The overall width typically ranges from 2400 to 2600 mm, matching the terminal tractor's front axle track width. However, this is a reference range; the exact width must be confirmed for the specific tractor model.
The bumper is commonly made of high-strength low-alloy steel grade Q345B, as specified in GB/T 1591. This grade provides a minimum yield strength of 345 MPa. Always verify the material grade with the supplier for your application.
The bumper is typically mounted using four M16 bolts of grade 8.8, per ISO 4014. The mounting bolt pattern is part of the design and must be checked against the tractor's frame to ensure proper fit and load distribution.
The surface treatment usually consists of an epoxy primer followed by a polyurethane topcoat, with a dry film thickness of 80 to 120 μm per ISO 19840. This provides corrosion resistance for outdoor port and terminal environments.
