2-inch and 3.5-inch semi-trailer king pin frequently referred to as the “pivot point" between the semi-trailer and truck.

King pin is produced in 2 and 3.5 inch sizes in compliance with SAE/DIN standards. The 2-inch size D value is between 152-190 kN and the 3.5 size D value is up to 260 kN. King pin dimension and capacity values are preferred according to prime mover 5th wheel size and its load capacity.

King pins consist of 2 parts: king pin head and mounting bracket. King mounting bracket and king pin head is connected with 8 pcs bolt connection. With the bolt-on mounting bracket structure, 2 inch and 3 inch king pin heads can be easily replaced. With interchangeable 2”-3,5” king pin head structure, the semi-trailer will be easily usable with any prime mover.

* Please request information for higher kN

5 -   Assure the sufficient mechanical resistance of the trailer coupling plate

6 -   The welding must make at once

MAINTENANCE

1 -   The greasing of the pin as the bolt torque and usage diameter must be controlled at least every 15 days

2 -   Use grease with quality least EP 2
