MIB 10/20 Gates

Technical Description

The combination of our proven and reliable electric motor with a lever system represents a simple and extremely reliable drive solution. It permits short opening and closing durations without the barrier boom bouncing in the end positions. The lever system locks the barrier boom at both end positions. In the event of a power failure, it can still be moved easily by hand. The complete drive system is attached to the barrier housing as a single unit, and can easily be removed from the housing by removing the mounting screws. A built-in spring mechanism provides a precise counterbalance for the barrier boom. The springs are factory set to correspond with the boom length prior to delivery. If necessary, the springs can be easily reset on site during assembly. It is also a simple matter to change the configuration on site from right-hand to left-hand.

The two barriers MIB 10 and MIB 20, ideal for toll road and other super high speed applications, differ in the type of motor drive they are fitted with. In the end positions, the motor remains with voltage applied but at reduced power. This power is dissipated in the form of heat, which prevents the occurrence of condensation and corrosion. This guarantees consistent opening and closing times, even in cold climatic conditions.

Operating at 0.6s opening/closing times, the heart of the barrier is the combination of the brushless maintenance free direct current motor and intelligent controller. This combination, developed especially for this application, represents a substantial technological leap forward due to its flexible acceleration and deceleration and its independently adjustable opening and closing times. This further optimizes the movements achieving considerable service life with long maintenance-free intervals. Hall sensors integrated into the motor provide precise data regarding the position of the barrier boom at any particular instant, and they also provide the control system with a way of verifying the optimum acceleration and braking characteristics. By calculating the exact position of the boom, it is possible to make feedback directly available in any position in the form of zero potential signals. This removes the need for mechanical limit switches which are prone to wear and tear.

Operating at 0.9s opening/closing times, the heart of this barrier is the special AC torque motor. The features of this motor are its long service life, freedom from maintenance, and the fact that it is possible to stall it in any position without risk of damage. Imprecise friction clutches and limit switches are not necessary. The position sensor sends precise data concerning the position of the barrier boom to the control unit. The optimum brake position of the barrier boom is always guaranteed as a result of the controller developed by Magnetic. The controller is equipped with built-in dual channel loop detectors and self-learning software preventing any subsequent bounce of the barrier boom. The barrier is factory wired and ready to connect, tested and supplied with mounting accessories.

The housing is manufactured from 14 gauge zinc plated sheet steel on to a base frame of stainless steel, then phosphate and powder coat finished for maximum protection against corrosion. Controllers are mounted onto a removable zinc plated sheet steel panel. All of the components within the barrier housing are readily accessible through the maintenance door and removable top cover. The standard color for the MIB 10 housing is RAL 2000 orange while the MIB 20 is available in RAL 2000 orange, RAL 9010 white and RAL 1028 yellow as standard. Other colors are available for an additional charge.
