How to use vacuum tube lifter for lifting paper bag ,kraft bag,resin bag,pp woven bag ?
(1) Operation of manipulating handle when lifting goods:
1. Three positions of Operating handle: 1, 2, 3. When the sucker is closely contacted with the cargo, the whole vacuum system can
only enter the valve of the control room, and the lifting and descending of the goods will pull or open the valve opening of the
control room by pulling the rod, so that the vacuum suction is greater than or less than the gravity of the cargo.
(1) Position 1 (Balancing position): the system is in a state of balance, which can not be lifted or put down the goods.
(2) Position 2 (lifting limited position): the pull rod is pulled up at this time, the valve intake of the control room is
completely sealed, and the goods rise rapidly. The position of the pull rod in the position of 1 and 2 determines the degree of
sealing, thus determining the speed of the lifting. The closer the pull rod closer to position 2, the faster the lifting speed;
(3) Position 3 (falling limit position): at this point, the air inlet of the control chamber opens when the rod is pressed down,
so that the vacuum suction is less than the weight of the goods, and the goods are descended. When the goods are placed on the
worktable or the ground, the goods can be put down and the suckers are separated from the goods.
2. The Function of regulating knob when No Loading:
When the load is not absorbed, the adjustment of this knob can adjust the natural length of the lifting pipe when no load
3. The Function of regulating knob when Loading:
When the load is absorbed on the suction cup, the pressure balance can be adjusted by press button
4. there is an upper quick change connection installed on the pressing in joint, and there is a quick change connection on each of
the two suction cups. Even when the spreader works, it can also complete the replacement of the sucker in a few seconds.
