Electric Robotic Demolition- Power and Control in Perfect Harmony

Robotic Demolition Solutions - NationwideGnat UK specialise in areas of demolition where restricted access or environmental hazard make conventional methodsimpractical. To this end, our remotely operated, electro-hydraulic Husqvarna and Brokk fleet provide the optimum solution, delivering impressive technological benefits over conventional demolition systems:

• Exceptionally powerful 3-phase electric motor for quiet, focused hydraulic power free of harmful diesel fumes

• Remote operation facilitates increased operator safety and efficiency for precise controlled demolition

• Their compact and manoeuvrable design enables safe access and demolition in confined spaces inaccessible to conventional plant

• Remote operation eliminates the harmful vibrations associated with hand & arm vibration (HAVS) & White Finger Syndrome

• Custom designed to accept a range of versatile attachments from powerful percussive breakers to hydraulic crushing jaws, loading buckets , concrete milling heads and more

The Legacy of ExperienceHaving operated robotic machines exclusively since 1990, Gnatis one of the leading exponents of the technology in the UKtoday. We operate one of the largest fleets of electro-hydraulicrobots in Europe, with capabilities and applications across awide range of service industries and civil engineering projects

In addition to providing plant on a with-operator basis, Gnat UKhas a proven track record in the provision of plant contractingservices, offering expert advice and practical solutions to customers across industry

Removal of Contaminated Waste during

decommissioning of Vesselsleft and belowBrokk 90 deployed to wreck and remove refractory linings during decommissioning of numerous vessels on a toxic site

To facilitate access and removal, a hole wascut into the side of the vessel and afterwrecking, an electric Bobcat deployed to remove waste through an opening cut intothe floor

Toxic dust was effectively controlled by use ofa pneumatic water suppressant system

Tunneling Operations - Mersey Tunnel ProjectThis complex project involved the boring out of Interconnecting Safety Tunnels between the twotraffic lanes at the heart of the Mersey Tunnel

Access time was at an obvious and unavoidablepremium, working conditions were crampedand ventilation in the confined working areawas limited!

Gnat UK's rubber tracked Brokk 250 proved theideal choice owing to its combination of small footprint, focussed power, manoeuvrability andfume-free 3 phase electric power source

The Gnat UK team surmounted the difficult access problems, completing project safely,quickly and within budget

Electric Robotic Demolition- Powerful, Manoeuvrable, Versatile, Precise

Gnat UK has the largest fleet of Brokk and Husqvarna robotic demolition machines in Europe for hire with or without operator

We have a rolling investment strategy in 'State ofthe Art' remote demolition technology and have recently added three Husqvarna Remote ControlDemolition machines to our fleet- Two Husqvarna250's and the compact Husqvarna 140

The smaller Brokk and Husqvarna machines areideal for access via scaffold, or through the frontdoor!, whilst the Brokk 330’s, (each weighing in atnearly 4 tonnes) deliver the power of conventionalexcavators that are four times their size!

Attachments Fit for Purpose!All our robotic demolition machines are customdesigned for use with a variety of purpose built attachments to tackle the most demanding deconstruction task you can throw at them!

Attachments range from powerful percussivebreakers, percussive drills, hydraulic crushingjaws, grapples, loading buckets and concretemilling / scabbler heads and more

Gnat UK utilised a newly developed Diamond Wire

Sawing Machine to remove sections of brittle,

1100mm diameter cast iron water main - embedded

in a concrete saddle and lying just 660mm from a

similar live pipe carrying one of the city's main

water supplies! Completed in a fraction of the time

needed by conventional milling machines and at

one third of the cost!
