Description

Technical Field [0001] The present invention relates to a heating grip handle for heavy equipment,

The present invention relates to a heating grip handle device for a heavy equipment, and more particularly, to a heating grip handle device for a heavy equipment which can smoothly operate a heavy equipment even in a winter season with a built-in heating wire.

Generally, various kinds of heavy equipment are used for the construction work in construction site or civil engineering work site. These heavy equipment include excavators, bulldozers, cranes, and forklifts.

Among them, Excavator performs various works according to the attached attachment such as excavation work for digging the earth in civil engineering, construction, construction site, loading work for transporting soil, shredding work for dismantling the building, suspension work for arranging the ground So it is used for various purposes in construction or civil engineering works.

Such an excavator generally comprises a traveling body that serves as a moving part of the equipment, and an upper swivel body and a working device that are mounted on the traveling body and rotate 360 degrees. The crawler excavator is divided into crawler crawler excavator and tire type excavator according to the driving method of the traveling body. In this case, since the crawler excavator is more stable and work productivity than the wheel excavator, , The wheel excavator is less stable than the crawler excavator due to the tire supporting system. However, it is possible to travel on the road so that it can move the workplace without the trailer, It is mainly used in demanding work sites.

In addition, excavators can be fitted with appropriate attachments as described above, depending on the state of the earth and rock, the type of work, and the application. Such attachments include buckets for general excavation and soil handling, Breakers for crushing of buildings, and crushers used for dismantling and crushing buildings.

The attachment is attached to an end of a boom frame including a plurality of rods extending from a turning body and pivoted by a hydraulic cylinder, and can perform work such as crushing or crushing a workpiece through operation of the swivel body and the boom frame.

The operation of the swing body and the boom frame is controlled by a driver sitting on the driver's seat. A lever-type handle device for controlling the driving of the swing frame and the boom frame is provided on both sides of the driver's seat. Thereby controlling the driving of the boom frame and the swivel body.

In the case of a large excavator, the driver's seat is limited to a separate space divided from the outside, while in the case of a small excavator, the driver's seat is usually exposed to the outside. Therefore, in the cold season when the temperature is low, it is influenced by the wind. Especially, the hand holding the handle is frozen and difficult to operate. Particularly, in the case of a handle, a thick glove which can prevent a chill when working with a long length has a problem that it is difficult to perform a sophisticated work by dulling the sense of the hand.
