Abstract

PROBLEM TO BE SOLVED: To provide a heating apparatus for a forklift to efficiently using oil temperature of return oil and to save consumption of electric energy of a battery. SOLUTION: This is an apparatus constituted by providing a changeover valve 12 in pressure oil return pipings of a hydraulic piping of a forklift, arranging one of the return pipings in a car body, arranging the other return piping on a side board and connecting it to an oil tank.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater for a forklift which effectively utilizes the oil temperature of return oil and saves the consumption of electric power of a battery.

[0002]

2. Description of the Related Art Conventionally, a heater mat connected to a battery is mounted on a sideboard or an electrothermal fan is mounted in a cabin room.

[0003]

Conventionally, as described above, since the batteries are all powered as described above, there is a problem that the operating rate is lowered due to the limitation of the capacity, or the deterioration of the oil is accelerated by the high temperature. was there.

[0004]

According to the present invention, a switching valve is provided in a pressure oil return pipe of a hydraulic pipe of a forklift, one of the return pipes is arranged inside a vehicle body, and the other is arranged on a sideboard to form an oil tank. To solve the above-mentioned problems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. 1. Reference numeral 1 is a forklift, 2 is a vehicle body of the forklift, 3 is a pair of masts standing upright in front of the vehicle body, 4 is the mast. With a lift cylinder arranged at the rear of the lift cylinder 3, a fork (not shown) rises due to expansion and contraction of the rod of the lift cylinder 4.

Reference numeral 7 is an operation valve provided on the vehicle body 2, 8 is a pump,
Reference numeral 9 is a hydraulic motor for rotationally driving the pump 8, 10 is an oil tank for storing oil, 11 is a heat radiating portion formed by a return pipe, and 12 is a case where oil is flowed to the heat radiating portion 11 and a case is not flowed. It consists of a switching valve divided into two parts, and they are connected by a pipe.

In the summer, the switching valve 12 is switched so that oil does not flow to the heat radiating portion 11 and oil flows to the heat radiating portion 11 in winter, and the high temperature heat is radiated to heat. I'm using it.

[0008]

As described above, the present invention has an effect that it can be used for heating only by switching the switching valve in winter and that the cargo capacity can be prevented from lowering and long-term cargo handling work can be performed.
