Features of the Hakone Tozan Cable Car

When the Cable Cars are Passing Each Other, They Pass on the Same Side

The point where the cable cars going opposite directions cross paths (called the railway switch) is different from most railways. If you look at figure one, you can see that the outer track does not have a gap, whereas the inner one does in order to let the rope pass through. In order to accommodate this, the wheels of the cable car are shaped quite differently from regular trains.

The wheels, which you can see in figure 2, come in a set of one groove wheel and one flangeless wheel. Unlike regular trains where the wheels are connected with an axle, each of these wheels is independent and not connected to a suspension system. What’s more, the leading pulley block that supports the wire rope between the rails is in place. The groove wheel is on the right side of the 01 train (ケ11-ケ21), when on the way towards Sounzan Station, and the flangeless wheel is on the left. The flangeless wheel is on the right side of the 02 train (ケ12-ケ22), when on the way towards Sounzan Station, and the groove wheel on the left. Both the 01 train (ケ11-ケ21) and the 02 train (ケ12-ケ22), when heading towards Sounzan Station, do not have a gap on the outside rail where the groove wheel is. When heading towards Sounzan Station, 01 runs on the right and 02 is runs on the left. In order for the flangeless wheel to go over the gap, the area is flat.

Cable Car Brake System

There are two types of brakes on the Cable Car, the automatic brake and the emergency brake. The automatic brake is a Gieserei-Bern Brake. Depending on the rotational force, this brake allows the brake caliper to expand and cause the brakeshoe to hit the top of the rail (figure 3). The emergency brake uses oil to move the wedge of the brake caliper into the rail, then operates the same way the automatic brake does.

Sounzan Station's Hoisting Machines

Sounzan Station is at the top of the Cable Car Ropeway. This is where the operation components, such as the hoisting machine, are set up. The hoisting machine (figure 4) has a pulley, speed controller, motor, control unit and brake. The control unit uses the motor to control the wheel rotations, and the speed controller reduces the speed (3.2m every second), and the pulley pulls the train directly. The pulley’s wire rope winds up, and the train moves up or down depending on the direction the rope is wound.
