Grab maintenance: Grab use in common fault is the abrasive wear, according to data analysis can be found in the form of failure in grab grab mine pneumatic plant, due to the loss of tip wear pumping performance of about 40% of supply Pneumatic grab mine, due to the bucket edge wear body lose about 30% of the work performance of pneumatic grab mine, and because the pulley wear and damage to other parts of the loss of about 30% of operating performance. Grab the bucket body and host two major components. Host is a crawler cranes, crawler cranes single rope grab the rope from gravity should not be less than 120kN; hydraulic crawler crane grab hydraulic system should be configured. Many grab itself with inclinometer and Straightening device can sense and correct bucket body through sensors and hydraulic system skewed.
