ERMO4-1200/60 Four-Person Round Crane Man Basket
Product Description
The ERMO4-1200/60 is a four-occupant, crane-suspended personnel platform in Lifting Technologies’ Professional series, built for larger crews who need shared, 360-degree access around tall towers, large tanks, stacks, and other cylindrical structures from a spacious round basket with overhead protection. Its 60″ diameter platform provides ample room for four workers, tools, and materials, supporting crew-based maintenance, construction, and inspection tasks around large-diameter structures while remaining efficient to position under suitable cranes.
Engineered to comply with OSHA 29 CFR 1926.1431 for hoisting personnel and OSHA 1926.502 for fall protection, the ERMO4-1200/60 uses a high-strength 0.120″ wall square tubular steel frame, heavy-gauge steel floor grating, 42″ high guardrails, 6″ toeboards, perforated steel side panels from toeboard to mid-rail, an inward-swinging access gate with positive restraining device, and a full-perimeter inner grab rail providing personal fall-arrest anchorage. The 1,200 lb rated load capacity is intended for four workers plus shared tools, materials, and PPE, and the approximately 595 lb basket weight reflects the heavier-duty construction required for multi-person, full-crew work at height.
A dedicated base-attached suspension system uses a four-leg sling assembly of 1/2″ 6×36 IWRC wire rope secured to a master link, with each leg attached to the platform base using swage sockets and safety-threaded clevis pins; a fifth safety leg is used for tie-off to the load line above the overhaul ball to help maintain level orientation, reduce tipping, and align with OSHA personnel-hoisting requirements. Each ERMO4-1200/60 is proof-load tested at 1,500 lb—125% of its 1,200 lb rated capacity—before shipment and is supplied with Lifting Technologies’ easy-on/easy-off detachable test weight system, proof-load certificates, inspection checklists, access to a Lifting Technologies online training video, and a use and safety handbook to support compliant lift planning and site safety programs.
The ERMO4-1200/60 is used where four-person crews need crane-suspended access around large cylindrical structures—such as major stacks, towers, and tanks—while maintaining OSHA-compliant guardrails, 6″ toeboards, anchorage, overhead protection, and complete documentation.
Industrial Applications
Construction & Structural
Large construction and structural projects use the ERMO4-1200/60 for four-person crews working around major tanks, stacks, silos, and large-diameter columns where full-crew access around the circumference improves productivity. The 60″ diameter platform supports welders, fitters, inspectors, and helpers working together while overhead protection, 42″ guardrails, and 6″ toeboards help support OSHA-aligned fall protection in crane-suspended operations.
Power Generation & Utilities
In power generation and utility environments, ERMO4-1200/60 supports larger crews performing outage, upgrade, and repair work on stacks, tall towers, and large vertical equipment where multiple trades must be present at the workface simultaneously. The spacious round platform and 1,200 lb capacity allow four-person crews to stage tools and components at height while maintaining OSHA-compliant enclosure between toeboard and mid-rail and overhead-object protection.
Petrochemical, Refining & Heavy Industry
Refineries, petrochemical plants, and heavy industrial facilities use the ERMO4-1200/60 for multi-person work on large columns, vessel shells, and heavy process equipment where a full crew is needed at the elevation of the work. The four-person rating and 1,200 lb capacity support complex tasks such as major vessel repairs, heavy component handling, and multi-step inspection/repair sequences, while maintaining OSHA-compliant guardrails, 6″ toeboards, and personal fall-arrest anchorage.
Features & Benefits
Four-Person 60″ Round Work Area: The 60″ diameter round platform provides a generous shared workspace for four workers plus tools and PPE, supporting full-crew tasks around large cylindrical structures while allowing 360-degree access from a single lift position.
1,200 lb Four-Person Capacity: With a 1,200 lb rated load, ERMO4-1200/60 accommodates four workers and shared tools or materials, giving lift planners a high-capacity option for complex, crew-based tasks at height.
Professional-Series, OSHA-Compliant Construction: A high-strength 0.120″ wall square tubular steel frame, heavy-gauge floor grating, 42″ guardrails, 6″ toeboards, perforated side panels from toeboard to mid-rail, inward-swinging access gate, and a full-perimeter inner grab rail deliver OSHA 1926.502-compliant fall protection in a proven Professional design.
Overhead Protection for High-Risk Environments: An overhead frame with perforated steel skylights provides protection from falling objects while maintaining visibility and approximately 79″ interior height, supporting work in high-risk industrial, power, and construction environments.
Base-Attached Four-Leg Sling Suspension With Safety Leg: The base-attached four-leg sling assembly with 1/2″ 6×36 IWRC wire rope and a fifth safety leg tied back to the load line above the overhaul ball helps maintain level platform orientation, reduce tipping, and support OSHA 1926.1431 compliance for personnel hoisting.
Proof Load Tested With Detachable Test Weight: Each ERMO4-1200/60 is proof-load tested at 1,500 lb (125% of its 1,200 lb rated capacity) and includes Lifting Technologies’ easy-on/easy-off detachable test weight system, along with proof-load certificates, inspection documentation, and access to an online training video for safety and audit readiness.
Durable Powder-Coat Finish and Custom Options: An electrostatic powder-coat finish in standard solid red (with yellow test weights) offers resistance to impact, abrasion, chemicals, and corrosion; additional fall protection anchor points, tag lines, and other custom features can be engineered to meet specific site requirements.
Frequently Asked Questions
What OSHA regulations apply to the ERMO4-1200/60?
ERMO4-1200/60 is designed to comply with OSHA 29 CFR 1926.1431 for hoisting personnel with cranes and OSHA 1926.502 Subpart M for fall protection, including requirements for proof-load testing, 42" guardrail and 6" toeboard dimensions, enclosure between toeboard and mid-rail, and personal fall-arrest anchorage.
How much weight can the ERMO4-1200/60 hold?
ERMO4-1200/60 has a maximum rated capacity of 1,200 lb, which includes four workers plus tools, materials, and personal protective equipment. The basket itself weighs approximately 595 lb, excluding rigging, and each unit is proof-load tested at 1,500 lb (125% of rated capacity) before shipment.
How many people can work in the ERMO4-1200/60?
The ERMO4-1200/60 is rated for four occupants. Lift planning should allocate the 1,200 lb capacity between all workers and their shared tools and materials so that the total live load remains within the rated capacity.
When should I choose ERMO4-1200/60 instead of smaller round baskets?
Choose ERMO4-1200/60 when tasks require a full four-person crew at height with ample platform space for tools and components around large stacks, towers, or tanks; smaller models are better suited when crew sizes or work envelopes are more limited.
Does ERMO4-1200/60 include overhead protection?
Yes. ERMO4-1200/60 is supplied as a Professional round basket with overhead protection, using a perforated steel overhead frame to help shield workers from falling objects while maintaining clear sightlines and approximately 79" interior height.
