Screw-on track drainage boxes

Channel off all dirt

In the course of time, dirt, sand, leaves and lots of other things gather in grooved rails and reduce the effective rail depth thus impairing the safe track guidance of rail vehicles. By mounting HANNING & KAHL track drainage boxes, all contamination and rainwater can be quickly drained off from the grooved rails into drainage channels.

On account of its large drainage opening, the groove can be flushed quickly and in a practical manner. Contamination and blockages can be easily removed through the drainage pipe accessible through the lid which is equipped with bayonet locking. The drainages boxes can be screwed to the rail with 2 screws.

Technical data:

• Compact cast steel housing with protective coating for all types of grooved rail profiles
• Mechanical connection to the web of the rail through track rod screw M22 in line with VÖV 3.570.3 Bl.2
• Clearance of the fastening screws is identical to the screw clearance when assembling the track rod screw
• Can be crossed over with up to
• 12 t axle load
• Cast lid with bayonet locking and chain protection
• Opening for cleaning lance in the lid, i.e. cleaning also possible without screwing off the lid
• External dimensions of the housing the size of a paving stone
• 20°- Flow-off gradient in the interior favours water drainage i.e. reduces the degree of contamination
• Easy assembly
• Fastened to the web of the grooved rail instead of a track rod without additional holes. Holes as for track rods
• Large diameter of the connection (88 mm, inner)
• Can be screwed on with commercially available screws and nuts, as in the case of track rods
