Domain 4: Manufacturers’ Load
Charts
(Approximately 35% of the test)
DOMAIN 1: SITE
(Approximately 12% of the test)
1. Know the proper use of mats,
blocking or cribbing and outriggers
or crawlers as they affect the suitability
of supporting surfaces to handle
the expected loads of the operation.
2.
Know the limitations of machine
clearances, extension of crawlers
or outriggers/stabilizers and counterweights.
DOMAIN 2: OPERATIONS
(Approximately 30% of the test)
1.
Know how to inspect the crane for unsafe conditions,
complete required records and communicate the
unsafe conditions to the proper authority.
2. Know how to pick, carry,
swing and place the load smoothly and safely
on rubber tires
and on outriggers/stabilizers or crawlers (where
applicable).
3. Know proper boom assembly and disassembly
techniques:
(a) lattice booms,
(b) extension and retraction of
“power pinned” and/or
manual boom “extension”,
(c) erection and dismantling of
lattice extension jibs.
4. Know how to react to changes in conditions
that affect the safe operation of the crane.
5. Know how to shut down and secure the crane
properly when leaving it unattended.
6. Know how to prepare the crane for transportation
by loading or unloading on trailers and be familiar
with the differences between rail and barge loading.
7. Know how to move the crane (no load) safely
under its own power:
(a) between job sites,
(b) within job sites,
(c) loading and unloading on trailers.
8. Know the manufacturer’s
specifications for operating in various weather
conditions and
understand how environmental conditions affect
the safe operation of the crane.
9. Know how to properly level the crane.
10. Know how to perform daily maintenance and
inspection.
11. Know how to use the following operator aids:
(a ) wind indicator,
(b) anti-two block device,
(c) boom angle indicator,
(d) load indicating device,
(e) boom length indicators,
(f) drum rotation indicators.
12. Know the proper procedures for operating
safely under the following conditions:
(a) traveling with suspended loads,
(b) approaching two-blocking,
(c) operating near electric power
lines,
(d) using suspended personnel platforms,
(e) using other than full outrigger/crawler
extensions,
(f) lifting loads from beneath the
surface of the water,
(g) using various approved counterweight
configurations,
(h) handling loads out of the operator’s
vision (“operating in the
blind”),
(i) using electronic communication
techniques, such as radios.
13. Know emergency response procedures for:
(a) fire control,
(b) electric power line contact,
(c) loss of stability,
(d) control malfunction,
(e) two-blocking,
(f) overload,
(g) carrier or travel malfunction.
DOMAIN 3: TECHNICAL KNOWLEDGE
(Approximately 23% of the test)
1. Know the functions and limitations
of the crane and attachments.
2. Know basic crane terms.
3. Know the basics of machine power flow systems:
(a) mechanical,
(b) electrical,
(c) pneumatic,
(d) hydraulic,
(e) combination.
4. Know how the boom hoist and load hoist(s)
are driven and engaged to the power source.
5. Know the requirements of standard and optional
controls.
6. Know the requirements of pre-operation inspection
and maintenance.
7. Know how to use
operational assist devices which
include:
(a) anti-two block,
(b) load moment indicators and rated
load
indicators,
(c) outrigger position indicators,
(d) mechanical levels,
(e) boom angle indicators,
(f) load indicating devices,
(g) boom stops and boom hoist disconnect,
(h) radius indicators,
(i) drum rotation indicators,
(j)
boom length indicators.
8. Know how to use
manufacturer approved attachments
and their effect on the crane.
9.
Know the function and safe use of
crawler position (extended or retracted),
outriggers, and/or stabilizers.
10.
Know how to assemble and disassemble
boom sections, extensions and jib.
DOMAIN 4: MANUFACTURERS’ LOAD
CHARTS
(Approximately 35% of the test)
1. Know the terminology necessary to use load
charts.
2.
Know how to use load charts. For
example:
(a) the operational limitations
of load charts and footnotes,
(b) how to relate the chart to the
configuration of the crane, crawlers
or outriggers extended or retracted,
jib erected or offset, and various
counterweight configurations,
(c) the difference between structural
capacity and capacity limited by
stability,
(d) what is included in load chart
capacity,
(e) the range diagram and its relationship
to the load chart,
(f) the work area chart and its
relationship to the load chart,
