Intuitive load handling with pneumatic balancer

Moving loads – almost weightless

You can experience the pneumatic control when you move loads weighing up to 350 kg in an almost weightless way. The Demag D-BP II Air Balancer is ideal for assembly processes, repairs and industrial production tasks in many industries, including the manufacturing and automotive industries. Designed to complement the manual lifting process, the D-BP II moves with the natural lifting motion of the operator.

Load handling with ease 

Lifting and positioning of loads, especially fragile loads, is assured by the jerk-free, continuous three-dimensional movements. Thanks to load balancing, loads of different weights can be lifted at almost identical speeds, and picking up and setting down can be conveniently controlled. You can choose between a manual control with control elements or a manual force exerted control for loads weighing up to 70 kg. Or you can choose a combination of both!

The D-BP II Air Balancer is therefore an optimal solution for fast pick-and-place operation. The compressed-air drive facilitates low-noise operation with a maximum level of 70 dB(A). In addition, the pneumatic drive has a virtually unlimited service life, provided regular maintenance is performed. Air Balancers do not need an electric power supply, the pneumatic energy supply can be connected by any specialist fitter when the equipment is installed.

High level of safety 

The D-BP II is equipped with a patented safety brake to block the rope if the lifting motion is too fast and manages uncontrolled motion with the quick and easy brake reset. The overload protection arrangement of the Air Balancer is wear-free. Optional features can enhance safe load handling: its interlock function can detect an attached load and can prevent a suspended load from being accidently released if a suitable load handling attachement is used. The additional BaseLoad function keeps the air pressure level in the balancer at a safe level. The deadweight of the gripper does not act on the load after it is lowered.

Many suspension possibilities

Whether you need fluid, precise lifting in automotive assembly lines, manufacturing, or industrial production, the D-BP II Air Balancer travels smoothly and efficiently on all ceiling hung Demag KBK light crane systems, freestanding workstations and jib cranes.
