Using a DOC Material Hoist, high-rise contractors move more than twice the material in half the time, with half the labor.


Traditionally, contractors opt to move job site materials in the on-site construction elevator.  While this might seem like the easiest option, often many elevator-related delays go unnoticed and unfixed.  By keeping construction materials out of the job site elevator, contractors using a DOC Material Hoist system report savings of up to 80% in material-handling labor costs.






Although against OSHA regulations, mixing laborers with materials in construction elevators is unfortunately still one of the most common job site injuries.  By reducing the amount of hand-loading labor needed to move materials from floor-to-floor, chances of labor-related injuries are reduced.  In situations where elevators are not available at all, having a DOC Material Hoist on-site can save laborers countless stairs, and decrease the likelihood of injury or exhaustion.

Compared to a tower crane, the DOC Material Hoist does not move loads horizontally overhead across the entire job site.  Instead, the DOC hoisting zone is confined to approximately 20ft by 20ft where all material handling is performed.  DOC Hoists and Decks feature an innovative telescoping design that leaves no pieces of equipment jutting out from the building.  Safety hand-rails and locking gates also provide a safe working platform when loading materials on or off the decks.  These innovative safety features combine to make operating and working around the DOC system safe and enjoyable.




Located near Seattle, one of the fastest-paced construction markets in the world, DOC knows what it means to stay ahead of schedule in the lucrative high-rise construction industry.  When so much can go against you slowing your project down, having the ability to keep up with workforce and material demands is essential to staying on track in today’s markets. By moving twice the material with half the labor, DOC provides you with more material handling options to keep your project running at top speed.

Contractors in some of the fastest construction markets rely on DOC to relieve the burden placed on the construction elevator and tower crane in order to keep projects on track. Most high-rise construction contractors and laborers know the frustration of waiting for the construction elevator to take you home or to lunch. When an already busy elevator system is delegated to move materials, people aren’t able to use that elevator to get around and do their jobs efficiently.

When moving building materials from truck to destination using the elevator, you can expect the process to go something like this:

  1. Break-down materials crates on the truck into manageable pieces.
  2. Move material from truck to cart.
  3. Cart material from street to elevator.
  4. Wait for the elevator.
  5. Load elevator and send to crew on destination floor.
Time spent waiting for a clogged elevator can add costly hard-to-track delays to your project. Many contractors are quick to write-off those delays as the cost of building a skyscraper, and fail to see the benefit of streamlining the handling workflows. By capitalizing on innovative DOC High-Rise Material Hoisting solutions, contractors and project managers are able to increase the productivity of the entire workforce, while at the same time decreasing costs and overtime labor.
Contractors using a DOC Material Hoist are used to a process that goes a bit like this:

  1. Rig crates of material on the truck.
  2. Lift load up to destination floor.
  3. Extend deck and land load.
  4. Retract Deck

It doesn’t get much easier and smoother than that.

Compared to a typical construction elevator, the DOC Material Hoist system can move roughly twice the amount of material in half the time with half the labor.  A 4 person team unloading material directly from the delivery truck with the DOC Hoist can easily outperform an 8-person team unloading the truck and hand-loading materials inside the elevator.  When you multiply this labor savings over the entire course of a high-rise construction project, the results can be shocking.  Some contractors report saving as much as 80% on material-handling labor costs.  Now that’s something to get excited about!

The DOC Material Hoist was designed to be installed on any floor of a high-rise building.


DOC Material Hoists and Decks are installed on either an inner-floor or roof of a building without any permanent attachment.  For inner-floor installation, shore posts are installed between the Hoist and Deck frames for quick and reliable installation.  The DOC Material Hoist can be installed on the roof of a building using supplied counterweights.  Both of these methods are non-invasive and do not require drilling holes or bolting down equipment to sub-floor or framing of the structure.

Contractors will generally install the DOC Hoist in a location that allows large trucks to park underneath.  Because of the DOC systems flexible installation methods, positioning the DOC Material Hoist in the most advantageous location is simple and easy.  Each system comes with a detailed Operator’s Manual with step-by-step assembly, installation and operation instructions.  Additionally, our world-class support team is here to assist you throughout the entire process.


The DOC Material Hoist comes with a 2.4Ghz wireless remote, capable of controlling the hoist up to 1 mile away.  This allows the hoist operator to move around the job site to the best possible vantage point, making operation intuitive and comfortable.  An obstruction-free loading area makes moving large and long loads trivial.  And since the DOC Hoist is technically not a crane, operators do not need crane certification in order to operate.  Operators need only be instructed on how to use the DOC Material Hoist, just like any other job site equipment.
