The invention provides an engineering mechanical vehicle body which relates to the structural field of various engineering mechanical vehicle bodies, such as an excavator body, a loader body, and the like. The engineering mechanical vehicle body comprises a vehicle body inner frame, a vehicle body outer frame and glass, wherein the vehicle body outer frame is arranged outside the vehicle body outer frame, the glass is arranged in the vehicle body outer frame, a polyurethane bonding agent is arranged between the vehicle body outer frame and the glass, a vibration isolation cushion is also arranged between the vehicle body outer frame and the glass, and the vibration isolation cushion is arranged around the polyurethane bonding agent. The invention has the advantages of reducing the bonding operation difficulty of the glass and the vehicle body, effectively controlling the filling height and the area of the polyurethane bonding agent, ensuring bonding intensity and firmness, effectively controlling bonding gaps, further increasing appearance quality and reducing the vibration frequency of the glass when the glass works.
