FEATURES TO NOTE IN A GRAB EQUIPMENT
While deciding on which grab equipment to employ on site, following are a few features to take note of which shall help in differeciating grab equipments with similar technical specifications.
Hydraulic Cutter
To capture the slight tilts of grab inside trench
Angle sensors to capture the slight tilts of grab inside trench | Winch synchronization to bring stability to the grab during the grab hoisting and releasing process | On screen grab display to visualize the grab position and construction curve in real time which enhances the grab position adjusting efficiency, and helps in achieving verticality. |
---|---|---|
A lower centre of gravity that imparts increased stability to the equipment. | Alarm lamps to inform others whenever the equipment is working or swinging, avoiding accidents. | Camera on rope drum to monitor rope winding condition and help operator stop as soon as any disordering or slack is observed. |
Multi-layered steel wire wrapped hydraulic hoses to withstand high pressure and avoid explosion. | Anti-twist and wear resisting wire rope required to ensure smooth working of equipment. | Winch derricking for the grab helps increasing the derricking range, easy operation and high construction safety. |
Lighter truss mast to shift centre of gravity backwards and effectively absorb shock during construction. | Sufficient carrier working radius to prevent trench collapse by ensuring that the equipment is able to work at a safe distance from the trench. | Hose drums designed to ensure smooth operation of hose pipes |
