A power tool includes a handle assembly, a power supply, and a temperature control module; where the handle assembly includes a left grip and a right grip, where a first end of the left grip is coupled to a body of the power tool, a second end of the left grip is coupled to a first end of the right grip, and a second end of the right grip is coupled to the body of the power tool; the temperature control module is coupled to the handle assembly and the power supply separately; and the power supply is configured to power the temperature control module so that the temperature control module is configured to heat the handle assembly.

A snow removal device includes: a brush rotary shaft that is mounted on a vehicle body traveling along a track and in front of a running wheel of the vehicle body and that is rotated in a direction opposite to the rotation direction of the running wheel; a travel brush part that protrudes radially outward from an outer circumferential surface of the brush rotary shaft and comes into contact with a runway of the track with which the running wheel is in contact; and a brush pressing part that presses the travel brush part toward the runway. The travel brush part is provided in a spiral region formed on the outer circumferential surface of the brush rotary shaft in a spiral manner extending toward an axis direction in which the axis extends as going toward a circumferential direction of the brush rotary shaft.

A snow removal brush includes a brush rotary shaft that is disposed on each of opposite lateral surfaces of a vehicle body traveling along a track and in a vehicle width direction of the vehicle body and is supported by the vehicle body to be rotatable about an axis extending in a direction intersecting a track surface of the track, and a brush part that protrudes from an outer circumferential surface of the brush rotary shaft to a radial outer side. The brush part is formed to come into contact with trolley wires provided for the track and supplying electricity to the vehicle body.

The present invention is a grinder head for attaching to a track cleaner. The present invention also includes the grinder head attached to a track cleaner. Preferably, the present invention will continuously grind and load hard frozen minerals like taconite or ice. In addition, the present invention preferably aids in removal of hard-to-handle material such as wet, sticky bentonite from tracks which can be difficult in the summer months. The grinder head attachment will preferably allow operators to use a track cleaner to remove materials, preferably in one pass, during the colder months when the bentonite is frozen and much easier to handle. Preferably, the present invention will also be able to remove concrete or asphalt surfaces at road crossings.
