NEW INSPECTION VEHICLE

An Italian company has supplied a bridge inspection vehicle that can work on both

road and rail bridges. The AB 6.5/S Combi model has been sold to a Malaysian construc-

tion company.

It will be used to inspect bridges of Malayan Railway (KTM) under a bridge

strengthening and replacement and track realignment program. It is also available for con-

ventional road bridge work.

The machine is mounted on a Volvo truck chassis equipped with special meter-

gauge railway wheels. The platform can be positioned for work both under and over the

bridge. Performances for horizontal and vertical work under a bridge are similar for both

road and rail bridges.

The vehicle is equipped with an ergonomic work platform from which operators can

control all functions.

HERE ARE TONS OF REASONS TO CHOOSE STEEL SLEEPERS

It’s clear that steel sleepers offer major advantages over their concrete or timber

counterparts, and the benefits continue down the line. Steel sleepers are much lighter and

therefore easier and more economical to handle than concrete ones. They also ‘nest’ when

stacked, providing dramatic reductions in storage area requirements and reduced transport

costs – typically a trailer load is 330 steel sleepers compared to just 85 concrete units.

Renewal costs for track laid on steel are much less than for concrete - up to a 29%

reduction in costs has been shown in recent reviews.

When relaying with steel sleepers typical new ballast requirement is 0.5 tones/m as

opposed to 5 to 6 tones/m for concrete.

Possession periods are far more predictable.

Steel sleepers can offer faster laying speeds than concrete installations, giving dra-

matically increased productivity.

Maintenance costs are much lower than those with wood or concrete.
