0-60M 2 ton VFD Rack Temporary Construction Elevators Hoist Lift 


Product Overview 

The hoist drive devices and cages are generic and interchangeable because of the truly modular design.

Variable Frequency Drive make the elevator start smoothly with low current and less wear and tear.  

Intelligent control System with fault detect, display and alarm, and automatic cage landing/stop and floor selection.

It is certified TUV according to European Regulation EN 12159:2012, EN 60204-1:2006/A1:2009.  

Features of the hoist 

* Energy-saving gear reducers. 

* Racks are at the center of mast to reduce partial load torque.

* Non-eccentric rollers of easy installation.

* A full steel plate welded one time to complete to make cage roof,and edges totally welded.

* Cage frame steel is bigger and stronger. 

* Unique flap door as loading/unloading ramp. 

* Be equipped with a frequency control unit (FC), with closed-loop.  

* Easy access to electrical panels.  

* Certified safety brake system.

Hoist Safety - Limit Switches 

Hoist limit switches - There are limit switch touch plates on the top and bottom of the mast. When they hit the limit switches on the cage, the cage will stop automatically. 

Hoist emergency limit switch  - Once the cage exceed the position in case of fault of upper and lower limit switches, the three-phase emergency limit switch will touch the emergency touch plate on the mast and cut off of power supply.

Builders Elevator SAJ type Safety Device - Centrifugal Brake 

SAJ type Safety Device (centrifugal brake) is an extremely important safety device for rack and pinion construction hoist. Its

principle is to prevent the cage from running down over speed, effectively preventing and eliminating the accident of cage

falling.

It is the most ideal device for construction elevator anti-falling safety, which is rigorous in design, reasonable in structure, fine in production, reliable in quality and stable in performance.

What is Construction Elevator Drive Device (Drive System)

The drive device is mainly composed of the drive frame, two or three motors, electromagnetic brake, elastic coupling, worm reducer or cylindrical gear reducer, and drive pinion. It connects to top of cage rigidly or elastically. The drive pinion is fixed to the output shaft of reducer by the spline, and is aligned and meshed with the racks on mast.

How does the Construction Lifts Drive Device work?

Driven by the motors, the pinions drive the Drive Device on the racks to bring the cage and its load to go up and down or stop along the mast.
