High-Rise Hoisting Systems

Move materials from truck to floor without slowing down the tower crane or elevators.

Keep the tower crane on-task and finish the project faster.

When the tower crane stays on-task building the structure taller, you’ll finish the project faster. Contractors using a DOC® Hoisting System are able to move more material than an elevator without slowing down the tower crane. Less demand for the elevator means less waiting and increased productivity.

DOC® Material Hoists are capable of hoisting 8,000lbs of bulky materials that normally wouldn’t fit inside an elevator. An extendable jib allows the DOC® Material Hoist to extend outward from the building, making it possible to move very large materials like curtainwall and pipe directly off the truck, straight to the floor.

Luffing boom allows for extra-long materials to be rotated and maneuvered into floors below.

Keep the tower crane on-task and let DOC handle the extra-long materials like pipe and curtainwall.  Trucks can be unloaded in a fraction of the time it typically takes waiting for the tower crane, reducing traffic congestion on the street and speeding up the project considerably.

Perfect solution for accessing inner floors on smaller projects.

For smaller buildings, remodel projects, or situations with limited access through exterior openings, our Material Basket can provide bulk material delivery to inner floors through a small window opening.  The lightweight Material Hoist can be mounted on practically any rooftop.


Having a DOC Material Hoist + Basket on-site drastically speeds up delivery of large bulky items like cabinets, plumbing, fixtures, electrical, and much more.

The DOC Material Hoist solves many problems that add delays to high-rise construction projects:

Is your tower crane always running behind schedule?

Adding a DOC Hoisting System to your project allows sub-contractors to unload and deliver their own materials without taking time away from the tower crane.



Are your sub-contractors resorting to using the elevator to move their materials?

When the tower crane misses a pick time for materials, sub-contractors often resort to moving their materials in the elevator, adding wait time and slowing the elevator to a crawl.  With a DOC Material Hoist moving all of the materials, elevators can move people, improving productivity throughout the workforce.



Are you racking up significant overtime costs moving materials after-hours and on weekends?

When demand for the elevator and tower crane is high, many resort to moving materials during off-hours.  Keep overtime costs in check by adding a separate Material Hoisting System that can move materials during regular job site hours.



Do you have a tight job site or limited lay-down area for materials?

By unloading materials themselves, contractors using a DOC Hoist don’t need a staging area to store materials on the ground.  The DOC Material Hoist can unload materials directly from the truck without touching the ground.
