Ingersoll Rand "EA" series balancers are used for handling multiple (up to 3) loads within a 40-pound weight range without control adjustment. Balancers equipped with the EA control are designed to excel in high speed, constant weight, repetitive parts handling operations. The control positions are thumb actuated and are used to switch the unit to accommodate different load modes as required.
When the pendant is in the LO- and UN-LOAD position, balancer air pressure is released to allow the lighter loads to be in balance. When the pendant is in the HI-LOAD position, no pressure is released, and the heaviest load can be balanced.
The UN-LOAD position is also often used for handling device balancing (loaded/unloaded). Ingersoll Rand "EA" series balancers are used for handling multiple (up to 3) loads within a 40 lb (18.1 kg) weight range without the need to adjust the controls. When the pendant is in the LO- and UN-LOAD position, balancer air pressure is released to allow the lighter loads to be in balance. When the pendant is in the HI-LOAD position, no pressure is released, and the heaviest load can be balanced. The "EA" series balancers are ideally suited for applications where up to 3 load sizes are frequently lifted, and operator hands-on the part is required. The UN-LOAD position is also often used for handling device balancing (loaded/unloaded).
