9.6 9.6 SERVICING THE TRAM BRAKE SYSTEM SERVICING THE TRAM BRAKE SYSTEM
The TRAM Brake System functions in one of two positions – locked or released. The locked position is the default
position of the brake system and locks the TRAM Device in its position on the TRAM Rail. The lock mechanism
consists of four brake pads mounted on two horizontally opposing brake shoes. The brake shoes are normally
closed against the TRAM Rail, with the closing force provided by a mechanical coil spring.
The Brake System is moved into its released position by activating the Brake Lever. The Brake Lever is mounted at
a convenient position on the TRAM Arm and is activated by clasping the lever and pulling it up against the TRAM
Arm. The lever action pulls a mechanical cable which runs from the Brake Lever down through the TRAM Arm to
the Brake Mechanism. The end of the mechanical brake cable is attached to two pivoting arms and as the brake
cable retracts the arms pivot to extend the mechanical coil spring and open the brake shoes, thus releasing the
closing force of the brake pads against the TRAM Rail. Figure 9.6.2 shows an exploded assembly view of
components referenced in the procedures in this Chapter.
Your TRAM is fitted with either a Type I or a Type II Brake System. To determine which Brake System your TRAM
is fitted with refer to the illustrations and explanations below.
