This guide will help you maintain garage and industrial doors safely, quickly, and comprehensively. Everything is explained in clear steps, including checklists, intervals, and internal links to suitable spare parts.

Maintenance intervals

The intervals depend on usage and environment. Heavy traffic or dust shortens the intervals.

Basic maintenance in 7 steps

1) Secure the system

Disconnect the power. Secure the gate against movement. Affix a warning label to the drive mechanism.

2) Visual inspection

Check rollers, hinges, cables, and seals. play and corrosion.

3) Cleaning

Clean the rails with a dry cloth. Ensure there are no greasy residues on the running surface.

4) Lubrication

Lightly oil the pivot points. Apply a small amount of grease to the bearings. Do not grease the guide rails.

5) Fasteners

Check the screws on the hinges and roller brackets. Tighten to the specified torque.

6) Test sensors

Interrupt the light barrier. The gate must stop and open. Trigger the closing edge at three points.

7) Trial run and documentation

Open and close the gate several times. Check the noise and operation. Record the results in the log.

Lubrication and cleaning

Proper lubrication reduces wear. Too much grease attracts dust.

What to lubricate

•           axles of the rollers

•           Hinge pivot points

•           Spring bearings, not the spring coils

What to clean

•           Guide rails with a dry cloth

•           End strips and seals

 Housings of sensors and reflectors

What to avoid

•           No oil on the guide rails

•           Do not use a pressure washer on seals and electronics.

•           Do not use silicone-based sprays on brake surfaces.

Test points according to assemblies

Roll

The rollers must run smoothly. Lateral play should be minimal. Replace them if they have any detents or flat spots. Replacement rollers are available. Check the axle diameter and material.

Hinges and roller holders

Check for gaps and play. Lightly grease bearing surfaces. Tighten screws. Spare parts can be found under Hinges.

Wire ropes

Check for broken strands, rust, and stretching. Inspect ropes in pairs. Check pulleys for free movement. Suitable ropes: wire ropes. Pay attention to length, diameter, and end clamps.

feathers

Visually inspect the springs. Note any gaps, paint chips, and uneven settling behavior.

Spare parts and accessories: springs, clamping irons & mandrels.

Seals

Clean the bottom and side seals. Replace any porous or torn seals. See gap seals for sectional doors and door seals.

Safety sensors

Test the light barriers with a test piece. Clean the reflectors. Check the alignment. For industrial doors, use light curtains to shade the entire height. Trigger optical sensors at three points on the closing edge.

Typical mistakes and solutions

The gate jerks or squeaks

Check and lubricate the rollers. Grease the hinges. Tighten the screws. Clean the rails. The gate does not close completely. Remove dirt from the rails. Check the seals. Verify the end positions.

Security breach without apparent cause

Clean the reflectors. Check the sensor cable connections. Test with a spare coiled cable.

The goal is crooked. Check wire ropes in pairs. Check pulleys. Avoid different rope lengths.

Corrosion spots on the gate leaf

Clean and dry the area. Touch up with a paint pen. Apply a protective film.
