Manual coil flipping carries extreme handling risks. This 3-Ton Hydraulic Coil Upender by Gradin Lifts safely rotates 3-Ton to 15-Ton loads 90° in 60 seconds.
Integrated Gravity Roller Bed: Built with a 700 x 700 mm steel roller section on the first deck, enabling low-friction sliding and close alignment against the vertical support plate.
Movable Secondary Platform: Features an adjustable 1300 x 1300 mm loading deck that allows operators to safely insert lifting tools or coil rams prior to resetting the cycle.
Structural Safety Lockouts: Equipped with pipeline velocity-fuse check valves and an overpressure relief system that instantly locks the platform if hydraulic pressure drops.

The load-bearing base frame of our 3-Ton Hydraulic Coil Upender is constructed of Q235 carbon steel rectangular tubes measuring J160 x 80 x 4 mm, delivering high torsional resistance. The dual-deck platform assemblies are sheeted with 4 mm thick steel plates, reinforced internally with Q235 channel girders. The primary tilting motion is guided by a Φ 85 mm solid 45# carbon steel pivot shaft, which is precision-lathed and mounted within heavy-duty self-lubricating bronze sleeve bearings to eliminate structural misalignment.
Fluid power is distributed through two heavy-duty double-acting hydraulic cylinders manufactured by Hengyu Group, featuring a Φ 90 mm bore and Φ 70 mm chrome-plated piston rod. Driven by a 4 kW high-pressure hydraulic gear pump pack, the electro-hydraulic system delivers smooth, uniform angular force. To ensure zero-leakage performance under high-frequency factory duties, the cylinders are outfitted with high-durability Japanese NOK seal kits, preventing hydraulic bypass and preserving system pressure under continuous load cycles.
The primary platform of this FZPT-3000 system features a built-in 700 x 700 mm unpowered roller table with heavy-walled steel rollers. This layout allows operators to slide heavy coils horizontally, aligning the end face tightly against the secondary platform to reduce shear forces on the pivot joints. To prevent dynamic load shifting, a structural strapping bracket is welded to the side of the 1600 x 1300 mm deck, allowing operators to run heavy nylon tie-down straps over the coil body, securing its center of gravity throughout the 90-degree rotation.
System sequences are governed by an integrated Siemens PLC control cabinet paired with Delixi power contactors and thermal overload relays. The secondary 1300 x 1300 mm platform is engineered with a movable hydraulic linkage that repositions the deck during the upending cycle. This unique mechanical feature provides empty space for overhead crane hooks or automated coil rams to insert into the coil’s core. Once the lifting tool is positioned, the PLC controls the cylinder to return the platform to its rest position.
Your Problem: Manually sliding slit steel coils off slitters is extremely labor-intensive, damages thin roll edges, and risks worker injury during the vertical 90-degree lift.
Gradin Solution: FZPT-3000 embeds a zero-friction gravity roller deck on the platform. Workers easily slide the slit coils across, strap them securely, and execute a safe, automated 90° flip in 60 seconds without heavy lifting.
Your Problem: Standard overhead crane slings and clamps focus high radial pressure on single points, easily warping or tearing the outer layers of delicate copper foil, aluminum foil, or paper film rolls during uprighting.
Gradin Solution: Our flat, non-abrasive rolling platform lifts the entire outer surface of the foil roll uniformly. It completely eliminates point-loading, ensuring zero edge-crimping or surface damage for sensitive web materials.
Your Problem: Standard fixed upenders block crane hook insertion. Operators are forced into dangerous, time-consuming manual rigging maneuvers to slide C-hooks into the coil core.
Gradin Solution: The FZPT-3000’s secondary platform automatically retracts after the 90° turn. This creates an open clearance slot, allowing the overhead crane C-hook to slide directly into the coil core without colliding with the steel table.
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.
