Point Machine

SAM SAM produce both electric and hydraulic motor driven point machines. There are five different models for these products : NS, NS-AM, NS-AM-L, YB210 and HPS. The machine can be separately designed and tailored to meet the special requirement by the customers.SAM SAM provides wide trailing stroke range from 185mm to 210mm for heavy and light rail line. A sensor is attached on the stock rail to detect the close adhesion of tongue rail to stock rail.

Features:

?NS : NS Type Point Machine is an electric motor driven point machine that has been verified its high reliability by long years of successful operation in railway and subway. The machine consists of electric motor as a power source, magnetic clutch and reduction gears as a medium of conveying powers, and thrusting bar as a device to change the rotational movement to linear movement of the power. NS type point machine use mechanical frictional clutch, which requires seasonal adjustment of the spring force due to the temperature dependent operating mechanism.

?NS-AM : NS-AM Type Point machine replaced the mechanical clutch of the NS Type Point machine with electromagnetic clutch with magnetic brake system. The magnet clutch requires no seasonal adjustment and no harmful impact at the moment of closing position by inertia force, which provides constant thrusting force and low operating cost.

?NS-AM-L : NS-AM-L Type Point Machine has been designed by the specific requirement of a customers from Iron & Steel making company in Japan. This Point machine adds up Signal light Unit to the existing NS-AM Type Point machine. This Point Machine is to replace the old YB Type without changing existing Signal Control System.

?YB210 : YB 210 Type Point Machine is a semi-automatic point machine that is handled by train operator with tappet switch and lever switch mounted near the railways. The machine is used mainly for the location where the frequent switching of the turnout point is required. Major consumer of this type of point machine is Steel & Iron Making Company is being replace with the HPS that SAM SAM has developed.

?HPS : This HPS Type is Hydraulically operated Point Machine that has been engineered and designed by SAM SAM. This Point machine produce maximum thrusting force up to 1,000kgf compared to 400kgf by the electromotive point machine. The machine is light weight and no left & right version so that restriction on installation location and cost are drastically reduced and even applicable to confined space like subway. The control unit is water proof that prevents any breakdown of the system caused by the water leakage in the raining season. This point machine has been tested and verified its successful operation in Korea railways. This point machine drastically reduce the installation and maintenance cost.
