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 extracts these hazardous fumes from the source, and then safely returns the hose and nozzle back to the starting position automatically.

Safety and efficiency on site
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.

How CRS works
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.

Easily retrofitted on existing Plymovent STR
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. 

Remote control
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.

Mike Nevin figured it was a prank. There's no way the city is now requiring firefighters and medics to clean up blood from crime and accident scenes without the proper training or equipment, the president of the Detroit Fire Fighters Association told himself. “I thought it was a joke when I first saw it,” Neven tells Metro Times.

An Atlantic City firefighter filed a federal civil rights lawsuit against the city and the department’s chief and deputy chief after learning he would be suspended without pay unless he shaved his beard, which he has grown out for religious reasons. Alexander Smith, who has worked for the fire department for more than 15 years and makes $115,000 a year as an air mask technician, is a born-again Christian who began growing out his beard in December as an expression of his faith, according to a lawsuit filed last week.
