When it comes to hydraulic elevators, safety and reliability are paramount. A recent installation of SMD’s combination level/temperature switches in a 7-story hydraulic elevator in Missouri highlights how our technology is transforming elevator operations. Here’s a closer look at this specific application and how SMD’s switches are making a difference.

Hydraulic Elevator

 

The Challenge: Protecting a 7-Story Hydraulic Elevator 

Hydraulic elevators are commonly used in low-rise buildings (up to 9 stories) due to their cost-effectiveness and reliability. However, they rely heavily on hydraulic oil to function, and any issues with oil levels or temperature can lead to system failures, safety risks, and costly downtime. 

In this specific case, the elevator’s hydraulic pump station required a reliable solution to: 

  1. Monitor Oil Levels: Detect when the hydraulic oil level is too low, preventing the elevator1 from reaching selected floors. 
  2. Control Oil Temperature: Ensure the oil doesn’t overheat, which can degrade performance and damage the system. 

The Solution: SMD Combination Level/Temperature Switches 

SMD’s combination switches were installed to address these challenges. Here’s how they work in this specific application:

Low-Level Oil Detection:

  • The low-level switch continuously monitors the hydraulic oil level in the tank. 
  • If the oil level drops below a safe threshold, the switch triggers an automatic shutdown sequence: 
  • The elevator safely returns to the bottom landing. 
  • Passengers are allowed to exit. 
  • The system shuts down completely, preventing further operation until a technician can investigate and resolve the issue. 

This feature ensures that the elevator never operates with insufficient oil, protecting both passengers and the system itself. 

 

High-Temperature Protection 

  • The temperature switch monitors the oil temperature in real time. 
  • If the oil temperature exceeds 160°F, the switch triggers a shutdown to prevent overheating. 
  • The system remains offline until the oil cools to a safe temperature, ensuring optimal performance and longevity. 

Why Major Global Elevator Manufacturer Chose SMD 

Global leaders in elevator manufacturing, chose SMD’s combination switches for this installation because of their: 

  • Reliability: Built to withstand the demanding conditions of hydraulic elevator systems. 
  • Precision: Accurate detection of oil levels and temperature ensures safe and efficient operation. 
  • Ease of Integration: Compatible with third-party equipment like MEC controllers and Canton Elevator switches, making them a seamless addition to existing systems. 

The Results: Enhanced Safety and Reliability 

Since installing SMD’s combination switches, the 7-story hydraulic elevator has experienced: 

  • Zero Incidents: No cases of low oil levels or overheating have been reported. 
  • Reduced Downtime: Automatic shutdowns and alerts allow for quick resolution of issues, minimizing system downtime.
  • Improved Maintenance: Technicians can quickly identify and address problems, reducing maintenance costs and extending the system’s lifespan. 

  

Who Else Can Benefit? 

SMD’s combination switches are ideal for companies involved in the design, manufacturing, and maintenance of hydraulic power units (HPUs) for elevators. If your company specializes in: 

  • Hydraulic Power Units for Elevators: Ensure safe and efficient operation with reliable oil level and temperature monitoring. 
  • Elevator Power Units: Enhance system performance and reduce downtime with advanced monitoring solutions. 

Now it’s your turn to join them!
