Daktronics Hoist Operation and Maintenance Manual - Manual (Page 5)

Uniformly distribute loads.
Ensure loads are applied to 2 or more lift lines.
• Max. 1500 Pounds Total Applied Load Per Winch
• Maximum live load design capacity on each batten = 30 Pounds Per Linear Foot
• Do Not Concentrate Full-Capacity Point Loads on One Lift Line
Daktronics strongly recommend a thorough understanding of rigging practices
before any changes are made to batten loads. Many reference sources are available
that contain important information that will allow you to safely hang heavy loads
once you understand the limitations and dynamics of the materials used in rigging:
wire rope, pipe battens, etc.

The Vortek hoist system is a dead-haul system meaning that the load is not counter-
weighted. The 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.
The hoist unit consists of an integral electric motor driven 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 cables support battens for attaching the load. The battens can be lowered
to the lower hard struck limit to allow attachment of loads. Refer to installation
drawings for the exact location and dimensions.
Warning:
The VORTEK Batten Hoists are not designed to raise and
lower people. These hoists should NEVER be used for
this purpose.
