The turntable is lagging? The XGS28ACK fire-fighting aerial work platform has a precise rotation like a clock.
The aerial firefighting vehicle is most vulnerable to problems with the turntable - such as rotation jamming, hydraulic leakage, and inconsistent movements between the vehicle body when ascending and descending. This poses both safety risks and inefficiencies. Xingyu Baoyuan has developed this turntable for the XGS28ACK model. It is like equipping the aerial firefighting vehicle with a "precise steering wheel", making the 28-meter high-altitude rescue operation as stable as a pendulum.
Product core function
The turntable is the key hub connecting the vehicle lift and lowering. With a diameter of 3920mm and a thickness of 1030mm, it is internally driven by a hydraulic motor and a planetary gear reducer. The small gear drives the slewing bearing to achieve smooth 360-degree rotation. The central slip ring structure ensures that the hydraulic pipelines and wires will not kink during rotation, enabling continuous power transmission.
Technical Parameter Details
Compatible vehicle model: XGS28ACK fire high-altitude work vehicle
Model: OEM original factory replacement part
Size: 3920 × 1030mm
Core configuration: Imported bearing steel slewing bearing + hard toothed planetary gear
Three major technological breakthroughs
1.Dual-hydraulic-oil-channel motor: Adopting a cross-oil-path design, even if a single path fails, emergency rotation can still be maintained.
2.Optimized involute tooth profile: The meshing area of the gears increases by 40%, and the transmission noise is reduced by 15 decibels.
3.Maze-type sealing system: A combination of three sealing rings prevents dust from entering the bearing track. Typical
application scenarios
High-rise building fire rescue, subway tunnel maintenance, power emergency repair and other situations that require precise positioning. This Aerial Work Vehicle Part shares the same emphasis on stability as our produced Tower Crane Accessories. When operating at a height of 28 meters, the rotation error of the turntable is controlled within ±0.5 degrees.
Customized Service Example
Given the frequent starting and stopping operation characteristics of fire engines, we optimized the gear ratio of the reducer, reducing the starting impact by 30%. Last year, a certain fire brigade needed to add sensor interfaces. We integrated a signal transmission module on the side of the turntable to achieve real-time feedback of the rotation angle.
Actual customer revenue
1.The maintenance period has been shortened from 15 days to 3 days, and the spare parts interchange rate is 100%.
2.After improving the rotational stability, the efficiency of high-altitude operations has increased by 25%.
3.Shared detection standards with Underground Loader Parts, ensuring quality traceability.
Manufacturing process highlights
The rotary support seat ring is processed by a 3200mm four-roll plate rolling machine, with a roundness error of ≤ 0.08mm. The gear heat treatment adopts deep nitriding technology, with a surface hardness of HRC60. Each set of the turntable must undergo continuous 72-hour forward and reverse rotation tests to simulate five years of usage intensity.
User field verification
The captain of a fire rescue team stated: "This turntable can maintain precise positioning even in a smoke-filled environment, and it is as reliable as the Excavator Parts we use." Xiangyu Baoyuan, as a subsidiary of the world-renowned 500-strong company Xiamen Xiangyu, has all its products certified by ISO and offers 24-hour technical support.
