Vertical L-Type Props

In N-type models, the vertical alignment is adjusted using a single sleeve, which, depending on the direction of rotation, increases or decreases the extension of the prop.

N-type push-pull props distinguish themselves from other classes by their method of vertical alignment adjustment.

This adjustment is achieved using a single sleeve that, depending on the direction of rotation, increases or decreases the extension of the prop.

The movement of the single sleeve in both directions is possible due to the use of two perforated elements placed inside the grooves of the threaded tube.

The features of the N-type push-pull prop are as follows:

• Adjustable length from 1,80 to 5,00 m, depending on the support model, with a 10 cm increment, using the spheroidal cast iron sleeve;
• Guaranteed tension of 38,00 kN, regardless of the applied extension;
• Anti-shearing system: increased length of the inner tube compared to the outer tube ensures at least a 10 cm difference between the two tubes during the closing phase, preventing accidents;
• Plates mounted on hinges at both ends ensure better adherence, allowing the prop to be fastened and assembled at various angles;
• Tube protection: hot-dip galvanization, in accordance with the UNI EN ISO 1461 standard; minimum guaranteed thickness of 55 microns;
• Inner tube diameter: 48×3,00 mm;
• Outer tube diameter: 60×2,50 mm.

Available upon request:

• Personalized label with the client’s logo, including information about load capacity and maximum extension.

Properties of the props:

• Guaranteed tension 38,00 kN;
• Internal pipe diameter 48×3,00 mm;
• Pipe diameter 60×2,50 mm.

In H-type models, achieving vertical alignment is possible thanks to two spheroidal cast iron bushings that either increase or decrease the extension. This model is produced in two variants: H1 and H2.

H-type vertical props distinguish themselves from other classes by their method of vertical alignment adjustment. This is achieved using two bushings that increase or decrease the extension of the prop.

GBM manufactures two types of H supports: H1 (with a smaller diameter) and H2 (with a larger diameter). Both versions feature:

• Adjustable length from 1.80 to 5.40 meters, depending on the support model, with a 10 cm increment, using the adjustment of two steel bushings;
• Guaranteed tension of 38.00 kN, regardless of the applied extension;
• Anti-shearing system: increased length of the inner tube compared to the outer tube ensures at least a 10 cm difference between the two tubes during the closing phase, preventing accidents;
• Plates mounted on hinges at both ends ensure better adherence, allowing the prop to be fastened and assembled at various angles;
• Tube protection: hot-dip galvanizing according to UNI EN ISO 1461; minimum guaranteed thickness of 55 microns;
• Inner tube diameter 63×2.60 mm;
• Outer tube diameter 76×2.60 mm.
