Product description
DXZ32/900 Self-propelled traveling formwork for bottom support Technical specifications:
1 Equipment Model DXZ32/900 Under-Carrying Self-Propelled Mobile Formwork Scaffold
2 Construction Methods Used Cast-in-place across the entire span
3 Overall Plan Support beneath the bridge deck: a formwork system supported by two longitudinal main girders.
4 Applicable Bridge Span Simply supported or simply supported–then continuous prestressed concrete double-track full-span box girders with a span ≤32.7 m and a girder weight of less than 900 t
5 Adaptation to Pier Height ≥3.5 meters
6 Adapting to Longitudinal Slope 3.0%
7 Adaptation to Curve Radius 1500m
8 Environmental Wind Pressure Requirements Wind pressure during relocation ≤ 150 N/m² (instantaneous wind speed ≤ 16 m/s)
Pouring wind pressure ≤ 800 N/m² (instantaneous wind speed ≤ 36 m/s)
9 Automation Methods Vertical jacking is accomplished using high-tonnage, split-type hydraulic jacks.
Longitudinal shifting is accomplished using a hydraulic cylinder.
The lateral opening and closing of the mold frame is accomplished using hydraulic cylinders.
Automatic forward inversion of the support leg
10 Maximum reaction force at the front support leg’s fulcrum 2 × 377 tons
11 Maximum support reaction at the rear main leg 2 × 322 tons
12 Maximum reaction force at the front auxiliary support leg’s fulcrum 2 × 40 tons
13 Maximum reaction force at the fulcrum of the auxiliary support legs 2 × 140 tons
14 Maximum reaction force at the rear auxiliary support leg’s fulcrum 2 × 110 tons
15 Total power consumption of the entire machine Approximately 65 kW
16 Power Requirements ～4AC, 380V, 50Hz
17 Hydraulic System Pressure 31.5 MPa
18 Shift Speed 0–1.0 m/min
19 Main Girder Deflection Less than L/700 (considering only concrete loads and the self-weight of the internal formwork)
20 Via Stability Factor K > 1.5
21 Transportation Conditions Most individual items weigh less than or equal to 21 tonnes, and most individual items have dimensions less than
12.5 m × 2.8 m × 1.72 m, compliant with railway and highway transportation clearance limits.
