Types of operation for security shutters

There are several ways to operate security shutters. Smaller shutters may be operated manually, but larger types are typically powered up and down. Below is an overview of the main ways of roller shutter operation for different shutter types.

Domestic roller shutters | Commercial and shop front shutters (including shutters for reception & food counters) | Industrial shutters | Sectional doors

Domestic roller shutters

Roller shutters on domestic property.

With the cost of motors reducing in recent years, HVP now offers motor-driven domestic shutters at the same price as hand-operated ones.

All of our motors are fitted with a manual override facility to hand-wind the shutter in the case of a power failure.

Tape operation

A tape is connected to a drive wheel at the end of the overhead barrel assembly with the other end of the tape connected to a self locking cassette at low level. The tape is released from the cassette to lower the shutter or pulled by hand to raise the shutter. Some cassettes are fitted with a winding handle but this is generally restricted to larger shutters.

Hand Crank operation

A universal joint is connected to the end of the overhead barrel assembly and turned by a crank rod to raise and lower the shutter.

Electric operation by tubular motor

An electrical tubular motor is fitted into the shutter's overhead barrel assembly. Protruding from the motor is a manual override eye for manual operation in case of a power failure.

Spring Operation

A spring is fitted into the overhead barrel assembly and tensioned to counter balanced the shutter. Operation is by pushing up or pulling down using a handle fitted to the bottom of the shutter curtain.

Commercial and shop front shutters

(including shutters for reception & food counters)

commercial roller shutters.

With the cost of motors reducing in recent years, HVP now offer tubular motor-driven shutters at the same price as hand-operated ones. All of our motors are fitted with a manual override facility to hand-wind the shutter in the case of a power failure.

Motors used for shop front shutters are generally ones that are seated inside the overhead barrel (tubular motors). For particularly high (generally over 5m) or especially wide (generally over 7.5m wide) shutters, a tubular motor is not suitable and an externally fitted block motor is used instead.

Electric operation by tubular motor

An electrical tubular motor is fitted into the shutter's overhead barrel assembly. Protruding from the motor end of the barrel is a manual override eye an electrical wire feed and a pair of limit switches to control the maximum travel distance of the shutter curtain. Operation is generally by a key switch fitted at low level.

Electric operation by external block motor

An external block motor is fitted outside the overhead barrel assembly and drives the barrel by either, gears, chain or direct drive. Set onto the motor will be limit switches to control the maximum travel distance of the shutter curtain. The motor will also incorporate a manual override facility and an electrical wire feed.

Spring Operation

A spring is fitted into the overhead barrel assembly and tensioned to counter balanced the shutter. Operation is by pushing up or pulling down using a handle fitted to the bottom of the shutter curtain.

Industrial shutters

An industrial roller shutter.

Most industrial type shutters are either operated by a hand held chain or a externally fitted block motor. Tubular motors (see above) are generally not used as they are only suitable for shutters operated a limited number of times a day and lighter weight shutters.

Hand chain operation

A toothed cog is fitted at one end of the overhead barrel assemble and is connected to a drive wheel by a drive chain. A pull chain rides over the drive wheel and is of sufficient length to be pulled by a person standing at the bottom of the shutter. A spring is fitted into the overhead barrel assembly and tensioned to counter balanced the shutter for ease of operation.

Electric operation by external block motor

An external block motor is fitted outside the overhead barrel assembly and drives the barrel by either, gears, chain or direct drive. Set onto the motor will be limit switches* to control the maximum travel distance of the shutter curtain. The motor will also incorporate a manual override facility and an electrical wire feed.

Sectional doors

A sectional overhead door.

Also see our separate section on Sectional Doors.

Sectional doors can be operated manually by hand, pull chain or motor. Springs are fitted over a shaft at high level and act as a counter balance to operate the door. Smaller doors can by operated by pushing or pulling by hand with larger shutters being operated by hand chain or motor. For convenience we would recommend operation by motor for all installations.

Spring Operation

Springs are fitted to the overhead drive assembly and tensioned to counter-balance the shutter. Operation is by pushing up or pulling down using a hand cord fitted to the bottom of the door.
