A connector (1) for connecting a first crane (A) and a second crane (B), each crane having a boom (14), said connector comprising a first connecting arm (101) and a second connecting arm (102), the first connecting arm (101) building the top of the boom (14) of the first crane (A), the second connecting arm (102) building the top of the boom of the second crane (B), the first connecting arm (101) and the second connecting arm (102) being hinged together about only one common pivotal axis within a common pivotal plane, and wherein the booms (14) the first and the second cranes are linked up in motion in a common luffing plane, wherein the luffing plane is identical to the pivotal plane, wherein the connector (1) comprises a guide mechanism (106) configured to guide the first and second connecting arms (101, 102) to move to position the first and second connecting arms (101, 102) at a predetermined position during assembling the connector (1).
A connector (1) for connecting a first crane (A) and a second crane (B), each crane having a boom (14), said connector comprising a first connecting arm (101) and a second connecting arm (102), the first connecting arm (101) building the top of the boom (14) of the first crane (A), the second connecting arm (102) building the top of the boom of the second crane (B), the first connecting arm (101) and the second connecting arm (102) being hinged together about only one common pivotal axis within a common pivotal plane, and wherein the booms (14) the first and the second cranes are linked up in motion in a common luffing plane, wherein the luffing plane is identical to the pivotal plane, wherein the connector (1) includes a lock/unlock mechanism which is configured to one of secure and disconnect the hinged connection between the first and second connecting arms (101, 102).
A combination crane (100), comprising a connector (1) for connecting a first crane (A) and a second crane (B), each crane having a boom (14), said connector comprising a first connecting arm (101) and a second connecting arm (102), the first connecting arm (101) building the top of the boom (14) of the first crane (A), the second connecting arm (102) building the top of the boom of the second crane (B), the first connecting arm (101) and the second connecting arm (102) being hinged together about only one common pivotal axis within a common pivotal plane, and wherein the booms (14) the first and the second cranes are linked up in motion in a common luffing plane, wherein the luffing plane is identical to the pivotal plane, and two basic cranes having booms (14) and connected by the connector (1), wherein the combination crane (100) comprises a control system for monitoring the force in the pendant bars of the basic cranes.
A method for connecting the two basic cranes having booms (14) with a connector (1) for connecting a first crane (A) and a second crane (B), each crane having a boom (14), said connector comprising a first connecting arm (101) and a second connecting arm (102), the first connecting arm (101) building the top of the boom (14) of the first crane (A), the second connecting arm (102) building the top of the boom of the second crane (B), the first connecting arm (101) and the second connecting arm (102) being hinged together about only one common pivotal axis within a common pivotal plane, and wherein the booms (14) the first and the second cranes are linked up in motion in a common luffing plane, wherein the luffing plane is identical to the pivotal plane, comprising steps of:
- a) maneuvering the booms (14) of the two basic cranes such that they face each other within the same luffing plane;
- b) positioning the first and second connecting arms (101, 102) relative to each other at predetermined positions, said positioning includes monitoring the guide mechanism provided on the connector (1) by a control system to achieve relative positioning of the first and second connecting arms (101, 102);
- c) hinging the first and second connecting arms (101, 102) together, orienting a pivotal axis of the hinged connection horizontally.
