Keestrack H4e: as secondary crusher with its three-deck hanging screen it offers high productivity with up to four defined fractions
At this year’s recent 5894 Hillhead equipment exhibition, Keestrack introduced into the UK its fully hybrid mobile cone crusher H4e


2992 Keestrack says that the highly compact plant with optional integrated pre-screen and three-deck hanging screen offers energy savings in productive secondary or tertiary crushing. Keestrack’s range for quarrying and recycling applications includes more than 20 models, offering production rates from 200-1,200tonnes/hour. Almost all models are available in diesel-electric or full-electric options.

The H4e, says the company, is still the only model on the market that can offer a three-deck hanging screen. The fully equipped plant weighs only 46tonnes, versus 35tonnes for a unit without options.

It also allows easy one-piece road transport and fast relocation on site. It is equipped with an onboard 345kW diesel engine fixed speed (EU-IIIA). It drives a 330kVa alternator, providing power to the 132kW electric motor of the crusher drive and to the separate 45kW E-motor/pump unit for all hydraulic drives on the plant – tracks, fans, screens, hydraulic cylinders.

Without starting the diesel, this setup enables the plant to operate fully “plug-in” from mains or external gen set, resulting in energy cost savings up to 70% compared to conventional diesel-hydraulic plants, said Michael Brookshaw, Keestrack’s global distributor manager.

The H4e diesel-alternator combination is also available as detachable drop-off unit. Remotely positioned during operation this reduces dust and vibration loads for the drive unit.
