The following requirements must be met in order for the crane to be installed:

─     The tolerances of the crane track must correspond to the following criteria.

The tolerances specified correspond to DIN EN 1090 for Class 2 crane classifications.

Site of a crane track in floor plan B:

View from above.

─     Deviation B across the entire length of the crane track: B = ± 5 mm.

─     Within 2 m, the deviation may not be greater than B = ± 1 mm.

Height of crane track C:

View from the side.

─     Deviation C across the entire length of the crane track: C = ± 10 mm.

─     Deviation C across the entire length of the crane track must not be greater than C = ± crane track length L / 1000.

─     Within 2 m, the deviation may also not be greater than C = ± 2 mm.

Height of the crane tracks in relation to each other E:

Cross-sectional view.

─     Where S ≤ 10 m, the following applies: maximum difference in height E = ± 10 mm.

─     Where S > 10 m the following applies: difference in height of the crane tracks E (in mm) must not be greater than E = ± span S / 1000.

Deviation from span A:

View from above.

─     Where S ≤ 16 m, then A = ± 5 mm applies.

─     Where S > 16 m, then A = ± [5 + 0.25 (S-16] mm applies.

With S in m and the result in mm.

Position of the end stoppers in relation to each other F:

View from above.

─     The offset of end stoppers F must not be greater than F = ± span S / 1000.

─     Maximum offset F = ± 10 mm.

Incline of the crane track from the horizontal vertex G:

Cross-sectional view.

─     Deviation G = 1% of the width K.

Incline of the crane tracks to each other:

View from the side (perspectively)

─     Incline of the crane tracks to each other: Incline between A1 and B1 (wheel base) – incline between A2 and B2 (without algebraic sign) must not be greater than L (distance between A1 and B1) / 1000.

─     The supplied overhead travelling crane must correspond to the overhead travelling crane that was provided for in the layout plan.
