2907TV Silver Service®, 7007TV, 9007TV Hercules®
Models 2907-TV, 7007-TV, and 9007-TV ranging in horsepower from 1/2 to 2, are the premium lift machines of the ADC line. Equipped with electronic frequency drives, these machines are the most versatile in the ADC line. Designed for lift applications, these machines offer a multitude of parameters that can be programmed in the field to meet a variety of applications. Parameters such as run speed, maximum obtainable speed, minimum obtainable speed, acceleration ramp time and deceleration ramp time are easily changed right at the drive. Each machine is provided with deceleration limit switches which allow the machine to decelerate to a stop rather than abruptly stop at the end of its travel. These machines also feature emergency over-travel limit switches and Fast-stop push buttons which bypass the deceleration ramp and shut the machine off immediately. The operation of these machines is Start/Stop/Reverse/Fast-Stop from any point of travel. Low voltage controls is standard on these machines. Each machine is supplied with a set of control buttons on the machine's control box as well as a remote control station. If versatility is a project requirement, this series of machines is the best option.
Model differences are based on horsepower of motor used. Configuration and size is same for all models.
Standard unit is equipped with:
- Rotary Limit Switches for decel to full open decel to full closed positions as well as overtravel.
- Low Voltage Control - 24 vac
- Remote Control Station (RCS1-TV)
- Fast stop (F-Stop) loop and pushbutton which provides instaneous stop of the machine, bypassing the deceleration ramps.
- Variable speed operation from 0 to 55 fpm
- Machine Guard
- Helical Grooved Drum 14"L x 6"D Provides up to 70' of travel
- Channel Steel Base
- Connects to 120 volt power supply Models 2907TV, 6507TV & 7007TV (230 volt, 3-phase is available as an option). Model 9007T available for use with 230 volt 3-phase power sources only. Must specify voltage when ordering.
- Approximate shipping weight 325 pounds
