Features:-
Top bearing – look for top bearings that can provide you with 10,000 hours average life that are checked by sealing in weather and dust proof steel housing attached with pressure grease fitting. Collector rings must enable continuous, uninterrupted 360º rotation. Air swivel rotation must also be looked for as an important feature. In order to reduce deflection structural construction and rigid reinforced steel plate head must be preferred.
Boom leveling must be in a way so as to provide accurate adjustment during requirements for load deflection. wear ring are almost standard for all series manual jib crane .motorized rigid support must be provided by the base plate that is connected to heavy wall column. Lower rollers that can provide precision heavy duty bearings must be chosen.
Specifications:-
Overall height: Variations from 2700 to 300 are available in general.
Length: General specification from about 1500 to 2000
Width: About 1000 to 1500
Wheel diameters are also variable based on size and capacity. Capacity variation ranges from about 500 kg to 5 tonne. An electric chain hoist is also yet another type available and has a capacity of up to 3 tonne. Changes in size and speed of hoisting varying from 550 to 575 and 5 to 2.5 respectively.
Look out for :-
- ISO certification for different parts of the crane especially for the jib.
- A long enough warranty period and guarantee given by the manufacturing company to ensure deliver of good product.
- High capacity in the crane. The general range is between 500 kg to 5 tonne.
- Space utilization consideration is important depending on how much space your work place can separate for the Manual Jib Crane.
- Long life of bearings is important for good performance and fewer faults found in the machine.
- Adjustable bottom roller assembly to set them as per individual requirement
- A strong base plate ensures a comfortable operation.
Application :-
A manual mobile Material Handling Machine suitable for Indoor and Outdoor services. It is the basic requirment in all the Motor Garages and Machine shope for loading and unloading of the Engines and materials from the Vehicles.
