Problems solved by technology

When such a cab is deformed due to direct impact, it will of course bring great danger to the operators who operate in the cab.
In addition, due to the deformation of such a cab, the door cannot be opened, and there is a danger that the operator cannot escape from the car.

Abstract

PROBLEM TO BE SOLVED: To provide a construction machine securing the safety of an operator in an operator's cabin by protecting the operator's cabin even if the construction machine turned over. SOLUTION: In this construction machine such as a hydraulic shovel having a swing frame 1 and the operator's cab installed on the swing frame 1, a protective structure 3 for the operator's cab for preventing the operator's cab 2 from receiving a direct impact when the construction machine is turned over is installed on the upper surface part 2a of the operator's cabin 2. The rear end part of the protective structure 3 for the operator's cabin is supported by a column 4a installed on the swing frame 1. A support body 5 supporting the front end part of the protective structure 3 for the operator's cab when the protective structure 3 for the operator's cab receives impact by the overturning of the construction machine is installed above the upper end part of a front pillar 2b between the upper surface part 2a of the operator's cabin 2 and the protective structure 3 for the operator's seat.

Description

technical field [0001] The present invention relates to a self-propelled construction machine such as a hydraulic excavator having a rotating frame and a cab provided on the rotating frame. Background technique [0002] A self-propelled construction machine such as a hydraulic excavator is composed of a lower traveling body and an upper rotating body. The lower traveling body uses crawler belts for the self-propelled construction machine to travel. The upper rotating body is rotatably provided on the lower traveling body. The upper rotating body is provided with devices such as a driver's cab, a mechanical room, and a counterweight on the rotating frame as its chassis. A working device (front end) is usually provided at the front end of the rotating frame. The working device has a beam that can tilt relative to the rotating frame, a forearm that can swing relative to the beam, and additional devices such as a bucket that can swing relative to the forearm to perform various o...
