Crane Rail In the process of running the crane, we must first determine the normal trailer track, where these things for everyone to explain:

  1, the track joints to retain the gap, so that thermal expansion and contraction, the general gap 1-8mm.

  2, the orbital joints at the horizontal displacement and high and low roughness error shall not be greater than 1mm.

  3, two parallel tracks, the level of the level of error, the pillar shall not exceed 10mm, in other places shall not exceed 5mm.

  4, the same side of the track, the height between the two pillars and adjacent columns between the standard error, shall not exceed B / 1500 (B for the distance between the columns, in mm), and up to no more than 10mm.

  5, orbital span, track center and beam center, the track is not a linear error, etc., shall not exceed the relevant provisions.

  6, in order to prevent the electrical failure of the crane caused by equipment, the track should be grounded, the two corridor connection gap at the application of splints connected into one, grounding conductor should comply with the relevant provisions.

  Crane Rail Crane in the process of running the wheel and the track common fault for the wheel's gnawing and the car is not tall, slippery. Which caused the reasons for gnawing is multifaceted, and the form of gnawing is diverse. Grate the light of the impact of the life of the crane, heavy cases will cause serious casualties, so special equipment management staff for the gnawing to cause enough attention. The main reason for the gnawing is the installation does not meet the requirements of the error, uneven friction and cart parts in the drive wear is too large, the key to connect the gap caused by excessive braking is not synchronized.

  Crane Rail Therefore, the units of special equipment in the installation and maintenance of cranes must find a qualified unit to install and repair, so as to ensure the safety of equipment and operating life; at the same time special equipment management staff to strengthen the usual inspection and management, to avoid the crane occurred Road mechanical failure, in the inspection process to carefully and carefully find the reasons for gnawing, and take appropriate measures. Trolley wheel is not equal to the crane is running very insecure factors, the car ranging from the car in the operation of a wheel in the air or too small may cause the car body vibration. The main reason is that the installation error does not meet the requirements and the design of the car itself is not uniform weight, so the car is not equal to the full analysis of the fault, the car ranging from the car, High problem solving.
