How to Unlock a Container House

The method of unlocking a container house depends on the type of lock, which commonly includes fixed, lifting, hinged or movable, and plug-in twist locks, requiring operation according to the specific type.

Fixed Twist Lock

The fixed twist lock is directly welded to the vehicle body, and the lock head can only rotate without longitudinal movement. To unlock, locate the handle of the twist lock and rotate it to fix the lock head at a specified angle (usually 90 degrees or 70 degrees), putting the twist lock in an unlocked state and allowing the container door to open.

Lifting Twist Lock

The lifting twist lock is fixedly connected to the vehicle body through a bracket, and the lock head can not only rotate but also extend and retract longitudinally. When not in use, the lock head can be lowered below the bearing surface to accommodate different standard container types. To unlock, first push the handle longitudinally to lift the lock head and insert it into the inner cavity of the container's bottom corner fittings, then rotate it to the specified angle to release its locked state with the container corner, allowing the container door to be opened. Some lifting twist locks have a tightening device, and before unlocking, it is necessary to reverse tighten it first so that the lock head no longer presses down on the bottom surface of the inner cavity of the corner fittings, and then perform the above operations.

Hinged or Movable Twist Lock

The hinged twist lock is hinged to the vehicle body, and the movable twist lock can adjust the fastening position. To unlock, first determine the position of the twist lock, then find the operating handle or component according to its structural characteristics, and through rotation, movement, and other operations, make the lock head detach from the fixed part of the container, thereby opening the container door.

Plug-in Twist Lock

The lock shaft of the plug-in twist lock extends into the fixed part of the container body like a pin, and it is generally used in combination with other types of twist locks. To unlock, locate the operating part of the plug-in twist lock, pull it out from the fixed part of the container body to release the fixation of the container, and then cooperate with the operations of other twist locks to open the container door.
