Plant Safety

GKD Technologies is a leading provider of systems designed for safeguarding personnel and machines. GKD Technologies, based in the UK, have been supplying such systems for over 25 years.

GKD Technologies is the market leader in Road Rail Vehicle (RRV) electronic safety systems, supplying systems worldwide.
The construction industry has been a key market for us during the past two decades; where we offer systems such as overload warning, height limiting, slew limiting and other motion control products, and have no hesitation in recommending GKD's products to our customers.

More recently GKD Technologies have developed Proximity Warning Systems. These systems are designed as an aid to safety through avoiding machine to personnel collision, or protecting valuable assets from collision. SensorZone, is the market leading proximity warning system in the UK.

Height & Slew Restrictors

1HLI Entry Level Height Limiter My File

The machine operator is able to define a preset limit of the machines boom on the 1HLI operator station, preventing movement of the boom outside of the pre-set limit. This entry level height limiting system monitors the angle of a single boom and provides a motion cut signal output when the angle is exceeded.

1SL Entry Level Slew Limiter My File

The 1SL SensorSlew motion control system is a simple, cost effective slew limiting solution designed to guarantee safety and prevent machine damage when operating in confined spaces.

GKD's new Sensor Height & Slew product My File

This new system monitors height and slew in real-time on the in-cab display monitor. The monitor notifies the machine operator when approaching and breaching a set limit and an external audio alarm is activated when reaching the limit. An optional intelligent motion-cut prevents infringements and allows only safe movement. And has been developed to satisfy the safety requirements of many UK principle contractors.

Rated Capacity Indicator / Overload Warning

My File

The 2RCi is a rated capacity indicator designed to increase safety during lifting operations. All lifting equipment and excavators have a specified safe working load, stated by the manufacturer, to safeguard both the operator and the machine.

The 2RCi is a flexible safety system which in its basic form is a simple load indicator - but can easily be configured to incorporate height and slew monitoring. The 2RCi is also available with intelligent motion cut facilities to control the safe movement of height, slew and or load, which satisfies and exceeds the requirements of major contractors like Interserve who require specific RCI options.

In response to changing requirements, especially for Highway construction, this latest version offers the option of a Virtual Wall' function.

The virtual wall or envelope control function can be programmed to the safe parameters of the machine's required working area, working in conjunction with the slew and height control - this prevents the excavators boom operating outside its safe-zone. This function increases the usability of the machine and allows for optimization of the 'working area'. Should the machine approach its pre-set limit an external audible alarm will warn the operator. The optional intelligent motion-cut, if installed, will stop the machine and only allow safe movement.

In addition to the rated capacity indicator functions and the virtual wall, the 2RCI provides added benefits to the user, with digging depth indication, which helps to reduce over-digging of trenches. Height limiting also allows the operator to operate in restricted headroom areas.

The system also has the option of a data logging function which updates at 1-second intervals - rental companies find this function very useful to monitor their machines.

SiteZone Proximity Warning System

SiteZone PWS uses advanced RFID technology and can be customised to meet the requirements of a wide variety of operating environments and vehicles.
SiteZone PWS produces a detection zone around a vehicle, machine or even a restricted area.
When the detection zone is breached by personnel wearing a SiteZone transponder the machine operator is alerted to their presence and can take the appropriate action. The main function of SiteZone is to warn the machine operator to the presence of risk as he is the only person that can stop the machine, however to provide an additional tier of protection there are optional warnings for pedestrians.
