Sweed provides several different safety switches on all Sweed Choppers depending on individual needs. Safety switches help companies maintain the safety standards they’ve set for machinery operations within their facility, and can also help protect against unauthorized operation of equipment.
Brake motors are available for all Sweed Choppers Model 450 and up. This is an added “emergency stop” feature that completely shuts down the chopper and eliminates the kinetic energy from the flywheel; immediately stopping the flywheel from continuing to rotate, rather than coasting to a gradual stop.
Safety Exhaust Spillway Chute
This chute is a narrowed spillway that is attached underneath the machine and encompasses the exit point of the chopper. This added safety feature allows for the material to drop from under the chopper, while preventing any other foreign objects from entering up into the unit and into the knife path.
Machine In-Use Light Indicator
A good option for a noisy facility, this light indicator provides a visual for an operator to know the chopper is powered and running.
A ground fault circuit interrupter plug is available as an upgraded option for Sweed Chopper Models 300 through 450. This provides ultimate operator safety as it constantly monitors electricity and detects when current is flowing along an unintended path.
Momentary Foot Switch Pedal
This feature allows the operator to automatically start and stop the chopper by operating a foot switch pedal. It provides the operator with optimal safety when handling entangled or otherwise dangerous scrap during feeding. The Momentary Foot Switch Pedal is used in conjunction with a Separate Feedworks Motor.
Sound dampening options are available for individual machines and full enclosures that encase the entire scrap receptacle. Sound dampening provides a significant decrease in decibels and is beneficial for when processing heavy scrap metal materials that may exceed acceptable decibel limits while being chopped.
Auto Starts and Stops
Sweed Choppers can be equipped with custom starting and stopping systems using photo cells. These can ensure that your chopper starts and stops when the material is correctly fed.
Timers can also be installed to start and stop your machine exactly when the operator chooses.
Ensures that machine is shut off when there is an interruption in power and will not restart automatically when power is restored, endangering the operator. This feature is standard on the Model 513 and above, and is available as an upgraded option on all other choppers.
Most Sweed Choppers have the ability to split the infeed funnel. A split infeed provides the benefit of two choppers in one! These infeeds are designed to handle both banding and wire in one machine. Wire can be introduced into the feedworks on one side of the machine, and banding can be chopped in the other side. Each side is protected from the knife wear, associated with chopping the other material, effectively providing extended knife life.
Permanent Magnetic Clutch
The Permanent Magnetic Clutch assists in the synchronization of Sweed Choppers and the manufacturing line. This allows for variations between the chopper’s feed rate and the line speed of the material being produced. The Permanent Magnetic Clutch allows the operator to adjust the amount of torque that is needed to process the scrap while the chopper is out of operation.
Magnetic Particle Clutch
The Magnetic Particle Clutch assists in the synchronization of Sweed Choppers and the manufacturing line. This allows for variations between the chopper’s feed rate and the line speed of the material being produced. The Magnetic Particle Clutch allows the operator to remotely adjust the amount of torque that is needed to process the scrap “on the fly” while the chopper is in full operation.
Variable Frequency Drive (VFD)
VFD allows the user to adjust the frequency range that the motor on the chopper is operating under, thus varying the speed of the motor as required. Custom and Variable Infeed Rates Infeed speeds can be adjusted to allow for differences in the cut length of materials and operational needs.
Gas or Diesel Powered Motor
Available for offsite or remote locations where electrical services are limited or unavailable. Multiple Knife Configurations Every Sweed Chopper comes standard with a single knife flywheel. However, with multiple knives cutting scrap material, faster infeed speeds or smaller cut lengths can be obtained. The need for additional knives is dependent on scrap material and operational needs.
Custom feedworks that allows the Sweed Chopper to interface with a robotic arm that feeds the unit scrap materials.
Hydraulic Powered Infeed Systems
For heavy duty scrap requiring enhanced pulling capability. Available on the Model 5503 and up.
