These systems are not provided with an engine room, as all electrical and mechanical equipment are mounted inside the hoistway, providing more commercial space to the building. Generally, the control panel is applied to the last upper level adjacent to the elevator door.
The ESG system is the life that offers considerable advantages:
The rigid structure and excellent acoustic insulation of Raver cabins, which are always coated externally with sound-absorbing material, ensures a smooth, straight and silent ride.
The hydraulic lift uses technology established over time, which makes it a very reliable system, easy to install and easy to maintain.
The principle of operation is very simple: the cabin is laid on a metal arch connected in turn to a piston that intakes mineral oil under pressure with a valve adjusting flow. Going up, the hydraulic pump pushes the liquid in the piston causing the ascent of the cabin, while the descent uses gravity.
The absence of a counterweight and the reduced overall dimensions of the mechanical parts offer the advantage of better optimising the compartment space available for the cabin, creating larger tread surfaces.
The use of special metal cabinets is called for, and in addition to the hydraulic control unit they contain the control panel and the electrical energy distribution switchboard.
With this type of system, large hoists-lifts can be made for capacities up to 12000kg for assembling cars or even trucks, a field that RAVER has many years of experience in.
The hydraulic system is the perfect solution for buildings with a few levels and limited traffic.
Safety and attention to detail are the basis of the construction principles of RAVER lifts.
