  • Master of steel

    5RZ46 1The SUPERLIGHT concrete pumps have been thoroughly designed by our technical office S-Design with special five (5) and six (6) articulated boom, with the mixed “RZ” folding configuration that allows excellent movement performance.

    The equipment has been designed both for assembly on standard trucks 4 and 5-axles due to the extremely contained total weight, that offers:

    5RZ46 < 32 t: exemption of road circulation permits thanks to the underweight legal

    6RZ56 < 41 t: underweight compared with the potential of the chassis

    6RZ60 < 46,5 t: underweight compared with the potential of the chassis

    The use of high-strength steels and the particularity of our design allow us to create the lightest boom structures with the advantage of using more contained stabilizations to the benefit of operations on construction sites presenting difficulties in stabilization spaces, and achieve an excellent cost-performance ratio without the use of composite materials.

    5RZ46 2The concrete pumps 5RZ46, 6RZ56 and 6RZ60 SUPERLIGHT complete the SERMAC’s range of pumps and open new advantages to our customers.
  • Electronic stability control system SCS

    trdThe european regulations UNI EN 12001: 2012 provides for the control of the stability of the machine with total or partial opening of the stabilization.

    In compliance with the regulations, SERMAC has designed and implemented the stability control system SCS (Sermac Control Stability) in the BASIC and ADVANCED versions capable of significantly increasing the degree of safety of the machines and their use.

    The SCS - BASIC model is applied as standard on the whole range of truck-mounted concrete pumps and mixer pumps. The system provides for the complete opening of the stabilizers to safely move the distribution boom.

    The SCS - ADVANCED model is available as an optional and allow to work in total safety even with the partial stabilization opening. Thanks to the constant control of the overturning moment, the system constantly checks the position of the boom and the value of the loads on the stabilizing cylinders. The operator can therefore work in complete safety with the stabilizers partially open in the maximum extension of the boom.

    On the equipment, in position with the controls, there are two displays that allow to check the correct opening of the machine and the value of the loads on the stabilizing cylinders. Furthermore, a display on the remote control allow to view the exact position of the boom and the permitted work area.

  • MeDUSA

    medusa 1121The new electrical system developed by SERMAC uses CAN-Bus communication technology to manage the machine commands.

    This system allows simplified communication between the actuators mounted on the machine using a single electrical cable and optimizing the number of components used within the system which, unlike the classic centralized analog system, each peripheral must be connected with its own cable to the main electrical panel.

    The new CAN-Bus system is called MeDUSA from the union of two technologies. The "me" as a direct interface to the operator, oriented towards the simplified user experience of the electronics that controls all the functions on the machine, and the "medusa - jellyfish" as a control system unstructured by a series of electronic control units connected to each other via the CAN-Bus line like the tentacles of a jellyfish.

    In addition to the above, the real added value is represented by the integrated diagnostic system that allows easier maintenance of the equipment, both in the ordinary and extraordinary phase, thanks to the simple interface made available to the operator.

    The MeDUSA system allows a couple of advantages:
    • Electric system easy to install and use with considerably simplified connections
    • Absence of a main electrical panel
    • Possibility of managing the new components / options in a more flexible way
    • Ability to view various information useful to the operator for using the pump on the machine display
    • An advanced diagnostics that allows a check of all the peripherals / actuators during the start-up phase in order to be sure of correct machine operation
    • Presence of the color graphic display for over 4 "directly on the transmitter of the radio control to have direct contact between the operator and the information arriving from the machine
