●
This Hydraulic Installation Clamp HVZ-ECO was developed to meet the need of builders for a device to mechanically
install a wide range of pavers which are delivered to the site in ready-to-install formation. The HVZ-ECO may be used in
connection with any carrier (mini-excavator, hydraulic excavator, wheel loader) .
●
To operate the hydraulic installation clamp 2 separate hydraulic circuits are required on the carrier (excavator).
●
With the device (HVZ-ECO) it is possible to handle one layer of pavers. Do not exceed the carrying capacity/working
load limit (WLL) and the maximum width of the device HVZ-ECO.
●
Only pavers in good quality are allowed for laying. Pavers with „feet, bellies and blind spacers" are not allowed",
because the complete bricklayer could fall out of the device.
The device is equipped with:
Requirements for hydraulic operation:
(Operating hydraulics of the carrier)
HVZ-ECO:
– Volumetric flow (l/min), usable min. 25, optimal 35 – 40, max. 80
– Working pressure (bar), usable min. 180, optimal 200, max. 320
– Backflow pressure: max. 10 bar
Minimum excavator operating weight:
– HVZ-ECO from approx. 2,3 t
(Operating weight may vary depending on excavator type and form. No binding specifications: must be co-
ordinated in the individual case.)
