Tire crane slewing manipulation

This paper describes the tire as long as the crane scissor pallet truck maneuvering requirements and considerations
Rotary control
(1) Release the rotating brake pedal, the handle is turned to the desired position ("left" or "nails">, gradually increasing the rotational speed of the throttle control.
     (2) then the levers in situ, the turntable in a free state
When the rotating part of the crane in the parking brake smoothly.
     (3) rotary manipulation essentials.
     1) can be changed brake by the normally open normally closed, that the brake pedal while stepping on a tooth bit immobile (determining that a braking torque). Experienced drivers can pull the handle to the original position in advance, so that the turntable with inertial stop after a journey through to the desired determine the location, without having to depress the brake pedal again.
     2) Zhao heavy machinery driving, do not move Pallet stackers must be trampled to death. Turntable front with anti-rotation device, if necessary, can be locked to ensure driving safety turntable, but had to pull out before the rotary control latch.
     3) To enable a smooth swing operation room will make the crane turntable is level. And should not be rapid rotation. General Requirements: 6t more goods from turning when the maximum lifting rope declination <3. Master lifting 6-3t cargo slewing, lifting rope maximum declination <6 degrees rotation when lifting 3t the following goods, lifting the maximum angle rope <10. .
