Hydraulic add-on vibrators are mounted to the stick of a hydraulic excavator instead of the bucket and are connected to the hydraulic system for driving and extracting trench sheets, sheet piles, H-piles or steel pipes up to a length of 7 m (depending on the stick configuration)
ABI hydraulic add-on auger drives are mounted to the stick of an excavator of sufficient weight and power and connected to the hydraulic system of the base machine for a wide range of drilling applications such as soil release drilling, well points, deep wells, small CFA piles, soil mixing and much more. In combination with the ABI casing twister fully cased CFA piles can be made at very reasonable cost. The DBA series of auger drives can be delivered with a concreting swivel for pumping concret
The MC-E line has been designed to operate in restricted access working spaces, where particular soil configuration, bearing capacity and limited space make it impossible to use a crawler mounted drilling rig: Docks, road edges, rock walls, slopes, etc. The hydraulic drilling rigs of the MC-E line are installed at the end of the excavator booms. Using the excavator boom movements combined with a slewing ring or with the Comacchio patented mast joint support, these machines can reach an extreme
Marini drill mast attachments are available for a wide range of hydraulic excavators from 2 to 30 ton operating weight and can be equipped with rotary heads or drifters (top hammers) mainly for the installation of self-drilling anchors and micropiles. Key advantages of drill mast attachments are that standard excavators can be transferred to high-performance drill rigs and the extended working range in length of height which crawler drill rigs can't reach.
Simex TF cutter heads mounted to the boom stick of an hydraulic excavator are ideal for trenching, profiling rock and cement walls, tunneling, quarrying, demolition, dredging, finishing operations and underwater works. They are highly effective where conventional excavation systems are too weak and percussion systems have little effect. Their quiet operation allows them to be put to work near sensitive areas (residential zones, hospitals, schools, bridges and infrastructure).
The excavator lifts the pile breaker over the pile and at first stage a complete horizontal fracture is made. The chisels penetrate in horizontal direction up to the re-bars for about 25 seconds to make the fracture. At second stage the chisels penetrate further (usually 25-40 mm) and due to the shape of the chisels and the reaction forces by the rebars, the concrete will break in pieces and can easily be lifted off the pile.
The revolutionary Omnicut Rocksaws in single or multi-blade version combine the hardness of diamonds with the robustness of tungsten carbide. They cut up to 10 times faster than tungsten carbide blades and are suitable for all materials, from soft rock to steel-reinforced concrete and for hard rock up to 400 MPa. Omnicut Rocksaws are available for excavators from 1-100 ton and with blade diameters up to 4000 mm.
Tungsten carbide saws are ideal for materials not harder than 40 MPa and where is no cooling water available. They are better suited for soft materials than diamond saws, operators need less skill to achieve good results and worn picks can be easily replaced. Several models are available for excavators from 12-90 tons and blade diameters up to 3000 mm.
Our hydraulic telescopic excavator arms can be mounted to the mono boom of any hydraulic excavator of sufficient operating weight (33-45 ton) and hydraulic power. The Telearms are operated by one large hydraulic cylinder offering excellent performance up to an excavation depth of 23 m (with extension) and manufactured according to European standards for trouble-free operation with little cost of repairs and maintenance. Main application is the excavation of deep manholes and shafts for jacking
