Fix after stating the first fixed pulley, the second fixed pulley and being arranged on the movable pulley below described second fixed pulley
Being connected on lift heavy crossbeam, described movable pulley connects has lifting frame, with described lift heavy on described pole
The side that crossbeam is relative is installed with claw type auxiliary stand, and the top of described pole is provided with lightning-arrest
Pin, the top of described pole is provided with becket bridle, and the end of described lift heavy crossbeam is by strengthening rope and rope
Ring is connected.
Above-mentioned a kind of rotatable simple pole crane, it is characterised in that: described lift heavy crossbeam is straight
Angle ladder beam.
Above-mentioned a kind of rotatable simple pole crane, it is characterised in that: described claw type auxiliary stand
Including cross bar and the brace being symmetricly set on described cross bar both sides, it is connected between described cross bar and brace and has
Reinforcement.
Above-mentioned a kind of rotatable simple pole crane, it is characterised in that: outside described pivoting support
Circle is fixedly mounted on described base, and the inner ring of described pivoting support is fixing with described installing plate to be connected.
This utility model compared with prior art has the advantage that
1, this utility model is simple and reasonable, it is easy to processing and fabricating, novel in design, turns at needs
Installing plate only need to be promoted time dynamic to rotate, and the bearing of trend of lift heavy crossbeam changes therewith, it is possible to achieve
360 ° of rotations, to reach hoisting operation requirement, this pole crane can be in limited construction space
Being efficiently completed the lifting carrying of plant equipment or weight, using effect is good.
2, in this utility model, lift heavy crossbeam is preferably the right-angled trapezium beam of upper flat slanting, and lift heavy
Crossbeam is relatively big with the area of pole junction, therefore relatively can reduce the flexural deformation of lift heavy crossbeam root,
The structure making this pole crane is the most reliable, it addition, also can be according to job site practical situation needs
Lifting frame is replaced by lifting hug, and easy to use, cost of manufacture is low, can be applicable.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
