Balance Mechanism - LBM800 Series

A new benchmark has been set for all bottom loading arms wit the introduction of the LBM800. This state of the art design is essential when you require safety and long service life with minimal maintenance.

The ‘bulletproof’ LBM800 provides effortless bottom loading in petrochemical distribution depots through the use of the unique design known as the ‘Velvet Touch’.

The ability of 360° rotation in the horizontal plane allows the LBM800 to easily move from a parked to loading position, to service vehicles on either side of the loading bay. While the vertical plane swivel allows users to position the coupler at different heights within the API envelope.
