Description

Embodiments described herein relate generally to a fire-fighting locomotive.

  Locomotives for steelworks run by pulling a dedicated freight car (commonly called a bucket car) for transporting coke between a coke oven and coke fire extinguishing equipment that are installed in order to generate coke for iron making. The locomotive has a special shape suitable for digestion work and is called a fire extinguishing locomotive. The fire-fighting locomotive has a two-story structure, the first floor is a machine room where equipment for driving the locomotive is installed, and the second floor is a driver's room where operating equipment for operating the locomotive by the driver is installed. It has become. Therefore, when the driver's seat moves to the driver's cab on the second floor, the stairs installed next to the driver's cab are used. In order to protect the driver from the heat of the coke oven, the driver's cabin on the second floor is shifted from the machine room on the first floor and protrudes to one side. Further, in recent years, since it is desired to increase the output capacity of the locomotive, the driving device has been increased in size. Along with the increase in the size of the drive device, the drive device is also placed in the cab because the wiring becomes complicated when placed in the machine room on the first floor. For this reason, the driver's cab requires a space for installing the driving device and the operating device, and has been enlarged. Since the cab larger than the machine room is installed in the upper part, the balance of the vehicle body has deteriorated.

In order to cope with such vehicle unbalance, the fire-fighting locomotive has a dead load that is a weight for adjusting the balance in consideration of the arrangement of equipment in the machine room, the arrangement of equipment in the cab, and the position of the cab. It was installed.
