NAVAL SHIPS' TECHNICAL MANUAL - CRANES

INTRODUCTION
589-1.1.1 SCOPE. The intent of this chapter is to establish a basis for implementing a Shipboard Crane Certification
Program by identifying and consolidating the various operations, training, maintenance, testing, and
inspection requirements for cranes under the cognizance of the Naval Sea Systems Command (NAVSEA). The
Crane Certification Program is intended to maintain the reliability and safety of all shipboard cranes, and other
cranes under the cognizance of NAVSEA, and to provide the ship Commanding Officer and operational chainof-
command with a vehicle for verifying that the equipment is being operated, maintained, tested, and inspected
according to acceptable standards. The requirements set forth in the following sections should be considered
minimum standards and should not be construed as limiting the authority of a Command or a Type Commander
to impose additional requirements or devise more restrictive requirements. The philosophy of this chapter is that
each crane should meet a tightly-drawn set of material requirements upon completion of a shipyard overhaul, or
interim availability, so that the gradual relaxing of certain requirements, during the operating cycle, does not
affect safe and reliable crane operation. This philosophy is expressed by specific recertification test requirements
and a departure-from-specifications program.
589-1.1.2 APPLICABILITY. This chapter applies to the Operation and Maintenance (O & M) of all shipboard
mounted cranes and cranes assigned to forces afloat (including mobile cranes used aboard Aircraft Carriers)
except for the following:
a. Shipboard cranes designed and used only to handle reactor plant equipment. The technical requirements for
operation, maintenance, testing, and inspection of these cranes shall be accordance with: reactor plant manual
NAVSEA 0989-043-0000 Commissioned Surface Ship General RP Overhaul and Repair Specification ;
reactor plant manual NAVSEA 0989-037-2000 Commissioned Submarine General RP Overhaul and
Repair Specification ; equipment technical manual NAVSEA 0989-058-0000, Tender Nuclear Support
Facilities Preventive Maintenance Index ; or other applicable documents. In the absence of such information,
the requirements of this chapter shall apply.
b. Cranes specifically designed and installed only to handle weapons are controlled under NSTM Chapter 700,
Shipboard Ammunition Handling and Stowage. Where no conflict exists with NSTM Chapter 700 , the
requirements of this chapter may be used for guidance.
c. Overhead traveling cranes that do not handle weapons (for example, LSD-41 well-deck crane) are controlled
under NSTM Chapter 572, Shipboard Stores and Provision Handling. Where no conflict exists with
NSTM Chapter 572 , the requirements of this chapter may be used for guidance.
d. Floating (barge) cranes assigned to forces afloat for O & M and aircraft-crash cranes are controlled under the
requirements of Naval Facilities Engineering Command (NAVFAC) P-307, Management of Weight Handling
Equipment. Where no conflict exists with NAVFAC P-307, the requirements of this chapter may be used for
guidance.
e. Cranes used to launch and recover Deep Submergence Vehicles and diving systems. Specific design, opera-
tional, and certification guidence is given in NAVSEA SS800-AG-MAN-010/9290, System Certification
Procedures and Criteria Manual for Deep Submergence Systems and NAVSEA SS521-AA-MAN-010,
U.S. Navy Diving and Manned Hyberbaric Systems Safety Certification Manual, respectively. The existing
guidance shall be followed. Where no conflict exists with the existing guidance, this chapter may be used.
f. MCM-1 class stern crane, MHC-51 class multi-purpose crane, and MHC-51 class boat crane. The MCM-1
class stern cranes are controlled under the requirements of NAVSEA SG811–BD-MOO-010, Operation and
Maintenance Manual for Nonmagnetic Stern Cranes (Model S-536). The MHC-51 class cranes are controlled
under the requi
