Powered by a 24v rechargeable battery the libro 250 compact has an electrically adjustable rack and pinion counterweight saddle which can be moved along the machine s rear beam by cable remote control.
Counterweight lifting beam.
The basic concept of the counter balance beam is to use variable amounts of counterweight to offset the weight of the targeted lift.
By traversing the counterweight along the length of the beam the target item is smoothly lifted from its location.
Capacity is marked on the beam.
Counterweight moves along beam to balance load gear box and counterweight remote controlled increases efficiency and reduces crane operator risk single line single pick point system beam lengths up to 33.

Counterweights are often used in traction lifts elevators cranes and funfair rides.
Beams with shackles have lifting eyes and shackles that adjust with screw pins.
This design can be adapted to different lift beam configurations and other capacities.
Also known as spreader beams these beams adjust to stabilize long or unbalanced loads when lifting.
Beams with brackets have adjustable brackets and lifting eye.
Counterbalance beams at the other end of our range the libro 250 compact overhang beam can lift up to 250kg with a 0 8m depth of overhang.
The force balance can be expressed as.

Tandemloc engineering designed and built a load tested gear driven adjustable counter weighted lifting device that allowed the lids that were of different weights and sizes to be removed quickly and safely.
Its purpose is to make lifting the load more efficient which saves energy and is less taxing on the lifting machine.

A counterweight is a weight that by exerting an opposite force provides balance and stability of a mechanical system.
In addition for a beam in balance the algebraic sum.
