New from HydraramPublished 25/3 at 12:12
During bauma 2019, Hydraram will present its completely renewed line of demolition equipment.
The HCC series demolition crushers, HCS series combi cutters, HSS series scrap shears, HFP series concrete pulverisers, HFP-M series concrete pulverisers with integrated magnet, HRP series rotatable concrete pulverisers and HDG series demolition and sorting grabs have all been updated. The attachments have gained more strength and Hydraram has improved the cycle times (open/close). By using hydraulic cylinders with higher working pressures, the power of the attachments has been increased by 22%, and in some cases up to 35%. Furthermore, the speed valves mounted on the cylinders are optimised so that cycle times are improved.
The HCC series features a new type of changeable penetration teeth that were already applied in the HCS series. These teeth have a better penetrating ability in concrete, which has further optimised the creaking force of the crushers. The combination of these modifications has resulted in 35% greater efficiency of the scissors. In addition to the conventional jaws which are fitted as standard in the HCC series, ‘HPJ’ jaws (high penetration jaw) have been developed, with, as the name suggests, these shorter jaws having been designed to be able to transfer even more force to the object to be demolished. Because the jaws are shorter, the leverage law (F1 · r1 = F2 · r2) is converted in favour of the force at the tip of the jaws.
The Hydraram HPJ jaws have up to 30% higher penetration force than the standard HCC jaws. Furthermore, the new HCC series can be equipped with an automatic lubrication system.
Hydraram developed the HFP series pulverisers with integrated magnet in 2018, with bauma 2019 being the first show where this magnet will be on display. This integrated magnet works on the 24V system (batteries) of the excavator, so no additional alternator is needed and is therefore easy to install. The magnet function can be switched on by the excavator's operator to easily collect the remaining concrete reinforcement steel at the construction site during crushing of the concrete. Furthermore, the magnets are equipped with a quick release system, so that the metal is immediately ejected as soon as the magnet is switched off.
The HDG series of demolition and sorting grabs has been extended to 25 models ranging from 75kg to over 14,000kg for excavators from 1t to 250t. The new HDG series is characterised by the low construction method, more powerful inner cylinders with end damping, and has only four turn / hinge points and two reinforced rotation motors for greater torque.
