Thanks to the OSS system (One Side Support), this PM large-boom pump can be installed and operated safely on construction sites where space is restricted. During OSS operation, the width of the front and rear support is reduced to only 9.2 m.
Concrete is pumped through low-wearing, twin-wall delivery pipes (ProLine 67 HRC, DN 117) with a life up to 10 times longer than standard pipes (ST 52) according to experience.
The remaining equipment also clearly demonstrates that powerful Putzmeister truck-mounted concrete pumps are not only characterised by their boom length. Needless to say, the M 70-5 is fitted with an EBC (Ergonic Boom Control). The EBC allows the operator to control the boom more easily using a joystick, to reduce vibrations at the vertical end hose .and to limit the working area i.e. to avoid dangerous zones.
The machine is fitted with an EOC (Ergonic Output Control) as standard. The EOC module helps the concrete pump save fuel during operation by automatically adjusting the engine to the maximum speed required for the current pumping output. If required, this speed can be increased or decreased at any time via the radio remote control, resulting in a lower fuel consumption, less wear and reduced noise levels during pump operation.
Unlike conventional hydraulic controllers, the EPS (Ergonic Pump System) on the M 70-5 controls the hydraulic drive of the concrete pump fully electronically. The simplified control hydraulics incorporate fewer components, optimise the overall pumping process and increase efficiency. In practice, this ensures a smoother “S” transfer tube changeover, less wear and reduced fuel consumption.
The Ergonic Graphic Display (EGD) on the radio remote control and the control cabinet provide the machine operator (or service engineers, if required) with information on the operating state of the machine at all times. Display parameters include the hydraulic temperature, hydraulic pressure, stroke time, engine speed, delivery pressure/limit, delivery rate/limit and operating hours to name but a few.
