CHC-II

The CHC-II is the newest generation Computer Hoist Control following the tradition set by our original CHC that helped revolutionize stage lighting over the past two decades. The same quality and reliabilty experienced on thousands of shows continue into the CHC-II.

The CHC-II operates on a pc platform with 3.5” fl oppy disk data backup. Users are able to preset complex hoist cues in a menu-driven program to operate 32 chain motors singularly or in coordinated movement. An entire show can be programmed in manual mode to create and link cues to create repeating patterns, timed pauses or running strings of cues in succession.

Safety is at the core of the program. Our unique watchdog feature shuts down the system in case of a control malfunction. A hoist group will shut down if any hoist in the group becomes stuck or malfunctions. Soft limits can be set to limit running within a safety zone.

Owners of CHC-32 packages can still use their existing accessories. The CHC-II uses the same industry-standard hoist-mounted sensors used in thousands of motors worldwide since we developed them in 1984. The same multicables, 4-pin xlr sensor cabling and breakouts are also compatible with the new control. Display uses any standard fl at panel display and standard pc keyboard. The chassis fits into any standard road case. All the components are sold individually.

Relay control interface between the hoists and the CHC-II is necessary. Our CS models or the TR-8000 package will provide this interface. We can provide inverter packages to work with your existing chain hoists.

TOUCHSCREEN DISPLAY CONTROL

Operation of a large number of chain motors is made manageable using one of our touchscreen displays. TDC enables manual hoist selection and running in the same way as a conventional toggle switch operated run station, but requires a fraction of the cabling.
Touchscreen operation enables features unavailable with conventional remotes, such as the ability to create and name hoist groups. Hoist encoders are not required for this type of operation. Position feedback, cueing and variable speed control are enhanced features requiring our quadrature encoders in the chain motor.
Variable speed control can be performed using hoists with integrated inverters or standard chain hoists with external inverters. TDC can be used to operate any ac or dc winch.
Load monitoring, using our load cells, is offered. High and low weight limits can be set. Readouts show individual and total weight feedback with peak load tracking.
An array of touchscreen displays are offered to suit the user’s needs and budget. All operator stations have a mushroom head emergency stop button and a momentary run button. On/off keyswitch can be provided.
The entire package can be configured for permanent installation or for portable use. The TDC can be handheld, rack mounted, be in a tabletop console or mounted on a conduit-fed enclosure. Control units have C/UL 508A listing.
