Cantilever Sliding Gates

A cantilever gate is a gate which slides along horizontally and is capable of extending beyond its vertical support post. The cantilever gate is used where there may be issues with uneven ground or open spaces where the gate opens into and the traditional use of bottom track guides is not possible. If a track cannot be fitted across the entrance then a cantilever gate is also the solution if swing gates are not used.

The gate slides across the opening and then engages into a receiving vertical post stop which then ensures the gate cannot be forced or fall downwards. The use of various roller wheels holding the gate stable during operation is a key part of the design and the supporting post which the gate slides through is secured by a sizeable concrete foundation.

Drive and Safety

Most cantilever sliding gates will be electrically operated and the rack and pinion system is used for this with a motor drive fitted at low level driving the racking system fitted to the length of the gate. All sliding gate systems must be fitted with appropriate safety systems sometimes dependant on the design of the gate (i.e. open bar design or solid panel) and the environment in which it is used. Open style gates will basically give more chance for entrapment, period.

Safety features always include a leading edge obstacle detection system, infra red beams and anti entrapment features.

AGD Systems have installed many cantilever gate systems in domestic and commercial applications and with the minimal stresses on the sliding gear these gates are very durable with long life spans and minimal maintenance required.

Materials

Most cantilever gates will be manufactured from steel or aluminium but we can also provide timber gates if required, although we would always recommend a hardwood such as iroko, idigbo or similar rather than the unstable softwoods. Often the best solution is to clad a steel framework to ensure stability and security long term, whilst giving the option for easier repairs and maintenance. The lighter the design of the gate the easier the whole system will be too install whilst keeping costs down for groundworks and steel work.

Generally a cantilever design can provide a gate width of up to 10 metres wide. The totally smooth and almost silent operation is also a benefit in many applications.

Ideal Usage

Farm Entrances

Access control where the roadway is lower than the pathway either side

Palisade fencing with gated entrances

Factory and Warehouse entrances

Entrances where a totally level ground is required for vehicle entry

Forklift access

Domestic entrances with block paving or cobblestones which don’t want disturbing

Any opening with uneven ground surface which cannot easily be addressed.

Design

AGD Systems can provide almost any design for a cantilever gate as there is no standard size, design or style. Flat top, curved top, open pattern, closed pattern, round bar, square bar, 5 bar, steel, aluminium or timber. The design may well be determined by the surrounding fencing or features but in theory any design can be accommodated within reason.

Security

In most cases any form of horizontal sliding gate is a far better solution for physical security as forced entry from outside is very difficult when the gate is always held in the steel posts either side providing maximum lateral resistance. The rack and pinion automation systems used provide very good security against any forced attempts too.

Access controls in the 21st century all have encoded transmission systems and any hardware used such as keypads or swipe cards also use the very latest encrypted technology.
