The DONGTAI crane-specific GF traveling #reducer is used for single-girder #crane operation and #hoist operation.
During assembly, the #gearbox is used as the reference, and precise adjustments are made to ensure proper meshing of each #gear stage. After the gear #shafts are installed, clearance adjustments are performed to ensure smooth #transmission and even load distribution. Special sealing materials are applied to the mating surfaces of the gearbox to effectively prevent oil leakage.
Once the complete #assembly is finished, no-load and load tests must be conducted. Smooth operation, low noise, and normal temperature rise are the basic standards for inspecting assembly quality.
Reliable assembly quality is key to ensuring the long-term stable operation of #DONGTAI reducers.

During the assembly process of #DONGTAI H-series #industrial #gearbox , a dedicated noise detection phase is implemented as a critical step to ensure product quality.
After #assembly completion, the #reducer undergoes no-load operation. Technicians use a sound level meter to measure operational #noise levels at specified distances and environmental conditions. This process adheres to standards to guarantee objective and accurate data.
The core of the #inspection lies in identifying and eliminating abnormal noises. Any unusual sounds exceeding specified limits trigger a re-inspection process. The assembly team then adjusts #gear meshing precision, #bearing assembly status, or #housing sealing to control noise generation at its source.
Passing the final #noisetest is a mandatory requirement before each H series #reducer leaves the #factory. DONGTAI enforces stringent standards for product reliability and quiet operation, guaranteeing users a smooth and silent running experience.

After assembly, #DONGTAI QY3D and QY3S series #gearboxes proceed to the surface cleaning and puttying stage. First, professional cleaning thoroughly removes oil residue, metal debris, and dust adhering to the #housing surface. Subsequently, specialized #industrial putty is applied to fill and smooth out casting seams, micro-pores, machining marks, and other surface irregularities on the housing. This ensures subsequent paint coatings achieve uniform coverage and secure adhesion. This process not only significantly enhances the finished product's aesthetic quality but, more critically, strengthens the housing's overall corrosion resistance, guaranteeing the #gear #reducer's long-term stable operation across diverse industrial environments.
