• Height (H): 2.38 m
• Width (B): 2.36 m
• Shoring length between trench ends (L V): 7.00 m
• Number of box profiles: 18
• Upper beam thickness (UB thickness): 0.30 m
• Permissible beam load: 80 t
• Machine weight without accessories: 21,100 kg

2. Pressbox Pipe Clearance and Lower Beams

Details related to pipe clearance and lower beam specifications include:

• Length (L): 7.19 m
• Height (H): 1.07 m
• Lower beam thickness (t UG): 0.27 m
• Lower beam length clearance (L C): 5.75 m
• Number of lower beams: 2
• Permissible beam load: 218 t
• Weight without accessories: 7,700 kg

3. Machine Lower Beam Specifications

Two sizes of machine lower beams are specified with the following parameters:

• Dimensions: Length 7.30 m and 9.30 m, Height 0.36 m, Thickness 0.22 m
• Quantity: 4 pieces each
• Permissible bending moment: 185 kNm
• Weight without accessories: 930 kg (7.30 m beam), 1180 kg (9.30 m beam)

4. Side Slide Rail Details

Side slide rails are characterized by their dimensions, number of box profiles per side, permissible bending moments, and weights. Key data:

• Lengths: 7.30 m and 9.30 m
• Width: 0.79 m
• Thickness: 0.10 m
• Number of box profiles per side: varies (1 or 7 depending on position)
• Permissible bending moment: 384 kNm/m
• Weights vary by position and length, e.g., 1430 kg (right-nut at 7.30 m), 1760 kg (right-nut at 9.30 m)
• Positions include right-nut, left-spring, and center

5. Box Profiles and Spacing

The widths and distances between profiles and beams are specified as follows:

• Width between profiles (bC): minimum 1.52 m, maximum 4.70 m
• Width between upper beams (b OG): 0.92 m to 4.10 m
• Width between lower beams (b UG): 0.98 m to 4.16 m
• Length of distance piece: 0.46 m to 3.64 m
• Trench outside width: 1.73 m to 4.91 m
• Machine outside width: 2.84 m to 6.02 m

Critical Parameters and Recommendations

• Ensure permissible beam loads and bending moments are not exceeded to maintain structural integrity.
• Machine weights are provided without accessories; additional weight should be considered in planning.
• Dimensions and clearances must be matched to trench and utility requirements for safe shoring.
• Side slide rails have specific positions and load capacities; proper installation is essential.

This summary captures the essential technical specifications and parameters for the Hydraulic Pressbox Series 800 used in shoring around utilities, focusing on dimensions, load capacities, and component details.
