Rope Hoisting
 This
type of hoisting harkens back to the period of maritime sailing. The same
engineering principles applied hundreds of years ago are employed to undertake
these operations today. This form of hoisting as truly an art form!
A Special
Rigger license allows the licensee to hoist articles of 1200 pounds or less
on the outside of any building in New York City. On occasion, placement of a
crane is physically impossible due to external field conditions, such as in the
back or on the side of a building or if the building height is beyond the
financial practicality of a crane. Dun-Rite has hoisted items by rope as high as
36 stories.
