Car Door Drive Repair Kits

Preparation for the most common cause of lift breakdown can reduce downtime, even when only one technician is available.

The vast majority of the millions of elevators that operate worldwide every day are reliable but getting on in years. The most common cause of lift breakdown is landing- or car-door malfunction. As moving parts that are in regular contact with users, they are exposed to vandalism, incorrect operation and increased wear.

Most of the journeys undertaken by a lift are initiated by the car door, which, once the lift has halted, activates the relevant landing door by means of an actuator or skate. Many of the components that make up its drive unit are subject to high levels of use, making them prone to faulty operation. Moreover, there are many different manufacturer-specific door drives and systems available on the market, with variations even found within manufacturers.

The service technician is guided, step by step, through the details of the repair process, all the way to the mounting points of the new drive on the existing car-door transom.

When a door drive stops functioning properly, it usually happens suddenly and without warning, putting the entire lift out of order. It is, then, of maximum priority to keep the downtime as short as possible with a quick repair to restore the lift’s functionality. The best way is for the supplier of the new drive to prepare for such an eventuality by supplying easy-to- understand installation instructions that contain all the necessary steps to enable an onsite technician to dismantle the defective components and assemble the new ones. This is the concept behind the Meiller RepKit. Each is configured to enable the repair of a particular car door drive. The range covers drives from several manufacturers, concentrating on the most common models, and is continually expanded.

The repair kits consist of two boxes that contain all the parts needed to replace the defective drive parts. They include readily understandable assembly manuals, in which each individual part needed in the replacement process is clearly numbered and described. Detailed diagrams show how to remove the parts that have to be dismantled from the old drive. They also show how the new components are grouped into modules and subsequently rebuilt on the old transom. To make things even clearer, a short video showing the repair process can be accessed by a QR code.

The service technician is guided, step by step, through the details of the repair process, all the way to the mounting points of the new drive on the existing car-door transom. For this purpose, the assembly guide also contains a drilling diagram that shows, in millimeter precision, each hole that needs to be drilled.

Each model-specific RepKit is tested to successfully perform at least 100,000 door cycles. They are all powered by the Meiller MiDrive drive system (ELEVATOR WORLD, June 2018). The kit can be used to convert the company’s own earlier generations of doors (generations 1 and 2) to toothed-belt technology based on the MiDrive. Some kits also upgrade MAT drives to the new technology.
