The pull winch LT302 are intended as drag unit for pulling pipelines and inside-pipe devices in process of construction, repair and diagnosing underwater crossing of main pipelines.
The winch units and assemblies are installed on a frame that can place to semitrailer cart-horse with drive cart. The frame has in front and back parts removable axes for loading (unloading) winch from semitrailer. There are brackets on a frame front beam for anchoring winch. The winch operation could be realized on a semitrailer as well as without it.
A torque converter conjugating muff with engine is built in winch transmission for automatic change of speed of selecting rope subject to necessary strain. The speed of selecting rope is automatically increased under lowering load. The lowering load could occur as a result of pulling pipelines using auxiliary traction devices. The winch with torque converter quantity is especially important for pulling pipelines, when using usually traction devices with different tractive and speed characteristics.
A brake that control from cabin is placed to output shaft of torque converter for holding full tractive effort in a rope. For damping inertia of revolving drum, also the brake is placed in a countershaft. A regular rope layer is used for automatic rope placing to traction drum during use of winch.
The winch consists two rope sections of 23 mm diameter and 30 m length, hydraulic cylinder of loading gage, lanyards, rollers and complete of clumps for anchoring.
The winch has heating cabin from DT-75 tractor. The winch control is realized from this tractor. An apron from treatment recording unit (TRU) of engine, pressure and temperature oil of hydraulic system winch inspection tools are placed in the cabin.
