BM3-900G 3-Person Rectangular Crane Man Basket
Premier Series | Three-Person | Rectangular | No Overhead Protection
Product Description
The BM3-900G is a three-occupant crane-suspended personnel platform built for crew-based maintenance and outage work where multiple workers need simultaneous elevated access. Its 36″ x 84″ rectangular footprint provides extended reach along beams, pipe racks, and structural steel while remaining narrow enough to fit between columns and in congested industrial layouts.
Designed to meet or exceed OSHA 1926.1431 requirements for hoisting personnel, the BM3-900G incorporates all-welded steel construction, 42″ guardrails with 6″ toeboards, an inward-swinging access gate, and multiple fall protection tie-off points to support three workers at height. The 900 lb rated capacity accommodates a small crew plus shared tools and materials, and the approximately 660 lb basket weight keeps overall suspended load compatible with a wide range of crane capacities and rigging configurations.
Like all Lifting Technologies Premier crane man baskets, the BM3-900G is manufactured in Missoula, Montana, and ships with comprehensive documentation, including proof-load test certificates, inspection checklists, access to Lifting Technologies online video training, and operator guidelines. Every unit is proof-load tested to 125% of its rated capacity—1,125 lb test weight—before leaving the facility, giving owners documented assurance of structural integrity and regulatory compliance.
The BM3-900G is widely used in power generation, petrochemical, and heavy construction applications where three-person elevated access significantly improves productivity for installation, repair, and inspection work. Its long rectangular deck allows crews to stage tools and components so they can service multiple work points along a structure without frequent crane repositioning.
Industrial Applications
Power Generation & Utilities
Power generation facilities use crew-sized platforms for major outage work where multiple technicians must access boilers, ducts, and structural steel together. The BM3-900G’s 3-person, 900 lb configuration supports boiler waterwall repairs, ductwork reinforcement, and multi-point inspection tasks where a small crew needs to work along long runs of structure from a single lift position.
Petrochemical & Refining
Refineries and petrochemical plants depend on personnel platforms for turnaround projects involving reactors, columns, and extensive pipe racks. The BM3-900G allows three-person crews to perform reactor external work, large vessel inspections, and pipe rack maintenance where multiple workers must coordinate tasks—handling tools, components, and test equipment along a linear work area.
Construction & Structural
Construction projects utilize personnel platforms for steel erection support, structural inspections, bridge and overpass work, and high-rise construction where mobility and quick repositioning are essential. The BM3-900G’s 36″ x 84″ footprint gives three-person crews space to perform connection inspections, structural repairs, and fireproofing or coating work along beams and girders, covering several connection points before repositioning.
Features & Benefits
Crew-Sized Work Platform: The 36″ x 84″ deck is sized for three workers plus tools and materials, allowing coordinated crew-based maintenance, inspection, and installation tasks at height without overcrowding the platform.
Extended Rectangular Reach: The long rectangular footprint provides exceptional reach along structural members, pipe racks, and bridge girders, reducing crane repositioning and improving efficiency on linear work scopes.
OSHA-Compliant Premier Construction: Built to comply with OSHA 1926.1431 for crane-suspended personnel platforms, the BM3-900G includes 42″ guardrails, 4″ toeboards, a self-closing access gate, and multiple personal fall arrest anchor points for three workers.
Proof Load Tested to 1,125 lb: Each BM3-900G is proof-load tested at 1,125 lb (125% of its 900 lb rated capacity) prior to shipment and ships with test certificates, inspection records, and serial-number traceability for safety files and audits.
Robust Weight-to-Capacity Balance: With a basket weight around 660 lb combined with a 900 lb rated capacity, the BM3-900G offers a robust structure while keeping total suspended load within the capabilities of many project cranes and rigging plans.
Frequently Asked Questions
What OSHA regulations apply to the BM3-900G?
OSHA 1926.1431 governs the use of personnel platforms suspended from cranes in construction, specifying requirements for proof-load testing, guardrail and toeboard dimensions, fall protection anchors, and inspection procedures. The BM3-900G is engineered and documented to help users comply with these standards.
How much weight can the BM3-900G hold?
The BM3-900G has a maximum rated capacity of 900 lb, which must include the combined weight of all three occupants, their tools, materials, and personal protective equipment. The basket weight of approximately 660 lb produces a total suspended load of about 1,560 lb, excluding rigging; each unit is proof-load tested at 1,125 lb (125% of capacity) prior to shipment.
How many people can work in the BM3-900G?
The BM3-900G is rated for three occupants. Lift planning should allocate the 900 lb capacity across three workers and their tools, typically budgeting a conservative per-person allowance to ensure total weight remains within the rated load when tools and small components are added.
When is a three-person rectangular basket preferred over smaller models?
A three-person rectangular basket like the BM3-900G is ideal when tasks require a small crew working together—such as handling larger components, coordinating weld and inspection activities, or covering a longer section of structure in a single lift. Smaller one- or two-person baskets are better suited to confined spaces or tasks that only require a single technician or pair of workers.
Can the BM3-900G be customized for specific projects?
Yes. Lifting Technologies offers custom options for the BM3-900G, including modified guardrail heights, additional tool or material storage, tailored rigging configurations, additional fall protection anchor points, and custom colors or markings for site identification. Custom solutions can be engineered to align with project-specific safety and access requirements.
What documentation is provided with the BM3-900G?
Each BM3-900G ships with proof-load test certification, operator guidelines, pre-use inspection checklists, access to Lifting Technologies online video training, and detailed product specifications. Additional documentation and support materials are available to help integrate the platform into site safety programs and regulatory compliance processes.
