Most mechanical dock levelers use snubber mechanisms to lift the lips as they are raised, and they close slowly as shocks absorb the weight of the lip. In many of the Kelley dock levelers, however, a push bar and a yieldable rod are connected to a link assembly so that when the deck is raised the push bar drops down. Then, as someone walks across to the outside of the dock leveler, the plate on the push bar catches on the middle bolt allowing the push bar to raise the lip..
Safe automatic door openers. All automatic openers must now have an auto-reversing mechanism and photoelectric eyes located near the floor on both sides of the door (see photo). If the door is closing and the beam between the eyes is interrupted, the door will automatically reverse. If the eyes aren’t connected, the door won’t operate.

Remember, not all garage door springs are alike. They are not one size fits all. If yours breaks, make a note of the brand and color code on the spring you need to replace. We'll get you the garage door opener parts you need, from seal kits to torsion and extension spring kits. Save money by replacing garage door hardware instead of replacing the whole unit.

Because it was a Saturday and I knew the garage door company I usually use wasn't open week-ends. I decided to look on the internet for week-end workers. The first site that came up was Precision Overhead Garage. Their website said if you call before noon, you can get an appointment that day. Even though it was 1pm, I decided to call anyway. After explaining that I couldn't close or open my garage door, they told me they would go ahead and schedule a time that day...even though it was after their same-day service cut off time of noon. They told me the technician would arrive between 3pm-5pm and he would call before coming (that was nice because I was able to run errands locally and not have to wait at home for those 2 hours). I also have to mention that although the company used an answering service to take the call and schedule the appointment, the gentleman that helped me was also very professional and courteous. Derrick, the technician that was assigned to the repair, called to tell me he was on his way. It was also within the arrival timeframe the company had promised. When he got to my house, he was polite and professional. He assessed the problem and made sure that I was clear about the cost of the repair and the cost of the service call. I agreed and he immediately went to work. He never tried to sell me any other services or parts or repairs that weren't needed. He was finished within 45 minutes and the door worked perfectly. I was able to pay with a credit card even without them being able to verify the information because it was a week-end. I was very impressed that they did that, especially because I was a new customer and had no history with them. Obviously, by my 5-star rating, I would recommend them to anyone who is looking for a professional garage door company. Thank you to Derrick and Precision Overhead Garage Door Service!!

The torsion springs on steel rolling doors work the same way as other torsion springs in the garage door industry. When the door is closed, the spring is wound. The spring is secured to a spring anchor bracket on one end and to the shaft on the other. When the steel rolling door opens, the spring in the barrel supports most of the door weight. The remainder of this weight is lifted by the chain hoist or the operator.
