DAKO-CZ will deliver hydraulic brake units, including controls, for a total of 80 modernized trams to Göteborg, Sweden, in the upcoming years. The manufacturer of brake systems and components for rail vehicles from Třemošnice in East Bohemia will produce them in the upcoming years for the sets that will be modernized by Škoda Group at its Škoda Ekova plant in Ostrava. The price of the contract for the delivery of a completely new hydraulic brake system reaches almost the amount of CZK 110 mil.
The original brake system of the M31 tram was a combination of a pneumatic brake system on a motorized chassis and a hydraulic brake system on a conventional chassis. The basic purpose of the modernization was the condition to deliver a complete hydraulic brake system for all chassis types. The M31 modernized trams consist of three chassis types, two motorized ones and a conventional one. The motorized chassis will be equipped with two-circuit passive braking units, and the conventional chassis with an active braking system. The M21 sets were produced in 1984-1992 as two-link ones, in 1998-2002 the first modernization to three-link trams with the designation M31 took place.
We are delighted to be involved in this contract and to contribute to improving the operational safety of the modernized trams in Göteborg. The contract obtained follows on from the successful cooperation with Škoda Ekova within the reconstruction of the braking system on trams for Tallinn, Estonia. In Göteborg, this modified braking system will be used on the conventional chassis, and we will develop a new braking system for the motorized chassis, due to the high relative movements of the brake disc to the brake unit. The contract is very important for us; it is the second largest project in the field of hydraulic brake system deliveries, and the deliveries will last until 2027.
As part of the contract, DAKO-CZ will specifically deliver the iRB 03.3 control system, the newly developed M31 brake units, brake discs and combined emergency braking units, emergency brake units with a safety circuit, JA 52 active brake units, active brake units and brake discs.
