Available in all forms of lift, they can be operated manually (push up/pull down), by hand chain or electric.

  • Push Up - for doors up to 3500mm high or 12m, the standard method is push up with pull down rope
  • Hand Chain - for doors up to a maximum of 5000mm wide x 5000mm high (larger sizes available but not recommended if easy operation is required)
  • Electric - for all sizes of door, with 3 phase & Neutral power and low level push button operation. Single phase operation is available for less frequently used doors.

A range of control options is available, including radio control, radar and induction loop.


Support is required for the tracks and the spring units. We recommend the provision of a timber frame on masonry openings to ensure a perfectly flat surface. On steelwork the doors may be fitted direct.


  • Push up - by internal shootbolt
  • Hand Chain - by internal shootbolt and/or chain lock
  • Electric - usually omitted on electric doors although shootbolts can be fitted with electrical interlock switches to isolate the power to the motor should the door remain locked.

A key lock can be supplied (for any operation) which gives the facility for external key access.
