For large projects with a number of different floors and an increased number of construction hoists, using a wireless communication system improves work efficiency and allows for clear communication. The floor call system uses an advanced wireless communication mode, independent coding and decoding technology, and sound tables to stabilize frequency. Our wireless call system for construction hoist is stable, reliable, and simple to install.

Structure of the Wireless Communication System
The system includes a floor call device at every floor and a receiver display at each hoist.
The floor call device uses a 12V power supply, supplying power from the bottom floor to the top. Three cables of the floor call device connect with a bus cable while a wireless receiver device is installed in the hoist. When someone call one floor a light or sound indicator turns on, so the driver can recognize the floor and respond immediately.
Each set of wireless communication systems has independent coding and can be used between systems by changing coding.
The floor launchers and the display don't need wires to connect. The wireless receiver has a concealed antenna and is waterproof.
Continuous power ensures calls can be made anytime.
