates the structural stress and “tipping” risks associated with traditional single-point or dual-point lifting of long-span components. Whether utilized for the assembly of railcar frames, wind turbine blades, or large-scale aerospace structures, this 5-Unit Synchronized Lift provides a stable, vibration-free interface that can be fully integrated into a plant-wide automation system for repeatable, mission-critical production sequences.

FEA-Validated Multi-Point Structural Stability
Lifting oversized loads across a 5-unit footprint creates massive torsional stress and potential mast sway. Every Gradin 5-Unit Synchronized Lift undergoes rigorous Finite Element Analysis (FEA) to simulate high-tonnage eccentric loading.
Torsional Stress Management: We utilize reinforced high-tensile steel columns engineered to maintain absolute rigidity across long spans.
Zero-Deflection Engineering: Our mast and carriage designs ensure that even with 100-ton loads, the structure remains perfectly stable at maximum vertical extension.
Dynamic Load Balancing: By analyzing stress distribution at every pivot point, we prevent mechanical fatigue, providing a reliable vertical conduit for your high-value assets.
Precision Multi-Axis Synchronization Logic
When handling sensitive aerospace or wind energy cores, synchronization is the foundation of safety. The Gradin 5-Unit Synchronized Lift utilizes advanced proportional control technology or synchronized servo-screw drives.
Servo-Sync Precision: Integrated with Siemens S7-1500 PLC logic, our system ensures the 5 units raise and lower with sub-millimeter uniformity (accuracy up to ±0.05mm).
Vibration Control: The drive system is calibrated for a soft-start/soft-stop profile, protecting sensitive internal components from any inertial shock during the lifting process.
Active Deviation Correction: High-resolution absolute encoders provide real-time height data, allowing the control system to adjust the lift tempo of individual units instantly to compensate for load shifts.
Industry 4.0 Connectivity and Metrology Handshake
Modern large-scale manufacturing demands equipment that functions as a smart node within a digital factory. Every Gradin 5-Unit Synchronized Lift is built with an open-architecture control system.
Digital Handshake: Our systems support Profinet, EtherCAT, and 5G connectivity, allowing the lift to communicate directly with your Manufacturing Execution System (MES).
Metrology Integration: The platform can be direct-linked to Laser Trackers (e.g., Leica or Faro), allowing the 5-unit system to automatically adjust its height based on real-time spatial data.
Bespoke Tooling Interfaces: We customize the top platform with integrated turntables, vacuum jigs, or specialized non-marking cradles bespoke to your specific large-component geometry.
[Aerospace] – Large-Scale Fuselage and Wing Section Assembly
The Challenge: Aligning and docking 50-ton aircraft segments where multi-point vertical stability is required for riveting and bolting.
Gradin Solution: The Gradin 5-Unit Synchronized Lift provides a vibration-free vertical transition, ensuring that large fuselage sections are held with sub-millimeter precision across the entire 5-point footprint.
[Wind Energy] – Tower and Nacelle Component Integration
The Challenge: Handling massive tower sections or heavy internal components where load centers are heavily offset and high-tonnage stability is non-negotiable.
Gradin Solution: We customize the FEA-reinforced columns to provide the extreme tonnage required. Our proportional control ensures components are positioned perfectly for ergonomic bolting at height.
[Heavy Industry] – Multi-Story Power Plant Core Assembly
The Challenge: Moving entire industrial turbine cores or large electrical transformers between production levels in restricted factory bays.
Gradin Solution: Acting as a high-capacity vertical link, the Gradin 5-Unit Synchronized Lift replaces unpredictable crane-lifts with a standardized, precision engineering operation, optimizing throughput and safety.
Redundant Safety Architecture and Multi-Point Monitoring Logic
Safety in high-reach, high-tonnage vertical movement is our most critical engineering priority.
Hydraulic Fail-Safe: Every unit is integrated with redundant velocity fuses and anti-burst valves that lock all 5 units instantly if a pressure drop is detected.
Active Perimeter Protection: We offer synchronized safety interlocking with perimeter laser scanners and light curtains—the system executes a controlled halt if an operator enters the hazard zone.
Load-Center Monitoring: Integrated load cells provide constant feedback on weight distribution across all 5 columns, ensuring that the system protects your personnel and your high-value assets throughout every cycle.
For this heavy-duty series, we can engineer load capacities up to [300] tons, with platform dimensions and lifting heights customized to your operational envelope. Requirements exceeding our standard engineering matrix will undergo a Finite Element Analysis (FEA) by our engineering team to ensure structural viability before proposing a solution.
To initiate the engineering proposal, please provide the following baseline data:
Rated Load Capacity
Maximum Lifting Height & Closed Height
Platform Dimensions (L x W)
Duty Cycle (e.g., operational cycles per hour/day)
Environmental Conditions (e.g., indoor/outdoor, washdown, explosion-proof)
Pit depth or overhead clearance constraints
Yes. The control systems can be equipped with standard communication protocols (e.g., Profinet, Modbus, Ethernet/IP) utilizing [Siemens / Allen-Bradley / Omron] PLCs. This ensures seamless I/O signal synchronization with upstream/downstream conveyors, AGV/AMR units, and your central control room.
Every custom unit undergoes a mandatory Factory Acceptance Test (FAT) prior to dispatch. This includes continuous operational testing at 100% rated load, static overload testing at [120% / 125%] capacity, and the physical triggering of all mechanical anti-fall and hydraulic safety interlocks. FAT documentation and video proof are included in your engineering package.
Upon final approval of the General Arrangement (GA) drawings, the manufacturing lead time is typically 4 to 8 weeks. Oversized structural components are engineered with a modular design to fit into standard shipping containers (20FT/40HQ). On-site assembly utilizes pre-engineered bolted flange connections and heavy-duty aviation plugs, strictly eliminating the need for field welding.
We provide a standard [12/24]-month warranty covering the structural frame and primary hydraulic/electrical components. To minimize operational downtime, a comprehensive set of standard consumables (e.g., cylinder seal kits, travel switches, relays) is shipped alongside your equipment. During the warranty period, replacement parts for non-human-induced failures are dispatched via priority air freight (DHL/FedEx) within 48 hours.
Beyond the warranty, we guarantee lifetime engineering support. Your custom equipment's CAD drawings, electrical schematics, and BOM (Bill of Materials) are permanently archived in our system. This ensures you receive uninterrupted remote troubleshooting, maintenance guidance, and exact spare parts matching for the entire lifecycle of the equipment.
