Notes: Explanations to Lifting Load
1) The rated lifting load value given in the table is the maximum lifting capacity when the crane is set
on solid and level ground. The load should not exceed 75 % of the tip-over load;
2) The total rated lifting load given in the table includes the weight of hook and slings;
3) The working radius given in the table is the actual value including the deformation amount of the boom, so lifting operation should be carried out as per working radius.
4) 75 % of the tip-over load takes into account wind force 6, i.e. lifting operation still can be carried out with fully-extended outriggers when the wind pressure reaches 125N/m2, but lifting operation with tires or traveling with load are prohibited.
SYSTEM STRUCTURE EXPLANATIONS
1.BOOM
5 section full power ordinal and synchronized telescoping boom of round U type box. The synchronization system consists of 2 telescope cylinder,2 collections of extension cables and retraction cables.One cylinder controls 2 section booms ,the other one controls 3 section booms,and 3rd,4th and 5th boom finish synchronized telescope by extension and retracted cables. Boom telescope sections are supported by nylon sliders.
Fully retracted length ——12.1m
Fully extended length —— 46.5m
Extension speed —— 200s
Root diameter —— 395mm
BOOM ELEVATION

Boom raising speed ——10°~78°,170s
2.JIB
2 stage booms swing around type with triple offset(tile type).Single sheave at jib head.
Truss type top section telescopes from the right side of base boom section.
Length —— 10.68-18.68m
