GENERAL
This manual has been compiled to assist you in properly
operating and maintaining your Model NBT40 SERIES
National Crane (Figure 1-1). The NBT40 series includes
crane models NBT36, NBT40, and NBT45.
Before placing the crane in service, all operators and
persons working around the crane must thoroughly read and
understand the contents of this manual pertaining to Safety,
Operation and Maintenance. Before moving a vehicle
equipped with the crane, information relating to transporting
the vehicle must be read and observed.
This manual must be retained with the machine for use by
subsequent operating personnel.
Information in this manual does not replace federal, state or
local regulations, safety codes or insurance requirements.
For detailed information concerning the operation and
maintenance of the RCL system installed on the crane, see
the manufacturer’s manual supplied with the crane.
Manufacturers of rated capacity limiters may refer to them in
their manuals as a load moment indicator (LMI), a hydraulic
capacity alert system (HCAS), or a safe load indicator (SLI);
Manitowoc refers to these systems as a rated capacity limiter
(RCL) throughout its Operator’s and Service Manuals.)
The NBT40 SERIES has been designed for maximum
performance with minimum maintenance. With proper care,
years of trouble-free service can be expected.
Constant improvement and engineering progress makes it
necessary that we reserve the right to make specification
