Electrohydraulic solutions for telescopic handlers

 

HYDAC has on offer a wide variety of components, systems and services for telescopic handlers, which are by no means easy to handle.

This is because telescopic handlers must cope with various operating modes and situations: although they need to be fast and agile, they also need to load and transport goods safely and carefully.

Loading and manoeuvring in confined spaces is also nerve-wracking for the user: the load must not only be gripped and held securely, but also lifted and put back down with precision.

 

HYDAC solutions

HYDAC supplies hydraulics with appropriately sensitive reactions that implement all control commands from an in-house electric control with fast response times.

Operational safety and user safety are a top priority and realised in accordance with functional safety standards.

This is partly achieved through use of hydraulic controls such as boom suspension and telescopic arm control, which prevent overload and tipping.

For rapid transport, the ‘Ride Control’ system is used to secure the load and provide safe suspension for the vehicle and its telescopic arm.

For all basic functions, whether pump supply, cooling, filtration, steering, braking, suspension, working hydraulics or electronics, HYDAC has a solution at hand.

 

Functional safety

HYDAC provides:

  • Certified controllers and I/O modules
  • Sensors and valves with enhanced functional safety
  • Support from risk analysis to certified machine function

 

Filtration and tank systems for telescopic handlers

In addition to classic breather filters, inline filters, return line filters and return line suction filters, HYDAC’s extensive range of filters includes special return line filters for optimised air removal in multiple variants (RFB, RFT, RKB, RKT).

The filters’ special geometry and innovative technology ensure that oil flow is well distributed in the tank.

This enables high air removal and a reduction in the hydraulic tank size.

Enormous cost savings are therefore possible for the owner and OEM in terms of reduced oil and material used.

HYDAC supports customers and increases functional system safety with innovative filter media Stat-Free and Stat-X in the fight against electrostatic discharges.

For smooth operation in diesel filtration, HYDAC recommends the Diesel PreCare filter system range.

Smart additional functions, such as an integrated electric pump or filter medium (Biomicron), protect against contamination (diesel bug) in the filter, ensure safe machine operation and low service costs.

The smart sensor Virtual Fluid Lab (VFL) makes it possible to determine the filter’s remaining service life so that filters can be changed only as needed.

This enables filtration capacity to be exploited fully. The benefits of this are maximised service intervals, predictable service, and increased availability.

 

Diesel fuel pump kit

The diesel fuel pump kit enables the fuel tank on the vehicle to be filled independently of stationary tank systems.

  • Certified operating voltage: 12 / 24V DC
  • Flow rate: 5 – 50l/min
  • Integrated temperature switch
  • Completely sealed nonreturn valve, leak-tight

 

Steering

HYDAC electrohydraulic primary and auxiliary steering systems allow various types of steering to be realised in telescopic handlers.

In addition to standard driving modes, other possibilities include four-wheel drive and crab steering.

In combination with the hydraulic steering systems on the front axle, electrohydraulic superimposed steering systems and auxiliary steering systems for the rear axles are possible.

The steering valve module from the EHZ series has a modular structure and can be used in two or multi-axle self-propelled vehicles.

Different inlet modules enable connection to all types of hydraulic systems.

The proportional valves used are specially ∆p optimised for use in steering systems.

The basic module is designed for one steering axle and a second module for a two-axle vehicle.

Other modules can be added for freewheeling, locking, or centring steering cylinders. Shock valve modules are also available to protect the steering cylinders against external factors.

 

Conditioning of hydraulic, lubrication and diesel fuels

Dust, water and internal wear lead to increased valve and pump failures, leakage, and loss of efficiency.

HYDAC supplies the device technology for safe fluid handling.

Measures to remove solid particle contamination, water and gases keep the machine hydraulics in good condition, increase efficiency and reduce costs for spare parts.

On offer are mobile and stationary oil conditioning devices for initial start-up rinsing, filling and transfer filtration, filling and venting of hydrostatic drives.
