An overview
BZ fixed column jib crane is a new product developed by our factory with reference to the equipment imported from West Germany
products, according to the needs of the user design of special lifting equipment, with a novel structure, reasonable, simple and operational
It is easy to use, flexible to rotate, large working space, etc., and is energy-saving and efficient material lifting
It can be widely used in factories and mines, workshop production lines, assembly lines and machine tools up and down and warehouses.
Wharf and other occasions several heavy objects lifting.
This machine is composed of columns, slewing arms, several chain electric hoists, etc. The lower end of the column is fixed in the mix
On the soil foundation, the swing arm rotates, and it can be rotated according to the user's needs. The swing part is divided into hands
Dynamic rotation and electric rotation (cycloidal pinwheel reducer is installed and driven on the upper supporting plate or lower supporting plate
The tube rotates the arm). The electric chain hoist is installed on the jib track and is used to lift heavy loads

2. Performance parameters and dimensions of electric chain hoist:
See the attached electric hoist "Operation and Maintenance Manual".
3. Structure and operation
This machine is mainly composed of 4 parts: column, beam, reducer and electric chain hoist.
The electric chain hoist has the function of lifting and reciprocating on the beam.
The beam can have a reducer on the supporting plate to drive the rotating pipe to run the rotary movement.
The electrical part is shown in the attached drawing: electrical principle and electrical wiring diagram. The electrical control box is installed
chain hoist.
The operation of this machine is realized by the flashlight button. The flashlight has eight buttons, which are controlled separately
Fast up, fast down, slow up, slow down, left and right rotation of a few hoist trolleys are horizontal forward and backward
Walk.
Note:
1. Do not press the fast and slow button and the reverse rotation button of the same motor at the same time during operation
2. When working, it is forbidden to stand under the crane arm.
3. It is forbidden to drag heavy objects.
4. It is forbidden to overload lifting.
Fourth, lifting
For the convenience of transportation, this machine adopts disassembly and packaging, and the user can do it by himself according to the method introduced in this book
Installation, (see "Five" Installation)
The lifting method of beam and column is shown in Figure 2, Figure 3.
5. Installation
Before installation, the product and technical documents should be checked according to the packing list
It should be corrected or restored separately, and the rotating parts such as shafts and bearings should be rotated every six months
Cleaning and lubrication.
1. The column should be installed so that the column is perpendicular to the ground, and the anchor plate screws should be
Tighten firmly, there should be no loosening, and the floor and foundation should fit well
Well, if equipped with an electric hoist, the foundation should be embedded with cables and grounding facilities
The embedded cable is drawn from the center of the foundation, and the grounding resistance shall not be greater than 4 ohms

2. Beam installation
For beam installation, please proceed in the following order.
1)
First, lift the beam horizontally and insert the shaft back from the upper and lower pallets
Bowls.
2)
Install the reducer on the pallet
3)
Install the electric hoist and the walking trolley on the swingarm beam track.
(The installation method is strictly in accordance with the "Use and Maintenance" attached to the electric chain hoist.)
Manual)
4)
Install the slip wire frame and wire rope (or C-rail) at the top of the beam
.
(The rope is strung into the slip ring and tightened, and there is a self-made gliding trolley in the C-shaped track,
And it should be on the same side as the electrical control box on the electric chain hoist
Above. )
5) Wire connection and installation of all electrical appliances on the beam, and leave a long one
degree appropriate power cord.
(See electrical schematic diagram and electrical wiring for wiring.)

After the above steps are completed, the overall hoisting can be measured
When hoisting, the lifting method specified in Figure 2 can be.
Sixth, the commissioning
After all the installation is completed, the test run can be carried out.
Before the car, add 30# mechanical oil to the rotary reducer to the median position without the standard (change it for half a year

7. Use and maintenance
1. The operator should strictly abide by the crane operation procedures and do not allow overload use.
2. It is not allowed to use the terminal baffle as a normal parking method.
3. The chain or steel rope that binds heavy objects must have sufficient strength, and the binding must be firm and reliable.
The rope or chain should be added to the acute angle of the heavy object, and the rope on the crane must be patched
In the center of the hook does not slip out.
4. The lifting and moving of heavy objects should be carried out in a vertical situation, and it is forbidden to use electric hoists
Lulai dragged or forcibly lifted heavy objects buried in the ground, and it was not allowed to turn the crane
Run drag and impact work.
5. It is strictly forbidden to stand on the top of the heavy objects, and pedestrians are strictly prohibited below.
6. When work is finished or resting, heavy objects should not be suspended in the air.
7. Every six months, the rotating parts should be accumulated on the lower wing surface of the beam (at the walking track).
Polymers, rack materials, and frame paint can be repainted or repainted depending on the peeling condition.
