emergency stop, dog everything. Responsibilities of signal person and crane operator.
• Load Dynamics & Lifting Principles: Center of gravity, sling angles (reduction factor), tension on
slings (load divided by 2 × sine of angle). Calculating sling tension at 60° vs 30°.
• Lift Planning & Critical Lifts: 75% of capacity rule for critical lifts (NYC standard for lifts near
capacity). Lift zones, load radius, swing radius clearance. Pre-lift meeting requirements.
• Ground Conditions & Support: Outrigger pad requirements (cribbing, matting), ground bearing
pressure, soil assessment. NYC requires competent person to inspect ground conditions before
setup.
• NYC-specific Requirements (1 RCNY § 3316-07): Inspection frequency (daily pre-shift, monthly,
annual by DOB-approved agency). Load test requirements.
• NYC Crane Operator’s License Classifications: Class A (All Cranes): Allows operation of all cranes
with capacity over 3 tons, including tower, mobile, and derricks. Class B (All Cranes
Limited): Capacity under 3 tons (hoisting machines). Special licenses for Concrete Pump, Tower
Crane, Pile Driver.
• Stability vs. Structural Failure: Causes of tipping (exceeding load radius, soft ground, outrigger
not deployed). Structural failure (boom buckling, mechanical failure).
• Pre-operational Inspection (Daily Checklist): Critical items: wire rope (broken wires, kinks, bird
caging), hook (cracks, throat opening, latch function), hydraulic hoses, outriggers, load moment
indicator (LMI).
• Wire Rope Rejection Criteria: Six randomly distributed broken wires in one lay, three broken
wires in one strand, one outer wire broken at the connection, kinking, crushing, heat damage,
diameter reduction.

• Emergency Procedures: Power failure (return controls to neutral, apply brake if possible, secure
load, warn area). Tip-over prevention (avoid sudden stops/swings, smooth operation).
• Wind Speed Restrictions: NYC restricts crane operation when wind speed exceeds 25 mph
sustained (or 35 mph gust for some cranes). Tower cranes have specific wind restrictions per
manufacturer.
• Signage & Swing Radius Protection: Barriers at swing radius to prevent personnel entry.
Outrigger and swing area barricades.
• Suspension & Dismantling (Jumping Tower Cranes): Climbing collar, hydraulic jacking frame.
Sequencing for raising tower crane. Weight limitations during jump.
• Pile Driving & Specialty Operations: OSHA 1926.603, vibration monitoring, pile hammer types
(diesel, hydraulic, drop). Distance from existing structures.
• OSHA Subpart CC (Cranes & Derricks): Scope (1926.1400), assembly/disassembly requirements,
ground conditions, operator qualification, signals, inspection, fall protection.
• Duty Cycle vs. Lattice vs. Hydraulic: Duty cycle cranes for repetitive heavy lifts (clamshell,
magnet). Lattice boom for heavy lifts, long reach. Hydraulic telescopic for versatility, speed of
setup.
• NYC Chapter 33 (Construction Safety): Demolition, crane operation near power lines (minimum
approach distances), protection of public, worker safety zones, suspended loads prohibition
over workers.
• Power Line Safety (OSHA 1926.1408-1411): Assured distance (20 feet minimum for lines up to
350kV), voltage determination, de-energizing requirements, equipment grounding.
• Load Moment Indicator (LMI) / Rated Capacity Indicator (RCI): Mandatory devices on cranes
over specific capacities. They warn when approaching capacity limits. NYC requires functional
LMI at all times.
• Assembly/Disassembly (A/D) Director & A/D Supervisor: OSHA requires qualified A/D Director
for complex assembly/disassembly. NYC requires DOB-permitted rigger supervision for
assembly.
• Hoisting Machine Registration (NYC DOB): All cranes/hoists must be registered with DOB;
stickers displayed on equipment. Transfer of registration.
• Failures of Structural Components: Boom collapse (overload, wind, defective weld), outrigger
failure (hydraulic leak, retraction under load, ground failure).
• Anti-Two-Block Device: Prevents contact between hook block and boom tip sheave. Automatic
cutout system. NYC requires function test daily.
• Tagline Requirements: Used for load rotation control, not for stabilizing suspended loads under
tension (use taglines to prevent spin, not for lifting). Synthetic rope approved.
• Operator Visibility & Blind Spots: Use of spotter / signal person when operator cannot see load
or landing zone. Telescoping and swing radius.
• Concrete Pump License (NYC-specific): Licensing requirement for concrete pump operators.
Distance and stability considerations.
• Temporary Heating Devices & Crane Operation: Restrictions on open flame near
fuels/hydraulics. No smoking or open flame within 50 ft of refueling area.
• Moving & Traveling with Load: Requirements for traveling with suspended load (smooth, slow,
rope vertical, warn personnel). Prohibited over personnel or critical structures without
barricade.
• Out-of-Service Criteria (Wire Rope, Hooks, Hydraulic Leaks): Tag out, report to supervisor,
suspend crane use until repair.
• Rigger & Crane Operator Coordination: NYC requires licensed rigger for certain rigging
operations. Communication between rigger and operator.
, Page 3 of 142
• Manbaskets & Personnel Platforms: OSHA 1926.1431 – hoisting personnel only when no
feasible alternative. Anti-two-block required, fall protection, tagline, operator must be present
at controls.
• Crane Owner Responsibilities: Maintenance records, load testing (annual, or after modification,
repair of load-carrying components), registration renewal every 4 years (NYC DOB).
• Suspended Scaffold / Hoist Maintenance (related to cranes for material hoists): Chapter 33
compliance, DOB permit.
• Hoisting Machine Categories in NYC: Category 1: Power cranes, derricks, tower
cranes. Category 2: Winches, chain hoists, material hoists.
• Material Hoist vs. Personnel Hoist: Restrictions, NYC DOB permit requirements, hoistway
enclosures, gates.
• Hydraulic System Safety: Burst valve/pressure relief. Sudden loss of pressure causing boom
drop (internal bypass).
• Controlling Contractor & Site Safety Manager (SSM) Role: Crane placement, lift oversight,
critical lift plan approval, coordination with DOB.
• Crawler Crane Track Pressure and ground bearing capacity calculation.
• Load Test: 110% of rated capacity for new/relocated/alteration. Annual load test as per NYC
(Class A cranes). Records.
• NYC Department of Transportation (DOT) Permits: Overweight/overdimension loads, street
closure permits for mobile crane travel.
• Fall Protection for Crane Operators: Guardrail system, personal fall arrest system (PFAS) for
access to cab from ladder. NYC rules on operator harness.
• Tagout / Lockout (LOTO) during maintenance or repair of crane hydraulic/electrical systems.
• Emergency Load Release (Jettisoning): Only allowed as last resort to prevent tip-over, injury to
personnel; requires warning.
