When the tunnel mucking machine excavates in the roadway, there is a phenomenon that the tire cannot be reversed backward, which brings great inconvenience to the user. Tunnel mucking machine tires can not back up the reasons for what, how to solve and prevent it as a tunnel mucking machine after-sales service personnel to be clear. The following are some of the reasons why we can't back up the tires and how to solve them, and put forward some things that the tunnel mucking machine driver should pay attention to during normal work.
The tunnel mucking machine uses 650-10 small-scale engineering tires, which need to be frequently retracted during the work process, and requires good starting and braking performance. This type of tire uses ultra-high wear-resistant tread rubber layer. When the tires and the chassis are braked, the wheelbase and the torque are increased, and the brake drum is decelerated and twisted.
Although the torque of the brake drum is small, the torque of the tunnel mucking machine is greatly increased after deceleration, especially the second-stage deceleration, so there is a high requirement for the rigidity and strength of the gear of the hub. The tunnel mucking machine needs to be retracted, which makes the gears of the hub also move frequently, so the wear of the hub gear is also relatively large. Therefore, the gears of the hub need to be lubricated and cooled, so the good quality gear oil is extended. The basic guarantee of the gear life of the hub. We need to replace the dirty gear oil in time after using it for a while.
