An innovative grab solution like no other

Aligning perfectly with our values of safety and sustainability, this unique and innovative grab hire solution allows us to make further positive contributions to the country’s waste recycling and renewable energy sectors.

Cadman Cranes specialise in tank clearance, dredging, back filling, and material re-handling. We specifically designed a remote-controlled hydraulic power pack grab attachment, mounted on the hook of our mobile cranes, allowing us to handle up to 100m³ of material a day, reaching distances of up to a staggering 60 metres.

The system can be used in a live environment removing the risk of confined space entry and expensive drain-downs or isolations.

Providing integral support to the wastewater industry

The wet wipe destroyer!

This innovative grab hire solution enables us to handle materials such as silt, stone, sand, grit, vegetation and the by-products of waste and wastewater treatment including non-flushable fabrics, sludge, slurry, wet wipes and sanitary towel build ups. Ideal for the removal of material from sewage and effluent treatment plants.

We are the only mobile crane hire company in the UK that can offer this solution and have proven time and time again to be an integral part of the wastewater industry.

We can access the tightest, most remote areas with our revolutionary Compact Crawler Cranes. Equipped with a fully rotating re-handling hydraulic grab and rubber tank tracks, these specialist pieces of machinery allow us to offer a grab crane capable of handling the most unsuitable ground conditions whilst performing tasks other cranes just cannot execute.

Case Study

Below the allotments in Manchester Drive, Leigh on Sea, lies a 14m diameter, 14m deep storm water wet well collecting much of the surface water from the area before pumping it towards the Thames.

The engineering solution was simple enough – two of our Compact Crawler Cranes or ‘Thunderbirds’. One for access and material handling and the other as a standby in case of breakdown or emergency rescue.

Case Study

We were contacted to assist with the refurbishment of eight aeration grids at Canvey Island, Essex. The client required a safe solution to efficiently remove grit and rag from the bottom of the tanks whilst keeping the tanks operational for the duration of the works.

Find out how we designed and commissioned a unique hydraulic power pack which could be used with a conventional mobile crane, attaching to the hook block, allowing us to handle up to 300m³ of material up to distances of 60m.
