ERMO3-900/48 Three-Person Round Crane Man Basket
Product Description
The ERMO3-900/48 is a three-occupant, crane-suspended personnel platform in Lifting Technologies’ Professional series, designed for small crews who need shared, 360-degree access around towers, tanks, stacks, and other cylindrical structures from a round basket with overhead protection. Its 48″ diameter platform provides a compact but functional work area for three workers and their tools, enabling coordinated tasks around curved structures while remaining efficient to position in congested industrial and construction environments.
Engineered to comply with OSHA 29 CFR 1926.1431 for hoisting personnel and OSHA 1926.502 for fall protection, the ERMO3-900/48 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 900 lb rated load capacity is intended for three workers plus shared tools, materials, and PPE, and the approximately 450 lb basket weight balances crew capacity with a total suspended load that works with many crane configurations.
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, helping maintain level orientation, reduce tipping, and align with OSHA personnel-hoisting requirements. Each ERMO3-900/48 is proof-load tested at 1,125 lb—125% of its 900 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 ERMO3-900/48 is used where three-person crews need crane-suspended access around cylindrical structures—such as stacks, towers, large process vessels, and columns—while maintaining OSHA-compliant guardrails, 6″ toeboards, anchorage, overhead protection, and complete documentation.
Industrial Applications
Construction & Structural
Construction and structural projects use the ERMO3-900/48 for three-person crews working around tanks, stacks, silos, and large columns where 360-degree access is essential and crew members benefit from standing together in a compact round platform. The 48″ diameter workspace allows welders, fitters, and inspectors to coordinate around curved surfaces 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, the ERMO3-900/48 supports three-person inspection and maintenance work on stacks, towers, and vertical balance-of-plant equipment where a round platform matches curved structures. Crews can share tasks such as stack inspections, ductwork repairs, and localized shell work while overhead protection and full-perimeter anchorage help align with plant safety programs.
Petrochemical & Refining
Refineries and petrochemical plants use the ERMO3-900/48 for column shell work, vessel-side tasks, flare-stack-related activities, and other three-person operations where a round platform provides even access around process equipment. The 900 lb capacity and three-person rating allow teams to share tools and materials in a single lift while maintaining OSHA-compliant enclosure and documented proof-load testing.
Features & Benefits
Three-Person 48″ Round Work Area: The 48″ diameter round platform provides a shared workspace for three workers plus tools and PPE, supporting coordinated crew tasks around cylindrical structures while minimizing the clearance needed to position the basket.
900 lb Three-Person Capacity: With a 900 lb rated load, ERMO3-900/48 accommodates three workers and shared tools or materials, giving lift planners a clear capacity and load margin for typical three-person 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 cost-effective Professional design.
Overhead Protection for Falling-Object Hazards: An overhead frame with perforated steel skylights provides protection from falling objects while maintaining visibility and approximately 79″ interior height, supporting work in environments with overhead hazard exposure.
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 ERMO3-900/48 is proof-load tested at 1,125 lb (125% of its 900 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 ERMO3-900/48?
ERMO3-900/48 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 ERMO3-900/48 hold?
ERMO3-900/48 has a maximum rated capacity of 900 lb, which includes three workers plus tools, materials, and personal protective equipment. The basket itself weighs approximately 450 lb, excluding rigging, and each unit is proof-load tested at 1,125 lb (125% of rated capacity) before shipment.
How many people can work in the ERMO3-900/48?
The ERMO3-900/48 is rated for three occupants. Lift planning should allocate the 900 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 ERMO3-900/48 over smaller or larger round baskets?
Choose ERMO3-900/48 when tasks require a three-person crew working around cylindrical structures and a 48" diameter platform provides enough room for tools and movement without the larger footprint and higher capacity of 60" models.
Does ERMO3-900/48 include overhead protection?
Yes. ERMO3-900/48 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.
What documentation comes with the ERMO3-900/48?
Each ERMO3-900/48 ships with proof-load test certification, operator guidelines, pre-use inspection checklists, access to a Lifting Technologies online training video, and the Lifting Technologies Use and Safety Handbook. Additional documentation for regulatory or site-specific safety requirements is available upon request.
