HLY-INS-04: Gantry Crane Track Foundation Leveling & Festoon Cable Installation

1. Crane Rail Foundation & Alignment Tolerances

Heavy-duty P43 or P50 crane rails fastened upon continuous concrete grade beams.

Span Gauge Tolerance: Actual track gauge vs nominal span $S$ deviation must be within $\pm$3.0 mm.

Rail Top Leveling: Longitudinal gradient must not exceed 1/1000; transverse cross-elevation difference between left and right rails must be $\le$ 5.0 mm.

Expansion Gaps: Leave 15–20 mm gaps at rail joints with fishplates or thermite-weld flush.

2. Wind Anchors & Safety Rail Clamps

Both track ends require spring or polyurethane end-stops capable of absorbing kinetic impact.

Install ground mooring anchor plates and automatic hydraulic spring-loaded fail-safe rail clamps.

3. Seamless Enclosed Busbar Installation

Mount busbar brackets at 1.5–2.0 m intervals ensuring parallel run with the rail.

Maintain carbon brush contact shoe spring force at 15–20 N to eliminate electrical arcing during travel.
