What is the matter of gear going freely for the excavator steel grab in the process of operation ? Is it bad quality or improper operation? How exactly does it happen ?
No.1:Gear in the process of processing and production heat treatment is hard, although the hardness is high and the wear resistance is good, but at the same time, there will be a problem of the weakness of the brittleness toughness, this requires engineer to solve it in the exploring experience for many years , each manufacturer has its own technology to control the gear heat treatment process, so that hardness and toughness are better at the same time.
No.2:For one excavator steel grab ,after grabbing heavy objects, do not do rotating action when lifting in the air, it is recommended that after grabbing heavy objects, be sure to be perpendicular to the ground and then do rotating action, tilt rotation hydraulic motor and pinion subjected to a large radial force, if long-term those work, gear and motor will break teeth and shaft due to the action of radial force, here it is strongly recommended that you try to rotate vertically, Occasional, but not frequent, oblique rotations are okay.
It will inevitably appear mechanical strength fatigue for one Mechanical equipment after long-term use, so a careful driver is more important than anything, if the excavator steel grab is doing the rotating action, it appears a stuck phenomenon ,then at that time ,it is recommended that you immediately stop to check, eliminate circuit faults, timely check the pinion wear situation, if the equipment works for a year ,here is recommended to regularly replace the pinion, less investment and high return, do not pennilwise and pinion pound!
