Garage Door Opener Trolley / Carriage in Montreal

A garage door opener trolley, also called a carriage, is the part that moves along the opener rail when the motor runs. It connects the opener drive system to the garage door arm, allowing the opener to pull or push the garage door open and closed.

If the opener motor runs but the garage door does not move properly, the trolley/carriage may be worn, broken, disconnected or incompatible with the rail or drive system.

Common signs the opener trolley or carriage may need replacement

• The opener motor runs but the garage door does not move
• The trolley or carriage is cracked, broken or worn
• The garage door disconnects from the opener
• The emergency release area is damaged or not reconnecting properly
• The opener arm is not pulling the door correctly
• The trolley slides incorrectly on the rail
• The chain, belt or screw drive moves but the door does not follow
