THE LATEST point machine from Alcatel is designed to be integrated into a sleeper, allowing a greater degree of pre-assembly and reduced installation time. The L826H is an electro-hydraulic unit with variable stroke, making it virtually maintenance-free. It is currently on test with German Railway on pointwork supplied by Butzbacher Weichenbau, and should be available early next year.
A waterproof electric motor drives the hydraulic pumps via a coupling to create a closed oil circuit. The reversible radial-piston pump and hydraulic cylinders drive through a full rotational angle each time the point is changed, ensuring a constant change time. An over-centre mechanical locking arm compensates for any excess movement and ensures a firm closure. The unit can be hand-cranked if necessary, and will also be available in a trailable version.
