Hawe Hydraulik has developed an integrated hydraulic solution for mobile machines in order to transfer the advantages of the CAN network in the control of main functions to secondary functions.
This manifold called Mick is designed for use in the concrete pump. Particularly advantageous is its use in mobile machines with several consumer groups, which work sequentially and are operated separately from each other, explained the company.
The directional valve bank type is based on the established directional spool valve type PSL according to the load-sensing principle of Hawe Hydraulik. The directional spool valve controls the flow rate load-independently and proportionally. Diverter valves are flanged directly and distribute the oil flow to the individual consumers. As a result, up to three double-acting consumers can be supplied with one valve section. Thus, for example, the product can realize the functions previously-housed in three separate control blocks (boom control, outrigger control left and right) with a single manifold.
The integrated hydraulic safety circuit ensures that the three-cylinder groups are separated from each other and prevents individual boom and support functions from being accidentally operated simultaneously, further explained the company. This block with two redundant shutdown paths thus provides the requirement for meeting safety demands in mobile machines, the company continued. Designed in the modular system by the company, this manifold offers a variety of variants and combination options. Hawe said, that with its low-pressure loss (keyword delta p), the product also represents a an energy-efficient control system, which is interesting for electrification projects in mobile machines. Automation is also supported via the CAN control of all functions, main and secondary functions.
The manifold Mick in the concrete pump will be on display at the Hawe Hydraulik booth at the Bauma exhibition 2022 in Munich, Germany, hall A3 stand 348.
