2 ton Mobile jib crane
Spiral boom crane
Jib crane is also called boom crane, is a small and medium-sized lifting equipment developed in recent years, the structure is unique, safe and reliable, with high efficiency, energy saving, time saving, flexible and other characteristics, three dimensional space within the random operation, in the distance, dense transport occasions, than other conventional lifting equipment shows its superiority. It is widely used in different places of various industries.
An overview of the
The working strength of the rotary arm crane is light, the crane is composed of the column, the slewing arm slewing drive device and the electric hoist, the lower end of the column is fixed on the concrete foundation through the anchor bolt, by the cycloid pin wheel deceleration device to drive the rotary arm, the electric hoist in the rotary arm I steel for about straight line running, and lifting heavy objects. The crane arm is hollow steel structure, light weight, large span, large lifting weight, economic and durable. Built-in MOde-type walking mechanism, using special engineering plastic wheel with rolling bearing, small friction force, walking fast; Small structure size, especially conducive to improving the hook stroke.
Classification
Boom crane is a new generation of light lifting equipment made to adapt to modern production, with high reliability of the chain electric hoist is especially suitable for short distance, frequent use, dense lifting operation, with high efficiency, energy saving, trouble saving, small footprint, easy to operate and maintenance, etc..
Fixed column rotary boom crane
1, fixed column type cantilever hanging
2, curved arm type cantilever hanging
3, wall cantilever hanging
4, gantry type cantilever crane
5, mobile cantilever crane
6, double arm cantilever hanging
7, wall row type cantilever hanging
Safe operation
All safety specifications for crane use and operation shall be observed when operating a boom crane. To ensure safety and avoid damage to the equipment, please follow the following safety instructions.
The use of boom cranes for personnel transport is not permitted.
Do not lift heavy loads above personnel. Do not slant or drag the load.
Overload is not allowed.
Avoid bumping the limit switch when lifting the hook during normal operation.
Other important operation tips: the load spreader must be hung on the trolley by flexible connection. The rigid connection mode can produce uncontrollable forces and eventually lead to fatigue fracture.
Do not pull the flashlight door when it is loaded. When the spiral arm is manually rotated, only pull the hook. Do not pull the flashlight door and cable.
The fasteners on the boom crane should be checked and fastened once every 6 months.
Maintenance
For safety and high altitude operation, please specify the maintenance plan of the equipment according to the actual situation, and check it at least every six months or a year according to the following key tips.
1. Bolt connection line, anchor bolt connection, bolt connection with stop end cover. Bolt connection for screw arm installation, bolt connection for drive device installation.
2, fit and wear parts hoist, trolley/bearing beam to take the pin connection of tight fit and wear. Motion mitigation and wear of trolley wheels, rollers and cantilevers. Generally, lithium or calcium based grease is added once after 6 months of use. Electrical equipment inspection, including cable slider wear, flat cable damage, etc.
3, the wear of the stop.
4, the inspection and maintenance of electric hoist, the inspection and maintenance of electric hoist should be carried out by the designated personnel, according to the corresponding provisions of the use of electric hoist, chain and walking drive device.
5, when the damage is found in the inspection of more than the specified value of the parts should be replaced.
