Fatal Mobile Crane Collapse at Mercy Hospital Construction Site in Miami

30-Second Takeaway

A mobile crane partially collapsed during renovation work at Mercy Hospital in Coconut Grove, Miami, resulting in one fatality and four injuries. The incident involved a Tadano ATF 130G-5 operated by Sims Crane & Equipment while lifting equipment into the hospital. City officials confirmed that no patients were harmed. An investigation is underway to determine the cause of the boom failure, which occurred near the cathead.

Incident Overview

A serious crane incident occurred at Mercy Hospital in Coconut Grove, Miami, when a mobile crane partially collapsed during a hospital renovation project.

According to a press conference held by City of Miami officials, the incident resulted in:

• One fatality

• Four workers injured

Officials confirmed that no hospital patients were injured or disrupted as a result of the collapse.

What Is Known

• Location: Mercy Hospital, Coconut Grove, Miami

• Crane involved: Tadano ATF 130G-5

• Operator: Sims Crane & Equipment

• Task underway: Lifting renovation equipment into the hospital

• Failure point: Boom buckled near the cathead

• Outcome: Load dropped onto workers below

Emergency responders transported:

• Two injured workers to Mercy Hospital in stable condition

• Two injured workers to Jackson Memorial Hospital in serious but stable condition

Why This Incident Was Possible

Boom failures near the cathead occur in a high-stress region of mobile crane booms, particularly during lifts involving:

• High line tension

• Dynamic loading during final positioning

• Complex lift geometries in confined sites

Hospital construction sites introduce additional challenges, including restricted access, tight lift paths, and proximity to personnel.

Industry Reminder

Mobile crane operations near occupied structures carry inherent risk. When failures occur, outcomes can be severe due to proximity to workers and infrastructure.

This incident underscores the importance of lift planning, exclusion discipline, and structural integrity monitoring, especially on active hospital campuses.

How Incidents Like This Can Be Prevented

Critical Lift Classification

Lifts over occupied or sensitive facilities should be formally classified as critical lifts, requiring enhanced engineering review and supervision.

Load Path and Personnel Control

Strict exclusion zones beneath suspended loads are essential, particularly in renovation projects where trades are working nearby.

Boom and Structural Inspection

Regular inspection of high-stress boom sections, including areas near the cathead, helps identify early signs of fatigue or deformation.

Lift Planning in Confined Sites

Urban and hospital sites require detailed lift planning that accounts for limited swing radius, restricted setup, and emergency contingencies.

Stop-Work Authority

Operators and supervisors must retain full authority to stop operations if conditions change or if abnormal behavior is observed during a lift.
