Product Description
           Building Mmaintenance Unit Hydraulic System Bmu

Traversing trolley
The lower trolley is a tubular structure with hot dip galvanized protection.
The trolley and the turret are connected by a powered slewing ring.
For a trolley running on concrete trackway and with a 2500 mm turret, the rear wheels are mounted on an articulated spreader beam to ensure an even spread of the load on each of the four roller frames.
Hydraulic system
- Depending upon the configuration of the machine, the hydraulic unit supplies :
a) the motor for slewing the turret
b) a ram which operates the extension/retraction of the telescopic jib or the inclination of the jib
c) a ram which operates the extension/retraction of the telescopic mast .
- the power supply cable for connecting the trolley to the power points. This cable is stored on a reeler under the trolley.
- an electrical box with a remote control for the trolley

These types of machine provide optimum access to every part of the building. The spreader bar at the end of the jib enables the cradle to rotate to be parallel to the building. This type of machine offers a high level of comfort to operators.
Each case will be individually studied by NJFRD design office in cooperation with the architect to meet the exact requirements:
- length of jib to cover all the glazed areas of the building
- lifting height to cover the glazed areas

Safety systems for emergency
1cradle overload safety deviceThe BMU equipment will be stopping the service, if the cradle bear the load more than the safety load.
2cradle upper safety limitAs soon as the detection switch detect that the cradle lift upper end and alarm lamp lighted, the lifting function of cradle was failing.
3cradle FINAL upper safety limitAs soon as cradle upper safety limit was failing, the cradle FINAL upper safety limit will be enabled in order to protect the staff and equipment and property.
4Cradle obstacle detectorAs soon as lowering cradle discover the obstacle(ex. Opening window), the warning signal was send and the lowering function of cradle was failing.
5lower anti-collision barBuffering the cradle and curtain wall may led side impact.
6slack wire rope safety deviceDetecting the four suspension steel ropes, if one of the steel ropes was breaking, the equipment warn and start the safety devic.
7Anti-Roll BarFour Anti-Roll Devices, preventing the equipment was tipping.
8emergency stopOn urgency circumstance, pressed emergency stop switch and the equipment will be stop working and start the safety protection.
9power-off protectionIf the power is breaking suddenly, equipment will start safety protection. Then the manual release system is to be provided to safely lower the cradle to the ground in the enent of a power failure. When the power is supplied suddenly, the BMU can not start for avoiding the unexpected accident.
10lightning protectionSpecial wire link the lightning system of the building, prevent to make the accident.
11Power cable Anti break protectionProtect the Power cable can not break when the equipment is traversing.
12phase order safety deviceTo prevent the Power cable is opposite phase,Lack of one phase ,Leakage phase,overvoltage,under voltage.
13warningAs sonn as the limit switch was started or fault occurs, the warning will give you a hint.
14Text monitorwhen the limit switch was started or fault occurs, Text monitor can show you the fault massage in order to hadle it.
15Limited weight index tagThe index tag was sticked in the front of the cradle
