Construction machinery--Construction hoist

Protective Measures of construction hoist:

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.

Type specification:

1.Construction hoist of common models:

2. Construction hoist with Interver :

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.

Product details:

1. Production process: Strict material selection— blanking— inspection — welding— inspection— Blasting — inspection —Baking finished or galvanized— inspection — Finished Product

2. The product can be customized according to customers'requirements (drawing, specifications and so on).

A: The Mast section(color is variable) is made of seamless pipe.(The high quality seamless steel pipe is good verticality, anti-pressure, anti-aging, thickness and so on)

B: Main structure of cage is made of high-quality steel after bending.(The bended steel is firm, good verticality, stability. Moreover it ensure stable of the whole structure)

C: The cage is boarded up by all punched aluminum sheet.(The cage is boarded up by all punched aluminum sheet)

D:Access door interlock device protects the saftey of people and materials

E:Equiping with fall arrestor device

F:Equiping with interver in variable frequency construction elevator
