Sack Lifting

Lifting – Find out how we lift sacks regardless of placement or material
LaborSave automatic sack emptying system has the most advanced lifting mechanism in the industry, assuring maximum efficiency, essentially zero waste of material, and total safety.

After the pallet with sacks is loaded into the loading dock, a series of robotic sensors automatically control the entire lifting process.

  1. The gripper drops to collect the sacks at a quick speed of over a meter a second. As the gripper approaches the sacks, the system automatically slows down the gripper so that it gently lands on the top layer of sacks.
  2. Once the gripper is resting on the top layer of sacks, the gripper's claws grab the sacks at an angle that only creates one hole from the top of the sack; preventing leakage of the contents or tearing of the sack during the lift.
  3. The claws grab the top layer of sacks, regardless of number of sacks, setup, orientation or position. Sacks can be positioned in any direction or angle and they will all be picked up and brought to be cut and emptied.
  4. When the gripper lifts the last layer of sacks from the pallet, there is the option of keeping the sacks in the air until a visual inspection is completed to insure that no pieces of pallet or other contaminants are stuck to the bottom of the sack. After visual approval, the bags are taken to be slit. (This is an optional feature that can be overridden.)
  5. After the gripper has processed the final sacks, the system automatically determines that only the empty pallet remains and commands the gripper to stop operating automatically.
  6. The entire LaborSave system in enclosed within a safe, rigid grid. As the loading dock is the only area where the LaborSave is “open”, the sensors on the side create an invisible seal which automatically shuts down the machine should any object pass the loading dock entrance during operation. The speed at which the sensor is capable of shutting off the gripper is enough to prevent injury of either a fall or quickly placing a hand within the loading dock area.
