Production Process
 
As an BV ,ISO ,SGS approved supplier in China ,we have more than 20 years produce and export steel pole ,and we can assure the pole we offered is of sound quality which made from qualified material with our professional workers and advance equipment .


 
Material
 
All of our material are purchased from famous mill factory to assure the quality
 
A mill certificate issued by the mill factory with stamp and signature must be provided before unload the material in our factory ,otherwise we have our reason to refuse the material .
Before put into production ,all the material must pass the chemical and physical analysis to make sure that they have meet the requested strength and component.
 
Inspection
 
To assure our products qualified ,we take steps as follows :
 
1. Management team : We have employ the foreign export to take chaege of the overall managemnt ,especailly the technical managemnt and quality management .
 
2.Introducing ISO management ,We are awared ISO 9001:2008 certificate . .
 
3.QC Inpection:It is our company policy that all the finish product should be inspected by our specialzed QC in every manufacure steps and beofore every shipment.
Design and Detail
 
 Lofting and design software :We have transmisson power pole design software which can help us design all kinds of steel pole ,at the same time ,the TMA and LMA are adopted by us to provide the design the drawing accuratly

42mm DC Brushless Gear Motor mainly including 42RPBL4250 and 42RPBL4260

42mm dc brushless gear motor

Since spur gearbox or worm gearbox has a limited lifespan, and brushless motor can achieve more than 2000 continuous hours, so we merely use dc brushless motor with spur gearbox.

42RPBL4250 and 42RPBL4260 are both Dc Planetary Gear Motor, the available gear ratio including: 3.7, 5, 13, 18, 25, 49, 67, 92, 125, 181, 246 etc

Brushless motors are typically 85-90% efficient whereas brushed DC motors are around 75-80% efficient. This difference in efficiency means that more of the total power used by the motor is being turned into rotational force and less is being lost as heat.

Brushless DC motors have many advantages over their brushed DC motor counter parts. The most obvious advantage of a brushless motor is its lack of brushes and physical commutator. This difference means that there are many fewer parts that can wear out or break and need to be replaced than in a brushed motor.
