BM3-900S 3-Person Rectangular Crane Man Basket With Overhead Protection
Premier Series | Three-Person | Rectangular | With Overhead Protection
Product Description
The BM3-900S is a three-occupant crane-suspended personnel platform with integrated overhead protection, built for crew-based maintenance, construction, and outage work where multiple workers need simultaneous elevated access under overhead piping, steel, or equipment. Its 36″ x 84″ rectangular footprint offers extended reach along beams, pipe racks, and structures while maintaining a narrow width that fits between columns and through congested plant layouts.
Designed to meet or exceed OSHA 1926.1431 requirements for hoisting personnel, the BM3-900S features all-welded steel construction, 42″ guardrails with 6″ toeboards, an inward-swinging access gate, and multiple fall protection anchor points, along with a fixed overhead frame with perforated protection panels above the crew. The 900 lb rated capacity accommodates a three-person crew plus shared tools and materials, while the approximately 870 lb basket weight reflects the robust frame and canopy yet keeps the total suspended load within typical project crane capabilities.
Like all Lifting Technologies Premier crane man baskets, the BM3-900S is manufactured in Missoula, Montana, and ships as a turnkey package: four-leg sling assembly, detachable test weight system, access to Lifting Technologies online video training, and documentation including proof-load test certificates, inspection checklists, and operator guidelines. Each unit is proof-load tested to 125% of its rated capacity—1,125 lb—before leaving the facility, providing documented assurance that both the basket and the overhead protection system are ready for personnel lifting.
The BM3-900S is widely used in power generation, petrochemical, and construction applications where three-person crews must work together at height in areas with overhead hazards. Its long rectangular deck with canopy allows teams to coordinate welding, inspection, or installation work along extended structures while reducing exposure to minor falling debris or incidental contact with overhead members.
Industrial Applications
Power Generation & Utilities
Power generation facilities use crew-sized platforms for major outage work on boilers, ducts, precipitators, and surrounding structural steel where overhead steel, cable trays, and equipment create added risk. The BM3-900S’s 3-person, 900 lb configuration with overhead protection supports boiler waterwall repairs, ductwork reinforcement, and inspection programs where crews must work beneath overhead members and want an added protective barrier above the platform.
The 36″ x 84″ footprint gives teams enough room for welding machines, NDT tools, and consumables while the overhead frame helps shield them from small debris and scale, making it well suited for turbine hall and boiler house outage tasks.
Petrochemical & Refining
Refineries and petrochemical plants rely on crane-suspended personnel platforms for complex turnaround activities involving reactors, columns, and dense pipe racks. The BM3-900S allows three-person crews to perform reactor externals work, large vessel inspections, and pipe rack maintenance in units where overhead piping, cable trays, and structures increase dropped-object concerns.
Its long rectangular deck and overhead protection structure support multi-worker tasks—such as coordinating tools, components, and inspection equipment along pipe racks or column shells—while helping reduce exposure to minor falling items in congested process areas.
Construction & Structural
On construction and structural projects, crew-sized baskets are used for steel erection support, retrofit work, and bridge or high-rise construction where multiple workers must operate together under beams and decks. The BM3-900S provides a protected rectangular platform for three-person crews performing connection work, bracing installation, and finishing tasks beneath overhead steel, bridge decks, or canopy structures.
The 36″ x 84″ footprint allows crews to service multiple connections or details per lift, while the overhead frame adds protection from small falling debris during construction, punch-list, and retrofit activities.
Features & Benefits
Three-Person Rectangular Work Platform With Canopy: The 36″ x 84″ deck provides space for three workers, tools, and materials, while the integrated overhead protection helps safeguard crews working under piping, ducting, or structural steel.
Extended Reach for Crew-Based Tasks: The rectangular footprint delivers extended reach along beams, pipe racks, and bridge girders, allowing crews to cover multiple work points from a single lift and reducing crane repositioning on linear work scopes.
OSHA-Compliant Premier Construction: Built to comply with OSHA 1926.1431 for crane-suspended personnel platforms, the BM3-900S includes 42″ guardrails, 6″ toeboards, an inward-swinging, multiple fall protection anchor points, and a dedicated base-attached suspension system that enhances platform stability.
Proof Load Tested to 1,125 lb: Each BM3-900S 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 documentation and audits.
Robust Weight-to-Capacity Balance With Overhead Protection: With an approximate basket weight of 870 lb and a 900 lb rated capacity, the BM3-900S combines heavy-duty construction and canopy protection with a total suspended load that remains manageable for many construction and industrial cranes.
Frequently Asked Questions
What OSHA regulations apply to the BM3-900S?
OSHA 1926.1431 governs the use of crane-suspended personnel platforms in construction, including requirements for proof-load testing, guardrail and toeboard dimensions, fall protection anchors, and inspection procedures. The BM3-900S is engineered and documented to support compliance with the standard, covering both the platform and overhead protection system.
How much weight can the BM3-900S hold?
The BM3-900S has a maximum rated capacity of 900 lb, which must include the combined weight of all three occupants plus their tools, materials, and personal protective equipment. With a basket weight of about 870 lb, the total suspended load is roughly 1,770 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 BM3-900S?
The BM3-900S is rated for three occupants. Lift planning should allocate the 900 lb capacity across three workers and their equipment, using prudent per-person weight assumptions so that total occupant and tool weight stays within the rated load during operations.
When should the BM3-900S be used instead of the BM3-900G?
Choose the BM3-900S when three-person crews are working under overhead piping, decks, or structural steel and an overhead frame is desired to help manage dropped-object and overhead-contact risks. The BM3-900G is more appropriate where overhead clearance is tight or overhead hazards are minimal and a non-overhead configuration offers more flexibility.
Can the BM3-900S be customized?
Yes. Lifting Technologies can customize the BM3-900S with options such as additional tool or material trays, specific overhead frame details, custom rigging configurations, additional fall protection anchor points, and custom colors or markings for site identification and safety programs. Custom configurations can be developed around project-specific requirements.
What documentation comes with the BM3-900S?
Each BM3-900S 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 training resources can be provided to support regulatory compliance and integration into site safety and maintenance programs.
