WARNING
The Vortek batten hoists are not designed to raise and lower people.
These hoists should NEVER be used for this purpose.
The Vortek ® hoist system is an automated rigging system with “dead-haul” hoists, meaning that the load is not
counter-weighted. Each hoist can lift loads only up to the design capacity. Overloading will result in electrical
overload protection shut down of the hoist and possible damage to rigging components.
Each hoist system consists of an integral electric motor driven gear reducer, directly coupled to a cable drum,
which winds steel cables (wire ropes) leading over sheaves installed within the hoist assembly and along the
structural steel of the building.
The Vortek hoist system consists of three basic parts:
Motor Electronic Variable Frequency Drive (VFD)
The Electronic Variable Frequency Drive and dynamic braking resistor for each motor are located in each Vortek
motorized hoist. A local control panel is located on each hoist for programming and diagnostics by factory
personnel. There is a reset-able circuit breaker located at each power point on the High Voltage Wireway
(HV-WW). The rated twist-locking plug on each unit acts as the main high voltage disconnect along with its
corresponding circuit breaker (CB).
hoist Assembly (Cable Drum, load Brake, limit Switches, and Frame)
The Vortek hoist assemblies are mounted on the rigging steel at the top of the stage house. The gear motor,
helically grooved cable drum, support bearing and frame structure are all factory assembled and tested. Maximum
upper height and minimum lower height are set by limit switches which are adjusted by factory-trained personnel
during installation and commissioning of the system. A position encoder is located at the brake end of each hoist
drum, attached directly to the drum shaft. Each hoist assembly is also equipped with a LOAD BRAKE, a unique
safety feature provided exclusively by Daktronics. This unit is designed to engage automatically when the load is
being lowered. This greatly reduces any possibility of a load to descend uncontrolled.
Daktronics E Series Controller
Control of all hoists is possible from the E Series enhanced control console. The hoists can be controlled
individually and at various set speeds. Please see the Controls Operation portion of this manual for the
operation procedures.
