CRANE

摘要

Daily inspections of a service truck's crane should in-clude checking all safety devices and hook safety latches for proper operation. Technicians should also check for hydraulic system abnormalities, proper oil level and any leaks, cracks or other abnormalities on the crane itself.According to Cook, maintenance should be performed on a service crane every three to four months or after 300 hours of operation—whichever comes first.During this quarterly maintenance, wear pads should be examined for general condition and replaced if necessary. Proper torque of all accessible and base mounting bolts should be checked and adjusted, and structural components of the crane should be examined closely for any necessary repairs.
