Crane or similar manipulating apparatus with integrated assembly for overcoming each dead position between primary and secondary part of its operational arm
A crane apparatus with an integrated assembly for overcoming each dead position between primary and secondary parts of its operational arm includes a bearing framework attached to a chassis and is furnished with at least two telescopic supporting legs that are vertically arranged, and a bearing mast that is connected with the bearing framework, and an operational arm is attached in a pivot point and pivotable around a horizontal axis. The operational arm includes a primary part and a secondary part that are pivotally connected with each other. The secondary part is pivotal around the horizontal axis connected with the primary part of the operational arm via a dead position overcoming assembly that includes a rotational driving subsystem as well as a mechanism that is attached to part of a hydraulic cylinder for pivoting relative to the secondary part of the operational arm.
Jib assembly
A jib assembly includes a support; a jib attached pivotally to the support for pivotal movement of the jib in relation to the support about a horizontal axis; a first linear hydraulic actuator attached to the support for regulating pivotal movement of the jib and for maintaining the jib in a specific position relative to the support; a lever arm attached unrotatably to the jib; and a draw member attached to the lever arm and to the jib; wherein the first linear hydraulic actuator is attached to the lever arm, and the lever arm is arranged to extend in the direction above the jib.
