Top fork carries away several bags in the bag cargo of pile, and the situation map of the direct pile of another placement location can be transported to again.
During yoke insertion goods 25 is following, if propelling cylinder alternates propulsion, fork handle is driven before yoke
Enter, it is following until being inserted through goods.Fork truck is motionless in itself.Thus cause propulsion slide plate it is long, propelling cylinder is also long.Therefore
It can be manufactured by two kinds of structures.One kind is to promote Lengthened slide plate type, and one kind is to promote slide plate plain edition.Extended type promote slide plate be
It is to lengthen to promote the peaceful balladeur train of slide plate, propelling cylinder, yoke can be disposably provided and be inserted through the following advance distance of goods, pitched
Car is motionless.The propulsion plant and yoke total length installed on this fork truck, still can be no more than original fork of forklift truck length.Cause
Bag cargo and casing class are filled for fork, combination yoke is not long in itself, and the half of not enough existing fork of forklift truck is long.Another structure is
Slide plate plain edition is promoted, promotes slide plate not lengthen.When promoting slide plate and propelling cylinder stroke to run low, fork truck obtains signal,
Driver's driving one segment distance of advance, and yoke is motionless.Before fork truck advances, make the oil pipe on propelling cylinder inner carrier both sides all with row
Fuel tank is communicated, i.e., identical with atmospheric pressure.The oil of right section of oil cylinder is discharged into oil extraction case by fork truck in advancing by pushing plate push piston bar.
Dropped under yoke on following goods or ground, the weight of goods is pressed on yoke on yoke, and the resistance that yoke advances is very big, no
It can advance.Smooth frame is with promoting the frictional resistance of slide plate inherently very little, so only smooth frame can be slided.So, fork truck
During advance, yoke is motionless.The multiple intermittent of yoke is left pushing plate this segment distance and is eliminated in promoting.Yoke can restart
Promote.Fork truck movement promotes 1 to 2 time just.This structure, it is possible to reduce the length of propulsion plant.
The hydraulic oil needed for hydraulic cylinder on yoke is combined, oil pipe supply is involved from fork truck.Increase phase in forklift steering room
Joystick, button, the keyboard answered, to the circuit and oil circuit of control combination yoke, i.e. control combination yoke riser, are pushed away
Enter device and interdigital action.
