Drive 700 Estru (Pic. 1) is an electro-hydraulic motor pump unit fitted with bi-directional gate locking device, suitable for single applications when the gate involved is not particularly large and only one actuator Mec 800 Special is required. Being quite compact, this unit can be installed either close to the gate post or recessed in a brick pier by means of a galvanized enclosure which can be supplied on request. Very precise component parts and the special oil which is used in the hydraulic circuit make it extremely reliable. It is made up of a valve block, oil reservoir, top cover and a lockable door which gives access to the electric cable and all the electrical connections. A sight glass indicates oil level and a funnel is incorporated for filling. Adjustable pressure valves can be set to the right amount of force required to safely operate a gate open and close, while a release valve can override the locking device and allows manual operation of the system in an emergency situation or power failure. Drive 700 Estru can work to its utmost provided that is respected the recommended duty cycle, that is “S3” intermittent service.

700/80 VENTIL

CYCLE 3 - INTERMITTENT

Mec 700/80 Ventil (Pic. 2) is a very strong motor pump unit. As the above described unit it is fitted with bi-directional gate locking device, but the motor is air cooled and the oil reservoir has a greater capacity. The adjustable pressure valves and the release valve are easy to reach for setting operations. The special oil ensures proper functioning within a considerably wide range of temperature from

-20°C to +80°C. An enclosure is available on request to protect the unit from weather conditions or accidents. The enclosure is designed to provide enough ventilation and is fitted with a lockable door for security reasons. It can be fixed close to the gate post or recessed where a brick pier exists. The great advantage of this unit is the possibility of extra oil reservoir to operate two actuators Mec 800 Special per gate, with very large and heavy gates. Designed for heavy duty applications, S3 duty cycle, motor direction easy to reverse.

It is important that the gate hinges are close to the inside edge of the gate post.

Instructions to follow to fit MEC 800 to a double swinging gate. It is recommended to respect all the steps described in this manual to achieve a perfectly working installation of the system.

Before installing MEC 800 special it is important to check the structure of the gate and make sure that it is adequate to take the actuator, there must be no problems at all with the gate frame, which must be strong and robust to be electrically operated. It is recommended to strengthen and fix all the parts that look weak, or worn out, eliminate any friction of the gate against the gate post or pavement (check the hinges, the gate must be very smooth). The actuator is mounted to the gate by specially designed plates, one to the gate and one to the gate post (Pic. 5). MEC 800 is very strong and powerful. The thrust power that it can develop is high and safe. The motor pump unit is fitted with adjustable pressure valves. It is entirely made of steel and pressure cast aluminium, the temperature range it can safely bear is -20°C +80°C (Pic. 7).

Installation: remove the anodized aluminium cover by unscrewing the two hexagonal nuts in the front cover plug (see pic. 4). Pull the cover horizontally and lay bare the cylinder, piston shaft and ball bearing front fixing. The fitting of the rear fixing plate to the gate post or brick pier can be either by welding, with the use of a square plate as in the picture, or by embedding. Anchor plates are to be used to secure the actuator plate into the concrete setting. Fixing geometry, ie. distances between hinge centre line of the gate and back fixing centre line of the actuator, are provided in pictures 5 and 6, on page 4, and pictures 21 to 23 on page 9. These are for long stroke braking actuators. Follow which applies.

Make sure that the distances A and B are A = 140 mm and B = 130 mm respectively measured from the gate hinge centre line to back fixing centre line. This ensures smooth and even movements of the gate. Distance D is 80 mm from the centre line of the hole in the front fixing ball to the centre line of the gate plate (pic. 6). (Distances to be referred to only with MEC 800 actuators, 280 mm stroke).

Before the square reinforcement plate is finally fixed to the gate, make some tests, the ball bearing head fully screwed in, allowing the piston to reach the very limit of the permitted stroke. Operate the gate manually to open and close. Try a second time with aluminium protection cover fitted. Once satisfied that the fixing distances are all right, remove the cover and weld the plate fully as shown in pictures 5 and 8.

Fix the front fixing plates and swing the actuator on to it, the piston shaft must be all out and the thread of ball bearing head all in, ie. not visible on the outside. The gate fully closed against its ground stop. A spirit level will tell if the actuator is perfectly straight (Pic. 5 - 8).

After completing the fixing operations of the plates, unscrew the ball bearing head 5 or 6 mm approximately and tighten the nut to lock it in the correct position. This ensures the correct position of the gate on the closed gate stop (Pic. 9)
