Free-flow Hydraulics


Benefits at a glance

  • More power and less energy lost
  • High efficiency
  • While valves interrupt the oil flow on other systems, the intelligent control directs the oil into the drive cylinders without significant losses
  • Expensive control blocks are not required which avoids the oil heating up and makes servicing easier
  • Powerful and convenient operation

Today concrete pumps are predominantly operated by hydraulic systems. Putzmeister places its trust in the benefits of free-flow hydraulics because the most important performance factors are the concrete pressure, low-loss oil delivery and costs.

When large quantities of concrete are pumped, large quantities of oil also flow inside the hydraulic system. More power is transferred inside a closed free-flow hydraulic circuit because the oil is conveyed from the pump to the drive cylinders without loss. The adapted hydraulic System ensures extremely powerful interaction between components. Compared to the open circuit, this ingenious drive technology requires significantly less oil and does not generate as much heat. The system is also economical to operate because it achieves a high degree of energy efficiency and is easy to service.

 

 

Ergonic® Control System by Putzmeister

Greater efficiency, lower costs, increased flexibility – these are the results that Putzmeister truck mounted and stationary concrete pumps with Ergonic® systems can achieve in practice.

Standard equipment:


Ergonic® Remote control: Within your grip!

  • Ergonomic boom control with two joysticks
  • The EBC functions can be directly operated using the radio remote control. When EBC operation is activated, it is possible to control the boom with only one joystick.
  • The pump operator receives up-to-date feedback and system displays for the machine directly on the clear display
  • Simple operation of the entire display menu via rotary push button

 

EPS - Ergonic Pump System: Advantages at a glance

  • Low wear
  • Vibrations in the machine and boom are reduced
  • Minimal noise during the optimised pumping process
  • Includes EOC (Ergonic® Output Control) - regulates the engine to the perfect speed to minimise fuel consumption, wear and noise
  • Fault management via EGD (Ergonic® Graphic Display)
  • Fewer components and therefore lower service costs
  • Convenient radio remote control incl. replacement cable remote control
  • Practical and reliable fault management
  • High degree of machine availability due to high-quality components and easy access to data via optional Ergonic® Tele Service (ETS) for rapid (remote) diagnosis

 

EGD - Ergonic® Graphic Display: Provides a full overview

Simple control and increased operational safety

It provides information about:

  • Hydraulic fluid temperature
  • Operating hours
  • Delivery pressure/delivery pressure limit
  • Delivery rate/delivery rate limit
  • Fault management
  • And much more information

Optional equipment:


EBC - Ergonic Boom Control: Advantages at a glance

  • Precise concrete placement, even with high output
  • Defining critical working areas reduces risks
  • The convenient, ergonomic one-handed control makes the work of the driver easier and ensures the height remains constant when moving the end hose in a horizontal Position
  • Optimised, semi-automatic folding and unfolding process for quicker machine readiness and greater user-friendliness
  • More stable end hose thanks to vibration damping

 

EOC – Ergonic Output Control: From zero to a hundred in one turn

  • The delivery rate of the pump is set directly with just one knob on the radio remote control
  • The electronics of the EOC then regulate the optimal engine speed for the lowest level of fuel consumption, wear and noise
  • Ergonomic one-handed control gives the machine operator a great deal of freedom of movement
  • If the boom is not moved and the pump is off, the engine decreases to idling speed, which can save up to 10 per cent fuel

 

ETS – Ergonic® Tele Service: Your advantage in the event of a service

  • Higher machine availability and lower costs
  • directly on the machine via a Service laptop
  • remotely via a modem and PC in the concrete pumping service workshop or at the Putzmeister After Sales Service

 

ESC - Ergonic® Setup Control

ESC is a system that ensures that the safety-related functions of the machine are monitored. It also allows you to work as flexibly and easily as possible within the framework of the existing directives and standards.

  • In addition to the possibility of full support, Putzmeister also offers a safe system for One-Sided Support.
  • Only certain arm positions and working areas are allowed in order to guarantee the stability of the concrete pumps in Operation.
  • It is a win-win situation in terms of safety for people who work at and with the machine and for operators because the investment is protected against possible damage

 

EMC – Ergonic® Mixer Control

Operates the mixer drum by radio remote control, including adding water and cleaning. (*for truck mixer concrete pump PUMI and truck mixer)

 

 

Ergonic® Radio Remote Control

 

Everything at a glance, everything under control

In addition to enabling convenient boom control, the radio remote control allows the machine operator to monitor and set various different parameters. The machine operator has access to up-to-date feedback and system information, such as engine speed, fluid temperature, concrete pressure, output, and pressure and volume limit at any time on the display. The strength of the radio signal and charge status of the battery are also indicated via bars.
