BM4-1200G 4-Person Rectangular Crane Man Basket
Premier Series | Four-Person | Rectangular | No Overhead Protection
Product Description
The BM4-1200G is a four-occupant crane-suspended personnel platform engineered for large-scale industrial maintenance and outage work where full crew access at height is essential. Its 36″ x 108″ rectangular footprint offers extensive reach along structural members, pipe racks, and bridge girders while maintaining a narrow width that can still navigate between columns, bracing, and process equipment.
Designed to meet or exceed OSHA 1926.1431 requirements, the BM4-1200G features all-welded steel construction, 42″ guardrails with 6″ toeboards, an inward-swinging access gate, and multiple fall protection anchor points to support up to four workers safely at elevation. With a 1,200 lb rated capacity and an approximate basket weight of 805 lb, the BM4-1200G combines robust strength with a predictable suspended load for lift planning on heavy industrial projects.
Like all Lifting Technologies Premier crane man baskets, the BM4-1200G is manufactured in Missoula, Montana, and ships with complete documentation, including proof-load test certificates, inspection checklists, access to Lifting Technologies online video training, and operator guidelines. Each unit is proof-load tested at 1,500 lb—125% of its rated 1,200 lb capacity—before leaving the facility, providing traceable verification that the platform is ready for personnel lifting in demanding work environments.
The BM4-1200G is commonly deployed in power generation, petrochemical, and heavy construction projects where four-person crews perform installation, repair, and inspection tasks along extended work faces. The long rectangular deck gives teams the ability to stage tools, parts, and consumables so they can work multiple joints or locations per lift, significantly reducing crane moves and outage time.
Industrial Applications
Power Generation & Utilities
Large power generation outages often require full crews working together on boilers, precipitators, ducts, and surrounding structures. The BM4-1200G’s 4-person, 1,200 lb configuration supports major boiler panel replacement, large duct section repairs, and extensive structural reinforcement along long runs of steel, giving crews room to work with weld equipment, NDT tools, and consumables.
Construction & Structural
Construction projects—especially bridges, stadiums, and large industrial buildings—use crew-size platforms for steel erection, retrofit work, and structural finishing. The BM4-1200G’s 36″ x 108″ footprint gives four-person teams the capacity and workspace they need for steel erection crews, bridge deck work, and multi-trade tasks where several workers must be at elevation along a long structural member.
Mining & Heavy Industry
Mining operations and heavy industrial facilities depend on rugged personnel platforms for dragline maintenance, shovel repairs, crusher access, and conveyor work in demanding environments. The BM4-1200G supports four-person crews performing dragline boom work, shovel dipper repairs, and mill maintenance where extended reach and high capacity are needed to support workers, tools, and heavier components.
Features & Benefits
Full-Crew Work Platform: The 36″ x 108″ deck is sized for up to four workers plus tools and materials, enabling crew-based outage and construction work where multiple tradespeople must operate together at height.
Maximum Rectangular Reach: The long rectangular footprint delivers extensive reach along beams, pipe racks, bridge girders, and building frames, minimizing crane repositioning and improving productivity on linear work scopes.
OSHA-Compliant Premier Construction: Built to comply with OSHA 1926.1431 for crane-suspended personnel platforms, the BM4-1200G includes 42″ guardrails, 6″ toeboards, an inward-swinging gate, and multiple personal fall arrest anchor points to support four workers with 100% tie-off.
Proof Load Tested to 1,500 lb: Each BM4-1200G is proof-load tested at 1,500 lb (125% of its 1,200 lb rated capacity) before shipment and ships with test certificates, inspection records, and serial-number traceability to support site safety and regulatory audits.
Heavy-Duty Weight-to-Capacity Balance: With an approximate basket weight of 805 lb and a 1,200 lb rated capacity, the BM4-1200G offers a robust structure for demanding industrial environments while keeping total suspended load predictable for crane selection and lift planning.
Frequently Asked Questions
What OSHA regulations apply to the BM4-1200G?
OSHA 1926.1431 governs the use of personnel platforms suspended from cranes in construction, specifying proof-load testing, guardrail and toeboard dimensions, fall protection anchors, and inspection procedures. The BM4-1200G is engineered, tested, and documented to support compliance with its requirements.
How much weight can the BM4-1200G hold?
The BM4-1200G has a maximum rated capacity of 1,200 lb, which includes the combined weight of all four occupants plus their tools, materials, and personal protective equipment. With a basket weight of roughly 805 lb, the total suspended load is approximately 2,005 lb, excluding rigging; each platform is proof-load tested at 1,500 lb (125% of capacity) before shipment.
How many people can work in the BM4-1200G?
The BM4-1200G is rated for four occupants. Lift planning should divide the 1,200 lb capacity across four workers and their tools, using prudent per-person weight assumptions so that total occupant and equipment weight remains within the rated load during operations.
When is a four-person rectangular basket preferred over smaller models?
A four-person rectangular basket like the BM4-1200G is best for large-scale tasks where multiple trades or roles must be present at height, such as coordinated welding and inspection, handling larger components, or covering long sections of structure in a single lift. Smaller one-, two-, or three-person models are better suited for more confined spaces or when fewer workers are required.
Can the BM4-1200G be customized?
Yes. Lifting Technologies can customize the BM4-1200G with options such as modified guardrail height, additional tool and material storage, specialized rigging configurations, additional fall protection anchor points, and custom paint colors or markings for site identification and safety programs. These customizations can be tailored to specific project or regulatory requirements.
What documentation is provided with the BM4-1200G?
Each BM4-1200G 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 resources are available on request to help integrate the platform into site safety, training, and compliance processes.
