Specialty Hoists

Conmaco can design and build a Hoist for any application.  We can also modify and/or rebuild existing equipment to meet your requirements.  A few examples include winches for Tower Erection, Pipeline Pulls, Cable Spooling Machines, Barge Moving Systems, and Abandonment and Recovery (A&R) Winches.

 

This DMW-250 Single Drum Winch was completely reconditioned and repowered to perform Abandonment and Recovery service on a Pipe laying Barge in the Gulf of Mexico.

The Amcon JU-36 utilizes a diesel driven closed loop hydraulic power unit to provide precise load lowering control.

The closed loop hydraulic system of the JU-36 is ideally suited for load lowering and load positioning.  The operator directly controls the amount of fluid flowing from the hydraulic pump and therefore the speed of the hoist from the hydraulic joystick.  The hydraulic motor automatically selects the maximum speed that it can operate based on the load that is being raised or lowered. 
This feature allows the hoist to use the full horsepower of the diesel engine and therefore maximizing efficiency.  Equal performance is delivered for raising or lowering loads.  The hydraulic oil is cooled by a generously sized shell and tube heat exchanger that is plumbed into the diesel cooling circuit.  The following tables show the winch performance.  The first table shows the maximum line pull and associated speed for that line pull at each layer.  The second table shows the maximum line speed and the associated line pull at that speed at each layer.  The data was calculated using 1.5" wire rope

The AMCON Model 385 HDS is one of CONMACO/RECTOR L.P.'s most versatile winches.  This constant horsepower, rugged, closed-loop hydraulic winch is designed not only for mooring applications, but is ideal for hoisting and load-lowering applications.  By utilizing a double hydraulic motor (two motor groups in one housing), the winch has a greater speed range than other hydraulic winches.  Also, a separate power unit, able to be located up to 50 feet away, allows this winch to fit into places where other winches cannot.
