Contact Supplierwe are offering building hoist. sc200/200 building hoist
protective measures of construction elevator:
1.a master switch on the operation board: when the button closed, unexpected action to other buttons can not let cabin working.
2.anti-falling safety device (with centrifugal breaking system ): when all other protection device losing action, it can brake the cabin from falling.
3.mechanical inter-locking door: when the cabin running it can close by itself from protecting people from dropping.
4.overload calling device.
5. upper and lower travel limit: they can limit the cabin go over the top mast.
6. the top mast section have no rack in order to limit the cabin overrunning and dropping .
7.manual button: you can operate the botton to let the cabin go down when interruption of power supply .
8.emergency switch: when the cabin losing control and over-runing, you can operate the button.
adopting advanced technology, it can also be equiped with electrical overload warming device, auto landing-call equipment or autimatic leveling device according to your requirement.
a.d.o.l common electrical type: this is the common one
b.plc electrical system type.the advantages like below:
1.powerful anti-jamming performace.
2.programmable design and electromagnetic wave shielding
3.better in adaptability: adapt to different working conditions.
4.keep hoist in safe conditions by detection and recognition for machnical or electrical errors.
c.inverter electrical system type: the most advanced type and have the following advantages:
1.start / stop very stable: start in low speed and decelerate to stop. it is so stable for equipment and comfortable for passengers
2.ulta-low voltage starting: the starting voltage floating rate is within 20% (300v-450v, the normal is 380v)
3.apparent power saving: inverter type can save power about 25%-40% compare with the common type
4.mild performance: prolong the service life of the rollers, brake block, pins, mechnical driven and electricals. can decrease the friction and wear between each parts.
