THREE VIBRODRIVERS RANGES
The best range for your application depends on the proximity to the existing sensitive structures. If the piling works are done in a sensitive area (city centre), and you wish to control the vibration and limit the particle velocity (mm/s), PTC’s vibrodrivers with Variable Moment (HFV & HV ranges) are the best choice. For contractors working on other structures, standard vibrodriver with a fixed eccentric moment (HD) are the best fit.
Soil and pile properties (height, weight, and pile type) are key to determine what eccentric moment and centrifugal force is required to drive the pile to the desired depth.
URBAN RANGE: HFV
High frequency and Variable Moment technology
The HFV range (high frequency) allows to adjust the amplitude at any time, thus it is highly recommended for sensitive areas: city centres, or near sensitive existing structures (bridges, railways, old houses, pipelines, etc.). The HFV vibrodrivers are suitable for telescopic boom cranes thanks to their resonance-free start-up and stop. The VIBMASTER® monitoring system is highly recommended.
SUBURBAN RANGE: HV
Standard frequency and Variable Moment technology
The HV range offers the comfort and the advantages of the Variable Moment technology while working at standard frequency. Therefore, it requires less powerful power packs than high frequency vibrodrivers. These vibrodrivers are suitable for telescopic cranes thanks to their resonance-free start-up and stop. The VIBMASTER® monitoring system can take advantage of this range and is greatly recommended.
PTC HV vibrodrivers do not need high revolution speed to work effectively. They harness the full potential of the H / HD vibrodrivers with all the technicity of the Variable Moment technology.
HEAVY-DUTY RANGE: HD
Standard frequency and fixed eccentric moment
The most famous range of heavy-duty vibrodrivers in the world, known for their longevity guarantee. This range is designed with hard-wearing materials and is manufactured for the strongest mechanical resistance. In spite of all this robustness, H / HD vibrodrivers have high vibration-absoption capacities to get steady vibrations in order to protect boom cranes.
This range adapts well to sheet piles applications and driving of casings of up to 100 tons.
PTC offers multi-purpose power packs that feature state-of-the-art automation, a screen for work ergonomics and easy transfer from one machine to another, as well as an open loop circuit, which allows the power pack to supply power to multiple equipment: vibrodrivers, hydraulic hammers, vibrolances, drills and more.
