The vehicles are produced by US manufacturer Holcombe Mixers to Utranazz’s specification, to meet the demands of the UK market.
The first to be released from the range is the HM12H-E, which has a carrying capacity of 9.4m3 and output of up to 50m3/hour.
Utranazz claims that it is the simplest to use and maintain volumetric mixer in the UK and it allows operators to carry the maximum amount of raw materials permitted.
Utranazz found that typically one of the most frustrating things for volumetric users was the time it takes to change a conveyor belt – two days, on average. To address this, the HM12H-E has a patented removable cassette conveyor, which is a slide-out component held in place by eight bolts. Remove the bolts and the entire conveyor assembly slides out of the back of the mixer. A new conveyor cassette is then slid in. Utranazz says that this process takes five hours.
Another feature of the HM12H-E is its load-sensing variable displacement hydraulic system, which adjust hydraulic output according to need. If the system is not in use, it is not pressurised, and thus wear parts are not made to work unnecessarily.
Standard items include: roll-over sheet, electronic measuring system, ticket printer, friction-less conveyor system, hydraulic chute control and wireless remote control.
The first HM12H-E units arrived in the UK in September and a demonstration unit is available for presentation to customers.
Utranazz says that volumetric concrete mixers offer advantages over traditional methods of concrete delivery. The volumetric concrete mixer operates as a mobile truck concrete mixer and batching plant rolled into one. Raw materials are stored in separate compartments and mixed into fresh cement where and when needed. This reduces waste as the unmixed product remains usable. Volumetric concrete mixers also eliminate the need for part load charges and problems with over or under-ordering. Customers can estimate the amount of cement needed and the exact quantity can be mixed on site, only paying for what is used. Volumetric concrete mixers can supply all mixes and grades of cement, including screed and mortar. Mixes and grades can be switched from one customer to the next or even halfway through a job if necessary.
