Kelly bar is the key part of a drilling machine, and its quality directly affects the performance of the whole machine. The main purpose of kelly bar is to transfer the torque of rotary drive and crowd pressure of the crowd system to the drilling tool. Based on the rich manufacturing experience and by absorbing the advanced technology both at home and abroad, we can produce first-class kelly bar which can be compared favorably with the imported ones.
The features of UNIMATE kelly bar are as follows:
Adopt the advanced technology of 6-key design in the world and standard modular design.
Equipped with advanced processing facilities, workmanship and manufacturing equipments, UNIMATE kelly bar enjoys a low weight, high strength, high straightness of single bar, thinner tube, smaller inter-tube distance and good abrasion resistance.
The raw materials are either imported from Germany like the high abrasion resistance materials, or from Chinese top manufacturer such as the seamless steel tube with alloy. All the tubes made in China are specially made seamless alloy tube, which guarantees the accuracy of the sizes, location, physical properties and easy welding. The small-diameter tubes undergo reheat treatment. The friction kelly bar can be used under full torque.
All the outer keys have undergone special heat treatment; therefore, they possess higher hardness, higher flexibility and excellent welding properties, which provide higher abrasion resistance to the keys.
There are mainly two types of Kelly bars:
1-Interlocking Kelly Bar
2-Friction Kelly Bar
Friction Kelly Bar
Friction Kelly bars are used with piling rigs for drilling in silt, clay and less dense sand and gravel. The Friction Kelly bars manufactured by Unimate are un-lockable with drive keys on each section. Kelly bars can be equipped with specially designed springs or pressure plates for shock absorbing purpose.

Interlocking Kelly Bar
Interlocking Kelly bars are used with piling rigs for drilling in dense sand and gravel and weak to strong rock. The Interlocking Kelly bars manufactured by Unimate can be fully locked by mechanical locking system on each section. Kelly bars can be equipped with specially designed springs or pressure plates for shock absorbing purpose.
Foundation equipment supply (fes) kelly bars may be made in friction type and locking type, in 3, 4, 5 or 6 elements for some special occasion. For sake of common application, the external diameter is designed to be in universal dimension, such as 273mm, 299mm, 340mm, 377mm, 406mm, 419mm, 440mm, 470mm, 508mm, etc. High strength steel tube material is picked and heat-treated to arrange production, which enables the kelly bars to work well under maximum torque of the torque output. Kelly keys and guides inside kelly joints are made in highly wear-resistant material for a prolonged maintenance time. Special toolings are set up to ensure the straightness of tubes during welding process.
Now Shenwei Kelly bars have been supplied to BAUER, SOLIMEC, IMT, CMV, MAIT, CASANGRADE ,TESCAR and other drilling rigs imported or locally-made, exported to many countries such as Germany, Malaysia ,Turkey, India, Russia, Ukraine all over the world. These kelly bars are successful used even in the toughest operating conditions.

The variable pitch gear box is an important part of the fan variable pitch system, its main function is to increase the torque of the variable pitch motor on the variable pitch bearing, drive the blade to change the blade pitch Angle at different wind speeds, so that the blade is in the best state of absorbing wind energy, and can drive the blade feathering brake when the wind speed exceeds the cutting wind speed, so as to ensure the machine to run efficiently and smoothly.
The variable gear box transmission mechanism is composed of multiple planetary gear trains, usually 3 stages, and the planetary transmission form is NGW type.
