Foreword
The series loader crane in the manual is designed and manufactured
by us, and the chassis connected which is made in china, the main series truck-mounted
crane including telescopic type and knuckle type.
The product have two performance of lifting and carrying, with tightness structure,
operational safety and easy to operating. It can be used in transporting, dock, storage, etc. and
also can be used to loading and unloading goods, greatly saved labor force.
You should read the manual carefully to ensure that your safety and crane working reliably,
truck-mounted crane driver, crane operator and crane maintenance man must be trained by
related man and familiar with the truck and crane operating process.
You should comply with the operating and maintenance request for truck
for the useful life of the truck.
