There are instances, where hazardous impacts simply cannot be ruled out entirely, despite implementing the highest precautions.
Parts such as counterweights, winders, and ropes can fail, causing substantial safety risks, damage to property, and production downtime. More recently, urban planning has also been concerned with the need to manage impacts, in particular those coming from vehicle-ramming attacks, which have caused casualties among pedestrians.
A specific solution for impact control has been engineered by the South African Horne Group. Technogrid is a technologically advanced impact arresting device, developed with damage control and safety in mind. Technogrid restrains dangerous collisions via predictable kinetic energy absorption, preventing damage to equipment and the surrounding infrastructure.
Engineered to strain by deforming its metal grid structure, Technogrid is able to shield both moving and stationary objects from any major damage. It can also save lives: deceleration is gradual so as to avoid critical injury to any persons situated within the moving object.
Thanks to its unique grid design, Technogrid can absorb the energy of a moving entity on impact, decelerating objects travelling at up to 120km/hr. Because the reaction force is predictable, the bars yield and bend, the units open up and undergo stroke on impact, allowing for a safe deceleration of the moving object. The technology is fully stackable: multiple units can be added in series or in parallel to absorb higher energy impacts and suit individual applications.
A wide range of impact energies can be accommodated – from 12 kJ to greater than 10,000 kJ. Highly compact and light, Technogrid can be implemented even in the most severely constrained spaces and has been comprehensively tested and proven on hundreds of sites worldwide.
Technogrid Industry Applications
Technogrid has been successfully implemented across a variety of industries, including mining, shipping, and grain storage. Its design is suitable to manage gravity forces, such as those at play in the case of conveyor belt counterweight arrest, and to decelerate moving vehicles, such as shaft conveyances.
Technogrid brings numerous benefits within industry applications by:
- Preventing serious damage to property;
- Limiting the costs associated with a halt in production;
- Increasing worker safety;
- Keep maintenance costs close to zero thanks to the absence of any moving parts. Technogrid only requires periodic visual inspection.
Technogrid has already been used as part of the following practical impact arresting applications:
- Head frame arrestors;
- Shaft overwind and underwind arrestors;
- Energy absorbers with catch gear;
- Mine station stoppers;
- Belt conveyor counterweight (GTU) arrestor for belt failures;
- General single impact energy absorption solutions.
Technogrid Urban Planning Applications
Technogrid can also be installed as an urban safety barrier to curb terrorism attempts that use vehicles as weapons of terror.
Technogrid units can be installed along pedestrian walks and seamlessly connected to features such as bench seats or street lampposts.
This urban planning application will shield pedestrians from vehicle-ramming attacks as effectively as concrete bollards or poles.
Equally important, it will guarantee the survival of the driver upon accidental impact.
Concrete bollards cause a moving vehicle to come to a full, abrupt stop which in many instances can kill the driver, who may have suffered a heart attack or brake malfunction
Technogrid can be implemented as means of terrorism protection solution because it is:
- Can be set up as a permanent barrier for infrastructure protection against deliberate or accidental impact;
- Can be hidden making it visually appealing;
- Impact G Forces are survivable;
- Safe for pedestrians;
- safe for drivers;
- visually more appealing than concrete structures, keeping cities welcoming and friendly.
Technogrid urban planning applications include high volume pedestrian flow areas, concert queue perimeters, and tunnel sidewalks.
