500kg wall-mounted cantilever crane rotary boom crane stone single-arm crane manufacturer BZD fixed column rotary boom crane is a kind of hoist used in conjunction with PK type chain electric hoist or CD, MD type electric hoist. It consists of a column, a swing arm, a cantilever drive device and an electric hoist. 02 02 02 02 The lower end base of the column is fixed on the concrete foundation by anchor bolts, and the motor drives the reducer drive device to rotate the cantilever, and the electric hoist performs round-trip operation on the cantilever I-beam. 02 02 02 02 BZD type boom crane belongs to light and intermediate working system. The rated workload is 0.25t, 0.5t, 1t, 2t, 3t, 5t. Different specifications and models of cranes and lifting speeds and operating speeds are selected according to the needs of the job. 02 02 02 02 BZD type boom cranes have two forms of manipulation: electric slewing and manual slewing. The rotation angle of the swivel arm can be selected from 180°, 270°, 345°, 360°, etc. according to the needs of the place of use. The BZD type boom crane has the characteristics of simple structure, convenient operation, small occupation space, large working range, etc. 02020202020202 Cantilever crane is composed of cantilever, slewing bearing, pneumatic motor, reducer, chain transmission, etc. The boom is made of steel and steel structure welded, and the boom should have high strength and rigidity. Due to the large capacity pneumatic boom crane, the cantilever length is long, so the traveling track is composed of two I-shaped steel, the middle welded steel plate, the box-shaped structure, the internal layout of the rib plate, the lower edge of the I-shaped steel is the crane trolley track. Thick flanges made of steel beam arms are used, taking into account the strength and stiffness required by the cantilever. When not in use, the swivel boom crane should be placed in a safe place. It is not allowed to hinder the operation route of other lifting equipment, let alone park it at will. Otherwise, it will be punished according to the operating regulations. All surprise repairs are strictly prohibited when the cantilever crane is in use. BZD type boom cranes are used in production lines, assembly lines, assembly lines in modern industries such as machinery manufacturing, automobiles, shipbuilding, etc., and material lifting operations in warehouses, docks, laboratories, etc. It is the ideal lifting equipment for enterprises to improve work efficiency and improve working conditions. When lifting any workpiece, the cantilever crane shall pay attention to the operating condition at any time. If abnormal noises or abnormalities occur, the crane should be stopped immediately, and promptly reported for treatment. If the operation is sick, heavier penalties will be imposed according to the violation of the operating rules. Overload lifting and oblique lifting are strictly prohibited. Observe whether the chain has a hanging card during lifting. It is strictly forbidden for people to walk under objects during lifting. After using the cantilever crane, retract the chain after the cantilever is in use. Turn off the total power after rotating the boom parallel to the base.
