due to the loss of tip wear and pumping performance of about 40 %

Grab common use in fault yes yes abrasive wear , according to the related data analysis can be found in the form of grab failure , due to the loss of tip wear and pumping performance of about 40 %, due to bucket edge wear and loss of body work performance about 30 %, while other parts of the pulley wear and damage and lose about 30% of the performance of the work . Thus, grab the pin and sleeve improve abrasion resistance, increase the bucket body edge abrasion resistance, both of which are an important way to improve the life of the grab . Factors affecting material wear external factors and internal factors . External factors include the load , sliding speed , hardness, and geometry of the abrasive and other factors. Internal factors include the chemical composition , carbide type , microstructure , etc. External factors is self-evident , there is not going to describe . In order to improve the life of grab to grab all wear parts for different situations , use of different wear-resistant materials , and supplemented by a different process , thus greatly improving the life of the grab .Grab frequently used because , in addition to the driver's operation of ship unloader is limited, grab the failure rate is very high, so the daily point inspection process to Electric pallet jack these parts of the examination , but also to make these parts of the maintenance work , try to grab the life of the short length , and increase productivity. To better manage grab, protect production to ensure safety, according to grab involving the use, maintenance , repair personnel composition, scope of work and work processes , especially the development of the following terms:
a. duty long day should be promptly arrange grab refueling ; every Monday , Thursday arrange grab some oil on the bolster ; postponed if there are special circumstances allows a maximum of one day , and the situation recorded in the duty log , the shift supervisor on duty the next day alternative arrangements refueling.
b. Drivers refueling should meet standards to ensure adequate lubrication ; such as refueling, plus does not feed should be documented and reported to the point of inspection personnel or supervisor technician. Do a good job running the log requires refueling every case record.
c. Drivers should take the initiative to accept grab refueling refueling inspectors opinion.
d. driver operated , should avoid collision grab cabin and other accidents , to eliminate errors due to methods of operation as a result of similar incidents .
e. Drivers should be observed in real time during the operation grab usage , if found chains , quick connectors , which are signs of wear should be timely refueling ; grab other fault if found or suspected faults should stop to check and report timely , while running log make a record.
f. point inspection personnel should grapple check work done on the timeliness, accuracy, validity, in order to strengthen grab replacement, repair planning .
g. point inspection check out the grab failure or suspected failure should be promptly reported to the competent grab and records management overhaul at the point on the table .
h. point inspection personnel should be replaced on the machine grabs , put grab all the problems that exist in the management of accounting records and signatures grab a timely manner to grab supervisor.
