More than auxiliary.
In order to improve the lifting altitude of crawler crane and work width while improve the utilization rate of boom system, amplify out mixed
Principal arm operating mode is closed, mixing principal arm lower part is principal arm arm joint, and top is auxiliary arm joint, intermediate to be connected by a transition segment.
Existing transition segment is a special transition segment, and the sectional dimension of the transition segment one end is identical as principal arm, the other end
Sectional dimension is identical as auxiliary；It is identical as principal arm as the arm support connector of principal arm connecting pin, axis pin size simultaneously, with auxiliary connecting pin
Arm support connector, axis pin size it is identical as auxiliary.The transition segment only uses in mixing principal arm operating mode, and utilization rate is relatively low；Entirely
The costs such as boom system material and transport are higher.
Utility model content
The utility model provides a kind of general transition segment of crawler crane, which may be implemented the company of heavy principal arm
It connects, while realizing the connection of mixing principal arm, and then the special transition segment of mixing principal arm in traditional design can be saved, improve arm
The utilization rate of frame system simultaneously can be cost-effective.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution：
A kind of general transition segment of crawler crane, which is characterized in that one end sectional dimension is identical as principal arm sectional dimension, separately
One end sectional dimension is identical as auxiliary, and jointing, axis pin size are identical as principal arm between the arm support of both ends, further include spacer, institute
It states spacer to can be inserted into the pin shaft hole of transition segment jointing, internal diameter size and the auxiliary connector internal diameter size phase of the spacer
Together, the internal diameter of outer diameter transition segment jointing is identical.
A kind of general transition segment of crawler crane above-mentioned, which is characterized in that the principal arm arm head sectional dimension of principal arm system
It is identical as auxiliary.
The general transition segment of a kind of crawler crane above-mentioned, which is characterized in that the principal arm arm head jointing of principal arm system,
Other connectors of axis pin size and principal arm are identical.
