MB-W Pneumatic Bus Door Pump for Coach/Tourist Bus Consists of:
1. Arm asm(including arms, door pillar asm, upr-bracket, tie rod, angular connective irons, door/frame wedges etc.)
2. Pneumatic door mechansim and relevant control units(e.g. emergency valve, solenoid valve, switch)
Main technical specification:
| Working voltage | 12V, 24V |
| Air pressure | 0.4~0.8Mpa |
| Swing direction | Left/Right |
| Max. swing angle | 140° |
| Max. lift height | 20mm(at swing angle 140°) |
| Load capacity | No less than 1000N(at min. load door weight) |
| Endurance | 1000000 times |
Performance and characteristics:
| Overload protection (i.e. anti pinch) | If the door encounters resistance greater than 300N during operation, it will open immediately to ensure that passengers won't be pinched. |
| Self locking | After the door is lifted, the piston of the cylinder will be locked. When the speed is greater than 5km/h, the speed measuring mechanism will automatically cut off the power supply of the door opening pump and will never open the door due to misoperation when the bus is running. |
| Safety | When the product loses control in an emergency, the door can be opened and closed easily by hand as long as the handle of the emergency switch is placed in the "off" position. |
| Structural form | Front mounted (Swing to the front when the door is opened). Rear mounted (Swing towards the rear when the door is opened). |
