Customer: On video capture with two oval suction cups at least 250x100. So this gripper with a vacuum of -30 kPa will easily lift loads weighing 60kg. The customer has cardboard on good quality boxes. If the cardboard is porous, this gripper will lift 40kg. These calculations have a safety factor of 2. The suction pads on your grip will be able to be exchanged for bigger ones if necessary, this is no problem.

If there is a specific (working) proposal, I look forward to hearing from you. 

RAMHOIST: pls check the the final appearance of vacuum lifter in the end of this link:



RAMHOIST: same function, but different style, we will use the first style on this application
the second style is used for sliding rail, it doesn't suit on mobile machines

Customer: We could not offer our client a "raw" project. We get scattered information from you. There are "pieces" of different products in one proposal.
The customer's need remains.
Again about the project.
Vacuum hose hoist for unloading sea containers. Moving cardboard boxes weighing up to 40 kg. Movable unit ( not necessary with a drive, you can roll a cart). The unit rolls up or drives into the container. Aperture below the ceiling. The grip must ensure the unloading of boxes stacked to the ceiling. Drive the elevator pump from a battery-powered motor. Battery charge should be enough for 5 hours of continuous operation. If there is no possibility to install batteries on the elevator platform, you can use a separate cart and connect it to the motor with a cable.
