The Crab Return System (CRS) fosters productivity by eliminating the need for an operator to physically retrieve the exhaust extraction hose and nozzle after they have been disconnected from a vehicle.
Moving cars and trucks in workshops, service facilities, governmental inspection environments and fire stations, emit hazardous fumes into the workshop air. The Crab Return System (CRS) can serve as a core component in the Plymovent exhaust removal system, as it helps extract these hazardous fumes from the source, and then safely returns the hose and nozzle back to the starting position automatically.
The Plymovent Crab Return System improves both worker safety and efficiency. How? By conveniently returning the exhaust extraction hose and nozzle to the precise start position for operators as a vehicle enters the facility. This eliminates the need for an operator to walk through a facility to retrieve it, encouraging the proper usage of the Plymovent vehicle exhaust extraction system and fostering greater productivity.
Because the nozzle is following the movements of the vehicle, the CRS minimises the amount of hose hanging in a facility compared to traditional vehicle exhaust extraction systems. As a result, less obstructions improve the visibility of the operator.
Attach one of the extraction nozzles to the vehicle’s exhaust tailpipe. As the vehicle moves through the facility, the CRS enables the hose to move along with it. When the vehicle exits the facility, the nozzle can be detached manually by the user or automatically. The CRS returns the nozzle and hose to the original starting position by the operator via a remote control, or automatically via a sensor.
If you already have a Straight Rail System (STR) in use, the CRS can easily be installed upon your STR system and will fit either the internal crab system (IC) or the external crab (EC) system.
The unit contains a basic manual remote-control start set. It is possible to add more remote controls to the system to create a maximum ease of use out of your Crab Return System.
Another option to return the nozzle is the automatic sensor return trigger to engage the CRS, in conjunction with the well-known Pneumatic or Magnetic Grabbers® of Plymovent.
The Crab Return System includes an emergency override allowing the operator to stop the system at any time.

Take a look at these options!
The Sliding Balancer Track (SBT) has set the standard for exhaust extraction of fire and emergency vehicles around the world. SBT is the preferred rail system for back-in applications.
The Straight Rail (STR) is designed for drive-through applications with up to four vehicles parked in tandem.
The Mini Rail Profile (MRP) system is an exhaust extraction system for emergency service stations and other facilities with confined spaces and/or low ceilings.
Vehicle Square Rail - External Crab (VSRX) is the ideal solution for heavy-duty vehicles that move through an apparatus garage up to 120 ft (36,5 m) in length.
The Vertical Stack Rail (VSR) is the solution for vehicles that have top exhaust and need to move through a garage or station.
