The NBT30H is one of
two models that Manitowoc Cranes introduced from its newly designed
line of National Crane boom trucks. The NBT30H is a redesigned version of National
Crane 1300H and retains a capacity of 30US tons (27tonnes). Boom and jib configurations were also unchanged
during the redesign, but there were several improvements on other systems.
The hydraulic system
has been completely standardized with the National Crane 900H, including the
pump, main control valve, hoist and hydraulic reservoir.
The boom truck’s Easy
Reach control and lever system was redesigned for compatibility with the CANbus
LMI system. It is also now made of stainless steel to improve the corrosion
resistance. The LMI display has been improved for better graphics and more
functionality, including an on-board display of error codes and a real-time
display of the outrigger position.
The NBT30H was accompanied to CONEXPO-CON/AGG 2011 by the larger NBT 55.
