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 spaces.
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.

Surface integrity is maintained through the application of natural cork on all contact surfaces. Cork was chosen for its unique properties: it offers a high coefficient of friction while remaining soft enough to prevent scratches or breakage on the glass. This choice of material ensures a secure grip with high clamping pressure.
No. These instruments are engineered exclusively for indoor industrial use. 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).
The primary differentiation lies in the jaw aperture and height. The P12C "Short" is a specialized tool for thinner sheets (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.
Lubrication and mechanical overhaul: periodic inspection and lubrication of the mechanical parts and replacement of worn components.
While the mechanical principle of a scissor clamp can apply to various materials, Schiavo clamps are designed for lifting glass sheets. 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.
At Schiavo, we believe that the best industrial solutions are not simply sold, they are built through collaboration. Our team of designers and technicians is ready to work alongside you to find the perfect balance between your operational vision and our engineering solutions.
