Schiavo lifting clamps are designed to solve the main challenge in glass logistics: moving heavy, fragile sheets quickly without compromising operator safety or causing material damage. With a lightweight yet robust mechanical structure, these clamps ensure a secure grip that adapts to the thickness of the glass.
Designed for facilities with low ceiling heights or bridge cranes with limited vertical travel. By reducing the distance between the crane hook and the glass grip point, this series allows for the safe vertical movement of large-format sheets in confined spatial environments.
Designed to meet the daily demands of glass-processing plants, the Standard series offers a reliable mechanical grip for monolithic and laminated sheets. It is the ideal solution for transferring glass from the sorter to the cutting table or to the vertical washing lines, ensuring maximum efficiency in the operating cycle.
Specifically designed for thick architectural laminated glass. This series features extended jaw kinematics to maintain a parallel pressure distribution across wider profiles, ensuring secure transport of multi-layered glass assemblies.

All units are fully CE certified and designed in full compliance with current safety directives, ensuring long-term reliability and operational risk reduction.
The Schiavo clamp series is engineered for modularity, catering to a broad spectrum of glass thicknesses and load requirements. The range begins with the compact P12C (500 kg capacity) and extends to the heavy-duty P40-2000, capable of securing loads up to 2,000 kg.
| Model | Capacity (kg) | Glass Thickness (mm) | Unit Weight (kg) |
| P12C | 500 | 3 – 12 | 20 |
| P20 | 1,000 | 3 – 20 | 30 |
| P25 | 1,000 | 10 – 30 | 30 |
| P40 | 1,000 | 20 – 40 | 30 |
| P40-2000 | 2,000 | 20 – 40 | 30 |
Surface integrity is maintained through the application of natural cork on all contact surfaces. Cork is selected for its unique cellular structure, which provides a high coefficient of friction while remaining soft enough to prevent scratches or micro-abrasions on the glass. This material choice ensures a secure grip without compromising the optical quality of the glass, even under high clamping pressure.
No. These instruments are engineered exclusively for internal industrial usage. The mechanical tolerances and material compositions are optimized for stable, indoor factory environments (e.g., moving glass from racks to cutting tables or edging lines). Using these clamps in outdoor environments—where wind loads, moisture, and temperature fluctuations can affect grip stability—is strictly discouraged as it falls outside the intended engineering scope.
The primary differentiation lies in the jaw aperture and height. The P12C "Short" is a specialized tool for thinner lites (up to 12 mm) and lower weight profiles, weighing only 20 kg for easier manual positioning. The P20 through P40 series share a larger chassis (750x250x800 mm when closed) to accommodate deeper glass profiles and provide the structural mass necessary to stabilize loads up to 1,000 kg or 2,000 kg.
To ensure operational safety, the following maintenance protocols are standard:
Surface Inspection: Daily verification that the cork pads are clean and free of glass shards or debris.
Friction Material Replacement: Cork pads must be replaced immediately if they show signs of compression set or thinning, as a reduced thickness directly impacts the clamping force.
Mechanical Lubrication: Periodic inspection and lubrication of the scissor-action pivot points to ensure smooth opening and closing cycles.
While the mechanical principle of a scissor clamp can apply to various materials, Schiavo clamps are calibrated for the specific hardness and density of glass. Using them for more porous or flexible materials may result in inadequate clamping force or damage to the material. For non-glass applications, a specific technical evaluation by the engineering department is required.
