Description
Slewing equipment drives are used to position driven equipment. They have been tried and tested in many unique applications, such as cranes, excavators, and drilling systems. Ever-Power gear devices for slewing gear drives possess a modular design. They are often combined with a long or short lantern equipment drive on the end result side. The mounted end result pinions are manufactured according to the customer’s features. On the input aspect, you can expect solutions for both electric motors and high-acceleration or low-acceleration hydraulic motors, a few of which already are standardized.
One frequently requested option, particularly as a gear unit for slewing gear drives in bucket wheel excavators, includes a Ever-Power planetary gear product with a bevel or bevel helical gear unit on the input area. The drive motor and a brake are arranged on a bracket on the gear device, so that the system no longer should be aligned on site. A brake is normally always mounted between your motor and the gear unit to be able to resolve the boom in a defined position. An overload security mechanism can also be provided to safeguard the boom and the drive against inadmissibly substantial loads.

Slew Drives, commonly known as a Slewing Equipment or Slew Bearings, is certainly a complete, prepared to install system that includes a ball or roller slewing band bearing, drive educate, and completely enclosed casing. It can be custom-made with hydraulic or electric motors, brakes, planetary gearboxes, corrosion protection, and also many other options.
Ever-Power lower costs by replacing sophisticated in-house systems in devices that rotate hefty loads and require operation and innovation. Each has an unlimited slewing position and range, move easily and jolt-free, no slip-stick impact, and provide the most efficient transmission of high electricity and torque feasible. Our Slew Drives will be completely enclosed and sealed casing withstands harsh environments and increases safety.
As a ready-for-installation system module, they replace many individual parts. Slew drives are utilized for aerial platforms, protection technology, public transportation, forestry equipment sectors, solar trackers, and much more.

Slewing equipment drives for just about any power rating and mounting position
For larger equipment, the slewing equipment drive can be made up of various gear units that effect on the same girth equipment with external or internal teeth. We offer the right combo of gear models for every requirement:
Our P series commercial planetary gear products and the X series commercial bevel equipment and bevel-helical gear devices are enough for smaller torques of up to 500 kNm. A combo of XP series professional planetary gear products and X series industrial bevel-helical gear systems provide larger torques of up to 4,000 kNm.
Slewing equipment drives are generally shaft-mounted designs. This implies that the gear unit is mounted at the top and the pinion on underneath. However, our drive choice is also obtainable as a bottom-mounting variation or “bottom-up” version – in this instance the pinion is put at the top. The lubrication, oil expansion tank and the seals happen to be adapted to the mounting position.
