Boom with optional auxiliary hoist Boom with optional auxiliary hoist
Boom Pivot Bearing
Maintenance-free, capsuled spherical bearings ensure optimal transmission of force and maximal lifetime expectation.
The boom is a lattice framework construction with the boom tip being a shell structure which accommodates the luffing and main
hoist sheaves. The hoist winches (main and auxiliary winches) are located in the pivot section of the boom. A boom extension and
auxiliary hoist are available as an optional extra.
To achieve the required working outreach, the standard boom pivot sections and standard boom heads can be combined with variable
intermediate sections. For the connections between the various boom sections bolted flanges are provided.
Luffing and hoisting sheaves on the boom head are lubricated from a centralised greasing point located next to the boom head which is
accessible from the boom walkway. A hook garage is available for the main and auxiliary hoist.
