Concrete Pump Hire
We offer boom sizes from 24 to 52 metres to cover the smallest and largest of sites. The pumps are rated at between 100 and 160 cubic metres/hour to accommodate small pours as well as mass fill concrete. We offer high-pressure pumps to pump long ground-lines and can supply additional pipeline and linesmen to carry out these pours.
The most modern pumps from M34 upwards are fitted with OSS (one side support). This system allows the outriggers to be extended halfway on one side and employs an interlock to prevent the boom from slewing onto that side. When using the OSS system the footprint needed for setting up the larger machines is reduced without compromising their safe operation.
A number of pumps are fitted with boom restrictors which limit the working area of the boom. This is particularly useful when working near overhead cables or close to public areas.
M. R. Concrete’s pumps are effective with all pumpable concrete mixes including special concretes. We regularly pump lightweight concrete including Lytag®, heavyweight concrete, polypropylene fibre reinforced concrete, steel fibre reinforced concrete, foamed concrete, super-plasticised, self levelling concrete including Agilia® supplied by Lafarge, microsilica concrete including Toproc® supplied by Tarmac Topmix, low slump concrete and grout. When working with these special concretes we strongly recommend that you arrange a meeting to include the concrete pump supplier and the concrete supplier to ensure that the pump pour goes to plan.
M.R. Concrete Ltd operates a full range of mobile concrete pumps to suit each job
Static Pumps & Stationary Placing Booms
The use of static concrete pumps with stationary placing booms has increased in popularity in the UK and Ireland recently, especially for building reinforced concrete frame buildings on inner city sites where space is at a premium. Previously MR Concrete would carry out these contracts using boom pumps with additional pipeline where necessary. Now however, as a result of demand from customers, we offer static pumps and stationary placing booms complete with a full installation and maintenance service. For rc frames and large concrete structures this option should certainly be considered.
With this system, the concrete is pumped by a diesel or electrically powered, static concrete pump, through a fixed 125 mm pipeline, to the stationary placing boom. The boom is mounted on a steel column of up to 20 metres high. The column is supported by a cross base or a system of floor frames set into the concrete floors. If floor frames are used, the whole column / boom assembly can climb with the building as the work progresses. This system is considerably faster than using a crane and skip and is less likely to be adversely affected by high winds.
On larger sites, one boom can be used in conjunction with two or more columns allowing concrete to be placed over a bigger area. The boom can be readily moved from one column to the next and splits into two sections to facilitate handling by tower crane. The ability to move the boom from column to column allows an efficient cycle of work to develop of preparation, pouring and stripping shutters.
The use of stationary placing booms can obviate the need for pipeline laid out across the slab. This generally will increase the speed of each pour, reduce labour requirement and improve site safety. An additional advantage of this system is that the placing booms can easily pour walls and columns thus freeing up valuable crane time.
