Safety tips for 270 degree rotate jib crane
It is important for jib operator and owner to maintain a safe working environment. The followings are about jib crane safety tips. Safe operation can minimize injuries and provide a long life for jib crane system.
Always check whether the travel path is clear before moving the load or jib arm.
Never overload the jib crane, maintain awareness of the total capacity including rigging and below the hook devices.
Always position the jib crane carefully.
Be aware of any equipment or other personnel that may move into the path of the jib.
You should always push loads, not pull them.
Always take the lift slowly to avoid shock loading.
Always ensure that the block is over the centre of gravity.
Never use a defective jib crane or lift accessories.
Never drag a load using the jib arm, load should be cleaned of floor and obstructions.
Avoid swinging the load.
Don’t let the trolley crash into the end stops. This can cause the load to whip out which increases the effective radius, the load imposed on the structure and mechanisms.
Loads should be lowered slowly and careful for avoiding whipping of the jib arm.

Features of 270 degree rotate jib crane
1.Cover circular or semi circular work areas;
2.Are versatile enough to perform a wide variety of local handling and spotting functions;
3.Are economical enough to be dedicated to individual work stations;
4.Can increase worker satisfaction and encourage safe work practices;
5.Provide a rapid return on investment;
6.Can be a useful addition to an overload handling system, providing coverage in areas not efficiently serviced by a main crane;
7.Can relieve a main crane of many handling operations where the greater capacity and energy consumption of the larger unit would be wasted;
8.Can be effectively applied in the absence of a main crane, especially where load handling in localized;
9.Are an economical choice for outdoor installations.
Application of stable column jib crane
In work cells to provide localized material handling;
To supplement a large overload crane system;
Where overload cranes are not possible (due to lack of adequate building supports);
To transfer materials from one work cell to another;
For suspension of tools;
For economical application outdoors.
Considerations for selecting 270 degree rotate jib crane
A careful analysis must be performed. It will determine how the crane will affect the efficiency of the work area, and how it will be used in daily operation. The followings are the most important considerations when selecting a crane:
The type and extend of the structural support available;
Current and anticipated requirements for powered operation of the hoist or crane;
The characteristics and design of each crane type;
The overall height and height under boom offered;
The relative cost of each jib crane type;
The overall cost of installation.
Head assembly of pillar jib crane
Consists of two side plates, safety channel, back head plate, top head channel, upper front channel, weight bearing frame assembly, front head channel, turning roller support bracket, and a turning roller kit;
Is joined with bolts to the boom, and transfers the boom loading directly to the top pivot bearing and the turning roller assemblies;
Permits installation of the head prior to the boom;
Decreases the required installation clearances;
Allows for maximum hoist lift;
Permits for maximum hoist lift;
Permits in-head bottom entry electrification;
Large head size eliminates crushing of the trunnion rollers. Other manufacturers utilize a smaller head that can disfigure and damage the crane components, leading to difficulty with the crane operation.
