Executive summary
The machine on this page is our 180° pallet inverter with double clamps, an industrial load turner engineered for complete pallet load inversion rather than single-plane coil upending. A coil upender tilts a coil through 90°, transitioning between eye-horizontal and eye-vertical. The 180° inverter clamps an entire palletized load between two clamp plates and rotates it 180° upside down. The FPFZ-C02 handles 1.5 t loads in approximately 25 s per turn, and a heavy-duty 2.0 t version is engineered for higher payload demands.

90° upending vs 180° turning
| Machine | Turn | Typical load | Why |
|---|---|---|---|
| Coil upender | 90° | steel, wire or copper coils | change the coil from eye-horizontal to eye-vertical for storage, packing or a decoiler |
| Mold upender | 90° | dies and molds | open or service a heavy mold from the side |
| 180° pallet inverter | 180° | pallet loads, stacks of pallets or panels | change or remove the pallet, reach the underside, or invert the product |
A 90° upender tilts a load resting on a cradle or platform table through a single quadrant. In contrast, a 180° inverter must rigidly support the load from opposing faces throughout the entire rotation arc, ensuring total load integrity when fully inverted. That continuous bilateral support is provided by the synchronized double-clamp mechanism.
How the double-clamp inverter works
- Load. A forklift or powered pallet truck places the full load onto the lower support plate. The base sits flush at floor level for direct, roll-in loading.
- Clamp. The upper clamping plate lowers onto the load. Twin-clamping technology with adjustable hydraulic clamping pressure secures the product without crushing fragile goods [manufacturer rating]. Built-in safety sensors detect proper load alignment before rotation can be initiated [manufacturer rating].
- Turn. The rigid structural frame rotates 180° via a hydraulic drive unit. Turning speed is adjustable, delivering smooth, vibration-free motion throughout the cycle. An integrated load-locking mechanism prevents product shifting or dislodgement during the turnover arc [manufacturer rating].
- Release. The plate that was originally at the bottom now rests at the top and retracts upward, leaving the inverted load fully supported on the lower plate.
- Unload. The forklift retrieves the inverted pallet load, or an exchange pallet is introduced to execute a secondary transfer cycle.
Heavy-duty mechanical travel stops and electrical limit switches terminate rotation precisely at 180°, protecting hydraulic cylinders and bearings from shock loading. The operator manages all motions from a standalone main control panel or via a wireless remote control outside the perimeter zone.
What 180° turning is used for
- Pallet exchange. Transferring goods from internal factory wood pallets to hygienic plastic, aluminum, or fumigated export-grade pallets, or extracting broken pallets to protect automated storage systems.
- Pallet-less loading. Removing the pallet entirely prior to container loading, allowing high-density, double-stacked container stuffing while retaining high-value captive pallets within the facility [manufacturer rating].
- Load recovery. Safely righting tilted, shifted, or inverted product stacks without manual restacking labor or secondary damage.
- Stacked panels and components. Inverting dense stacks of sheet materials, panels, or empty pallet nests to perform bottom-side quality inspections, surface trimming, or reverse-order processing.
Specifications
| Item | FPFZ-C02 (1.5 t) | 2.0 t version |
|---|---|---|
| Load size | 1,100 × 1,200 mm | L/W 1,000–1,200 mm |
| Load height | 1,400–2,000 mm | 610–2,000 mm |
| Turnover capacity | 1.5 t | 2.0 t |

| Power supply | 380 V, 50/60 Hz, 3 ph | 380 V, 50/60 Hz, 3 ph |
| Control | panel and wireless remote | panel and wireless remote |
| Options | fence, laser beam, ramp | confirmed at quote |
Body and base frames are fabricated from welded structural steel profiles. Fixing to the floor is by dead weight. Installed motor power figures depend on the specific hydraulic power pack fitted for the cycle speed requirements, and motor ratings are finalized during engineering quotation.
Worked example: turns per shift
The following model evaluates an export facility exchanging internal wooden pallets for plastic shipping pallets on individual palletized units [illustrative].
| Step | Calculation | Result |
|---|---|---|
| Turn time | quoted | about 25 s |
| Forklift in and out, clamp and release (illustrative) | estimate | about 95 s |
| Cycle per load | 25 + 95 | about 120 s |
| Loads per hour | 3,600 ÷ 120 | about 30 |
| Loads per 8 h shift at 80% use | 30 × 8 × 0.8 | about 192 |
Result. The mechanical 180° rotation occupies only a fraction of the total cycle; forklift staging and pallet positioning dominate overall production throughput. Optimizing staging logistics, fork truck cycle routes, and pallet buffering yields a greater throughput increase than attempting to accelerate turnover rotation speed.
Selection checklist
- Maximum payload gross weight, including pallet and packaging tare.
- Minimum and maximum load height range (daylight opening between plates).
- Primary operational objective: pallet transfer, pallet removal, or load inversion.
- Material handling method: counterbalance forklift, reach truck, or manual pallet jack (determines ramp requirement).
- Target hourly capacity and duty cycle requirements.
- Guarding: fence or laser beam.
Safety: EN 415-10 and ISO 12100
Stationary pallet inverters are categorized under packaging and handling machinery standards governed by EN 415-10, with formal risk assessments performed in accordance with ISO 12100:2010. Primary mechanical hazards include rotating frame pinch points and bilateral clamping plate crush zones.
Operators remain outside the turning zone, working from the standalone control panel or the wireless remote. A fence or a laser beam guard is available, and rotation is electrically interlocked: optical sensors verify proper load alignment before turnover drive initiation is permitted [manufacturer rating]. An emergency stop is provided, and guarding and CE documents are agreed per project.
Engineering FAQ
Q: How long does one turn take? A: Approximately 25 s for the complete 180° inversion.
Q: Does it need a pit? A: No. The machine features a surface-mounted, floor-level base. A low-profile steel approach ramp is available for operations utilizing manual or powered pallet jacks.
Q: Can it turn a coil? A: No. Round industrial coils require a dedicated 90° coil upender equipped with a V-cradle table to prevent radial rolling and surface deformation during rotation.
Q: What power does it need? A: Standard industrial 380 V, 50/60 Hz, three phase.
