Introduction

After the introduction of the KLP® Switch sleepers

Lankhorst has also developed the KLP® Bridge sleeper.

This sleeper is based on the same technology as the

switch sleeper but can be produced in different heights.

The last few millimeters can be milled of.

In this way KLP® bridge sleepers can be supplied with

millimeter accuracy. Lankhorst can pre-install the

fastening system and mark the sleepers with a unique

number to ensure a fast installation.

KLP® Bridge sleepers are very suitable for the

replacement of wooden sleepers on (steel)

bridges. Since 2010 KLP® Bridge sleepers are

installed on several locations in The Netherlands

on steel bridges. These bridges are being

monitored closely and are performing well.

After the first installation on a bridge in 2010,

Movares, a Dutch consultancy and engineering

company, has performed sound measurements.

The sound was measured before and after

installation of the plastic sleepers. Movares

concludes that the application of plastic sleepers

has reduced the sound with 3-5 dB compared to

wooden sleepers.

Lankhorst Mouldings

Lankhorst Mouldings can already look back at a

successful and versatile history of over 30 years, but

we tend to look at the future as the future always

brings new opportunities, new ideas and most

importantly new solutions. Since Lankhorst produced

its first plastic post according to the intrusion process in

1977, many innovations have come to maturity.

Today Lankhorst has their own Research and

Development department capable of designing,

calculating and testing products. Lankhorst now serves

a variety of markets with large plastic products molded

from either recycled plastic s or new materials. For an

overview of markets and product portfolio we invite
