5.1 Complete Machine Vocabulary

5.1.1 girder-erectingmachine Supported on the bridge structure, the precast concrete beams can automatically change their support position along the bridge direction and be erected onto designated piers and abutments using specialized supports. A set of construction equipment.

5.1.2 railway T-girder erecting machine A complete construction system for erecting precast concrete T-beams, using railway track vehicles for traction and railway-specific vehicles for support. equipment.

Note. This includes the main unit of the railway T-beam bridge erecting machine, auxiliary units of the railway T-beam bridge erecting machine, T-beam trains, and T-beam transshipment gantry frames, etc.

5.1.3 Specialized construction equipment that can travel on railway lines and perform bridge erection operations.

5.1.4 Railway T-beam bridge erecting machine motorized flatcar Specialized construction equipment that supports T-beams and can move along the railway line on its own, transferring the precast concrete T-beams it supports to the main unit.

5.1.5 T-girdertrain Railway vehicle formation for transporting precast concrete T-beams.

5.1.6 Rail-highway T-beam erecting machine Supported by outriggers on the bridge structure, the machine can automatically change its support position along the bridge direction, enabling lateral movement of the entire beam and its application in highway and railway prefabrication. Specialized construction equipment for erecting concrete T-beams.

5.1.7 The guide beam is used for feeding the beam and for the bridge erecting machine to pass through the span. The bridge erecting machine uses a crane trolley to lift and lower the precast concrete box girder into place.

5.1.8 The guide beam is only used to pass through the span. The box girder is lifted by a crane trolley, moved longitudinally into place, and then the precast concrete box girder is installed by the bridge erecting machine.

5.1.9 Continuous moving girder erecting machine A bridge erecting machine that uses outriggers to drive the main beam to move continuously across the bridge deck to achieve span operations.

5.1.10 Step-moving girder-erecting machine A bridge erecting machine that relies on the repositioning of the outriggers and the movement of the main beam relative to the outriggers to achieve the span-crossing operation.

5.1.11 guidingbeam A bridge erecting machine that integrates beam lifting, beam transportation, and beam erection, and utilizes guide beams for auxiliary operations.

5.1.12 guidingbeam A bridge erecting machine that integrates beam lifting, beam transportation, and beam erection without a guide beam.

5.1.13 It is a specialized construction equipment used for assembling precast concrete segmental beams, consisting of a main beam, a mobile support frame, and a lifting trolley.

5.2 Component Vocabulary
