Case Study - ER2 Series Hoists for EMS Systems

Client and Application Overview:

An EMS (Electric Monorail System) is a type of overhead conveyor system commonly used in industrial settings to transport materials and goods across different areas of a facility. It operates on an elevated monorail track, usually suspended from the ceiling, allowing it to move products efficiently without taking up floor space.

In the automotive manufacturing process, particularly in assembly and paint shop applications for trucks and cars, hoists play a crucial role. They are used to lift and move car bodies from one station to another, with specific tasks like dipping in the paint shop. The hoists perform essential functions such as lifting, lowering, and precise positioning. Integrated with overhead conveyors, these hoists were selected by our automation partner, who preferred Kito Hoists for their simple construction, durability, and suitability for heavy-duty, long-life operations.

Business Challenge:

Regular breakdown of competitor’s hoists due to wear and tear of chain and sprocket damage due to continuous operation.

Given the nature of the application, which involves frequent lifting and lowering, sudden starts and stops caused wobbling in the connection between the encoder and the motor shaft, often leading to coupling failures.

Other issues the customer had been facing included limited local stock availability, insufficient service and OEM support for technical solutions, and a shorter product lifespan.

Kito’s Solution:

Kito Hoists have a long history of being successfully integrated into EMS systems for clients across the world. The nickel-plated chain ensures smooth operation with minimal wear and tear, reducing the risk of breakdowns and accidents. Our hoists have single chain fall, due to which we can achieve high lifting and lowering speeds increasing the productivity.

For this application, our hoist with an internal encoder was the better solution. By offering absolute encoder instead of incremental one, we provided both technical and maintenance advantages to the customer.

Kito India's other key advantages include being the leading brand in the premium segment, with readily available local spare parts. We also have an extensive sales and service network, which supports customers across all locations.
