About the cab, things you have to know......

Throughout the development and application of the domestic Komatsu excavator cab in recent years, it is not uncommon to find the problem of the low efficiency of the whole machine due to the improper design of the Komatsu cab accessories. It can be seen that the excavator cab is reasonably and scientifically carried out. The design and layout of the various components is particularly critical. In response to this problem, our company specially combines its current state of the art and technology, and in accordance with the relevant requirements of ergonomics, redesigned and deployed the positions of the existing components inside the cab of the excavator, and the specific improvement measures. See below for details.

Komatsu excavator cab manufacturer refers to GB000-88 (Chinese adult human body size) to produce a 1:5 flat human body template, in accordance with JB3683-84 "Construction machinery handling comfort zone and reach" Centered on the chair, determine the position of the joystick, throttle, and monitor buttons on the instrument panel. Draw the floor plan of the excavator cab. Within the allowable range of the human body size and comfort zone, the position of the seat in the cab should be as far as possible. The size of the plane on the seat cushion should be larger than the floor, which is beneficial to increase. The view is large and the driver's operation on the pedal is less laborious. The basic situation of the specific cab layout is not detailed.
On this basis, the installation of refrigeration and air conditioning, limited by the production volume, if the custom air conditioning for excavators, will inevitably increase costs. Therefore, we chose the instrument panel air conditioner for the car, which was placed behind the driver's seat with the mounting bracket and the original heater. According to the calculation of the ambient temperature, the heat transfer coefficient of the siding and the glass, and the cab volume, the cooling capacity required for the air conditioner should be greater than 3500 kcal/h, and the power consumption of the entire air conditioning system is less than 4 kW. The air conditioning system installed in the excavator cab is tested. It can fully meet the requirements of domestic users.
The improved excavator cab was installed on the WY22LC excavator produced by the Tow Company and tested by the National Engineering Machinery Quality Supervision and Inspection Center. The driver's ear noise was 75.8dB(A). This value is close to the level of the foreign excavator cab, and is in a leading position in China. In addition, the lower viewing capacity is increased by two and a half compared with the original cab, and the driver consistently reflects that the operation is lighter, more comfortable, and the work efficiency has also been significantly improved.
 
The above is only a brief view and suggestion of the company's years of design and development experience, the rational design and deployment methods of modern Komatsu cab accessories. If there are any inaccuracies, we hope that the industry peers and experts will correct me. Make an humbly correction to further advance the R&D design quality level of Komatsu's cab.
