Introduction to model and performance of bridge erecting machine:
There are four specifications of highway bridge erector according to the erection span: 30m, 40m, 50m, 55m, and the corresponding erection tonnage is 100t, 110t, 120t, 140t, 150t, 160t, 180t, 200t, 220t, etc. In the above four span specifications, the main girder structure is triangular truss. (it can also be a hollow box type, but as a professional manufacturer, from the perspective of our many years of engineering practice experience, we first introduce the triangle truss double girder structure to the users.) in addition to the above span and tonnage, we can also design any tonnage and any span according to the actual needs of customers, so as to meet the requirements of customers' complex terrain construction and bridge erection, such as curve bridge erection, uphill bridge erection, etc The whole bridge erecting machine can climb, turn and stretch.
At present, as far as we know, construction and double girder truss bridge erecting machines at home and abroad can be roughly divided into three types from structural form, construction method and working condition. Here, we use our factory's standards and identification methods to introduce these three models, namely: "J, Q, J". The identification methods are: JQJ bridge erecting machine, "30m" represents the actual erection span, "100t" represents the maximum erection tonnage, "J, Q, J" represents the bridge erecting machine model.
The bridge erecting machine must be equipped with front and rear transverse moving rails, and the beam carrier shall be used to feed the beam. The transverse moving rails and the beam carrier are optional parts. The cable inside the bridge erecting machine is provided by the user.
Special note:
As a special equipment that can complete the operation under complex conditions, the shorter the main beam, the better, the shorter the main beam, and the better to adapt to the working conditions; II (a) the main beam is the shortest at home and abroad; on the premise of the shortest main beam, it can also realize the self parallel through-hole, which needs technical support, II is the representative and the model; II (a) the main beam is the shortest at home and abroad; Through hole and side beam erection are the two most risky actions of bridge crane. Self parallel through hole and side beam erection are the unique skills of II bridge crane;
