Design
A welded box structure is used, which avoids the cracks and leaks of oil caused by casting defects.
Process
For welding, a special welding machine is used, a medium -frequency hardening machine for total single heating and spraying to ensure the effectiveness of the heat treatment of the guide wheel and make the wheel body more durable and durable.
Improving the design
(This item refers only to the original details 5A) The design integrated with the tension mechanism prevents the machine from the rails due to the slipping of the guide wheel, reduces the abnormal wear of the caterpillar chain and increases wear resistance.
