Designed to satisfy the specific demands of rental fleet operators, the 370 kg 777, is designed for optimum carrier compatibility and installation flexibility. It features a pivoting hose connecting block and reversible manifold that allows for both right or left-hand hose connections, in addition to it's ability to accept a wide range of oil flows and pressures.
The Flange mounting mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
The twin-handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.
Single lower tool bushing
The single lower tool bushing, replaces the need for an upper and lower tool bushing, whilst being field replacable. This makes for faster and easier field service.
Membrane type accumulator
Membrane-type accumulator eliminates nitrogen leakages, ensuring maximum piston acceleration and removing the need for time-consuming recharging.
- CBE+ (Constant blow energy plus)
The light weight design allows the use of smaller carriers without compromising the stability of the carrier.
No tie rods
Fast and easy to service with no particular tooling needed for it
Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
Hydraulic excavators have largely replaced cranes with wrecking balls, enabling demolition to be carried out in a much more controlled and efficient manner.
