Between the chain attachment base being set on connection balladeur train and the pulley that is arranged on door frame, the cylinder rod top of lift cylinder with
Middle door frame top is fixed together, and the bottom and outer mast bottom end of lift cylinder are hinged.
Further, the door frame is made of forklift door frame special C-shaped channel steel.
Further, the host cradle includes L bracket and rotary reducer, and L bracket passes through with rotary reducer
It is bolted together, rotary reducer drives L bracket angle modulation within the scope of 360 °.
Further, the lift cylinder is two, is symmetrically disposed on the two sides of outer mast.
The beneficial effects of adopting the technical scheme are that
The utility model structure simple operations are convenient, and processing cost is lower and the borehole investigations requirement of applicable a variety of height,
Slowed down using revolution and carries out angular adjustment, it is simple to operate to greatly improve work task efficiency, reduce worker's
The amount of labour.
