Operator for sliding gates type NGS-RS with limit switch system

NGS-RS is a compact assembly entity with limited dimensions. The worm-wheel gear-box is equipped with an infinitely variable torque limiter and an unlock system. The safety torque limiter is built between motor and gear-box. This means that when the motor is stopped the irreversible system of the gearbox locks the gate so that normally no additional locks are required.

Due to the unlock system it is possible to open the gate manually. The motor can be mounted horizontal or vertical. Standard voltage 3-phase 230/400 V. motor with thermal protection in the coil (special voltage at options).

The limit switch
On the reduction is a box mounted with limit switch ES10, this can be connected with a separate controller which can be chosen out of the LST/WST range. The limit circuit then consists of a potential-free limit switch, a control current limit switch for determining the end positions and a safety switch for each direction of rotation.

Operator for swinging gates type OPTIMUS

Operator for swinging gates protected against the most conditions. Due to the robust method of construction it is extremely reliable and especially suitable for industrial use. A noiseless self-locking worm-wheel gearbox with integrated infinitely variable torque limiter. The worm-wheel of special bronze and worm are equipped with ball bearings and runs in oil.

The self-locking of the operator and the stretched position of the swing arm mean that the gate is mechanically locked in the closed position. An additional gate lock is not necessary. The quick release enables manual emergency operation. Furthermore, this operator is equipped with a three-phase motor and magnetic limit switches.

By using a quick unlocking system the gates can be opened manually whereby the motor limit switch setting remains unchanged.

The separate control boxes can be chosen from the WST/AST series.
