Final tests for Manitowoc 31000

The 2,300 tonne capacity Manitowoc 31000 crawler crane is nearing the end of its test programme, including boom and jib combinations which are the longest ever designed for a Manitowoc crane.

Mike Wood, senior product manager said: “We have designed the 31000 to be as adaptable as possible. The crane is available with multiple boom and jib configurations, as well as five counterweight configurations.”

Three boom configurations maximise flexibility of the Manitowoc 31000 crawler crane.

The 31000 comes standard with a 55 metre heavy-lift main boom, but using optional five and 10 metre inserts, the main boom can be extended to a total length of 110 metres.

Optional boom configurations can also increase the crane’s reach and lift height.
The first attachment is a fixed jib with a basic rating of 1,400 tonnes and a basic configuration of 24 metres. Otional inserts extend ot to 42 metres.

A luffing jib is also available starting at 36 metres, it can be extended to 114 metres. Maximum capacity on the luffing jib is 1,100 tonnes.

The 31000 also has a combination boom, which uses parts of the main boom and the luffing jib. With various inserts, the combination boom has a maximum length of 138 metres.

“We are utilising much of the luffing jib for the fixed jib, and many of the boom sections and boom top of the luffing jib are used in the combination boom, thereby ensuring maximum utilisation,” added Wood.
