We started this page on 12 January, 2018 and will grow and get better over time. It needs photos too. It is definitely a work in progress.
Some comments apply to all lifts, others to only our lifts.
Tips for Winter Operation
Lifts need more attention in the winter because things can ice up and stop working.
- Before you ride a lift that has been idle since a freeze or overnight in cold weather you should ensure that the "brake dog axle" can rotate. This axle is a 1" diameter steel rod located near the top end of the dolly and has a brake dog at each end with teeth to dig into the track and stop downward motion. It usually has a red lever you can use to make sure the axle is free to rotate. Ensure the brake dogs are all the way off the track before you send it down the track.
- Clear any snow off the dolly, especially where the "Drawbar" goes through the dolly frame. Be sure that there is no ice between the Drawbar and the dolly frame.
- It's a good idea to leave the car (nearly) at the bottom of the track if it's going to sit overnight or through inclement weather: unless the car is fully loaded the motor is stronger than gravity so it's better to pull any accumulated snow or ice up and out of the track rather than trusting gravity to push it down and in. If your lift has minimal clearance under the floor in the lower station parking it near the bottom will also prevent snow accumulation that might trip the brakes.
- Some lifts are really tight at the bottom and sometimes all it takes is a small piece of ice to trip the "slack cable brakes". If this happens the red STOP light will blink on and off 2 times a second letting you know that this brake needs to be reset. We'll talk about resetting brakes later.
- If your lift has mechanical switches mounted to the side of the track these can freeze, especially in a thaw-freeze phase. In this case bring the car back up the hill a few inches after you've lowered it all the way down. This will keep it up off the "lower stop limit switch" and prevent it from freezing in it's tripped position which will stop the lift from going back down the hill.
- If the lift has been in a freeze thaw phase, after you bring it up for the first time in the day, send it down for 2 seconds empty and bring it up again. This ensures that the upper limit switches at the top have not frozen over. If the lift is frozen over work the switch level back and forth. If it flips back to it's relaxed position, lower it for a moment, and raise it again and you're good to go. If it flip back to the relaxed position call us.
- Repeat step 5 at the bottom, send it up for 2 seconds and bring it down again to ensure the lower stop limit switch is returning to it's relaxed position.
