Gate / Doors
Through tried and tested associate companies we are able to offer installation and PPM (planned preventative maintenance) of automated gates & doors.
Gates
Gate openers can be the rollback (sliding) type that retracts a gate along the fence or wall on wheels or bearing or the swing type that draws the gate open or closed on hinges. They are usually operated by a remote controller or a sensor. There are different types
- Articulated
- Underground
- Sliding
The backbone of any electric gate, whether automatic or not, is the electric gate motor, two distinct motor types exist hydraulic, or electromechanical. This is the electric device which enables the electric gate to open and close without having to manually push the gate.
The safety of an automated gate is an important consideration. An automated gate that has not been fitted with safety in mind can potentially become a major hazard, particularly to untrained users. Various safety devices are available to make sure that your gates meet safety standards. These include sensors, ground loops and safety edges.
The controls surrounding your gate can be as sophisticated, but even standard packages offer versatile choices that will deliver gates that are safe, convenient, and secure.
Keyring transmitters that can open the gates from around 100m away are the most common form of control. For exiting, the transmitter can be used or the gate can be triggered by a ground loop that vehicles drive over when approaching the exit.
With a GSM controller added to the automation, you can also divert the operation of the gate through your mobile phone, allowing access by nominated phone users too.
A simple text command can keep your gates open for an assigned period and there’s the added advantage of text and email support from Innertec.
Doors
Sliding door operators are typically used on the outside doors of large retail businesses and residential buildings
A door operator may be triggered in various ways:
- Approach Sensor – the door opens when a user approaches it.
- Pushbutton – the door opens when a user presses a button.
- Access control – the door opens when an access control system determines the user is authorized to go through.
- Automatically (in the case of elevators).
A trigger from any of the above requests that the door be opened (or reopened if it was closing).
Sensors can be used to detect obstacles in the path of closing doors. The simplest sensor consists of a light beam aimed across the opening: when the beam is broken by an obstacle, the operator prevents the door from closing. Infrared and radar safety sensors are also commonly used. Other sensors such as resistance-sensing motors can be used to reverse the closing action of the door after an obstacle is encountered.
The operator is placed in the space above the sliding door.
An electric motor, geared down to get a lower speed and a higher torque, drives a pulley at one end of a belt. The door is clamped to the belt. To open the door, the motor turns the pulley, which in turn turns the belt, which in turn drags the door. To close the door, the reverse occurs.
Historically, elevator doors were opened using simple harmonic motion by a set of mechanical linkages; the motor, geared down, would rotate linked arms, which in turn would drive the door.
