7 Inch Single Axis Hourglass Worm Zero Backlash Slew Drive For Construction Machinery
Single Axis Hourglass Slewing Drive Description
Due to the diversified needs of the full-circle rotary reducer products in the domestic construction machinery field, Hangtuo has developed a rotary drive that can adapt to the use of construction machinery, and can be used in hoisting, lifting machinery and excavator tooling attachments. The rotary reducer for construction machinery overcomes the shortcomings of low efficiency and large wear of the original worm gear transmission, and combines the heavy load characteristics of the enveloping worm transmission, which can further reduce the size of various construction machinery and further improve the efficiency. For low-speed and heavy-load excavator tooling and lifting and hoisting machinery, we recommend Hangtuo's envelope worm rotary reducer.

Advantages
1. Rotation 360 degrees
2. Connection of a driving motor from the left or right side,
3. During installation, it is not necessary to adjust the gearing clearance; this is already set by the producer before factory
4. Simple installation and low maintenance
5. Rational space utilization
6. The gear is self-locking; therefore a brake is not necessary
7. Easy and fluent method of starting and stopping
8. High accuracy
Application Scope
Typical applications include solar trackers, wind turbines, satellite and radar dishes, truck cranes, man lifts, utility equipment, hydraulic equipment attachments, oil tool equipment, tire handlers, digger s, and automotive lifts.
