CM700 Series: The best alternative for CM695D/CM760D/CM765D/CM780D/CM785D power rotary heads

Deficiencies of the original machine's power rotating head: High maintenance and usage costs!

According to the original supplier's quotation, the cost for replacing the seals throughout the year amounts to several tens of thousands of yuan. The cost for major repairs is even higher. The approximate cost for replacing the main components is as follows:

Replace spindle	80,000 CNY
Replace seal/seal assembly	16,000 CNY
Replace rotary drive motor	80,000 CNY
Replace locking nut	50,000 CNY

The machine has been in production for a long time and has been out of production for many years. The supply time for its main components is as long as three months or even longer, which seriously affects the production schedule.
The maintenance was difficult, and the special tools provided could not successfully remove the main shaft joint.
The overhaul assembly technology has very high requirements.
 

Now, by replacing the original machine components with Zhigao's mining power rotary head, it only costs around 200,000 yuan to solve these problems once and for all:

Just place an order with a single part number, and we will provide a complete set of installation parts and special tools;
Professional personnel provide on-site guidance for installation.
Provide a 6-month warranty.
The cost of sealing replacement is low.
Solved the frequent oil leakage problem of the locking sleeve;
The cost of replacing the drive motor is low.
The innovatively designed locking sleeve makes it easier to remove and install the drill pipe.
By adopting Zhigao's unique spindle locking method, the spindle joint can be easily disassembled and replaced.
The structure is simple, and the major repair assembly is also simple and easy.
