Description

Cab guard and excavator with cab guard installed

technical field

The utility model relates to a driver's cab, in particular to a driver's cab protective device and an excavator equipped with the driver's cab protective device.

Background technique

Excavator is a kind of construction machinery, which is widely used in construction, road, mine, port and other engineering fields. The main function of the excavator is to carry out excavation work. The vast majority of today's excavators are hydraulic excavators. Hydraulic excavators generally include working devices, slewing devices and traveling devices. Among them, the working device is a device that directly completes the excavation task. The walking device is used to drive the whole machine to walk and move the position. The slewing device is located between the traveling device and the working device, and is used to drive the working device to rotate on the horizontal plane. The cab is usually located above the slewing gear and behind the working gear. When the excavator is working, the driver sits in the cab and manipulates the working device to work. The cab of the existing excavator lacks protective devices. When the excavator is operating in a mine or quarry where there is a risk of falling rocks, the cab is likely to be impacted by the falling rocks in front or above, so that the machinery in the cab is damaged or the Driver causing personal injury.
