SM3-900G 3-Person Square Crane Man Basket
Premier Series | Three-Person | Square | No Overhead Protection
Product Description
The SM3-900G is a three-occupant crane-suspended personnel platform designed for crew-based maintenance, inspection, and construction tasks where multiple workers need to operate together at height. Its 48″ x 48″ square footprint provides generous shared workspace while maintaining a compact enough size to maneuver between structural members, plant equipment, and access openings.
Built to meet or exceed OSHA 1926.1431 requirements for hoisting personnel, the SM3-900G features a high-strength welded steel frame, 42″ guardrails with 6″ toeboards, an inward-swinging access gate, perforated sides from toeboard to mid-rail, and multiple fall protection tie-off points. The 900 lb rated capacity accommodates a three-person crew with tools and materials, and the approximately 530 lb basket weight keeps the total suspended load within the lifting range of many construction and industrial cranes.
Like all Lifting Technologies Premier crane man baskets, the SM3-900G is manufactured in Missoula, Montana, and ships with a dedicated four-leg sling assembly, patented detachable test weight system, and complete documentation. Each unit is proof-load tested to 125% of its rated capacity—1,125 lb—before leaving the facility, and ships with proof-load certification, inspection checklists, access to Lifting Technologies online video training, and operator guidelines to support safety programs and regulatory compliance.
The SM3-900G is widely used in power generation, petrochemical, and construction applications where a three-person crew can significantly improve productivity compared with single- or two-person baskets. Its square footprint offers a stable, balanced working area for crews performing coordinated tasks such as connection work, inspections, light repairs, and finishing activities at height.
Industrial Applications
Power Generation & Utilities
Power generation facilities depend on crew-sized platforms for major outage work on boilers, ducts, precipitators, and structural steel where multiple technicians must work together at elevation. The SM3-900G’s 3-person, 900 lb configuration and 48″ x 48″ square deck support crew-based boiler waterwall repairs, ductwork maintenance, and structural inspection tasks around large equipment where a stable, shared workspace is essential.
The square footprint provides a balanced platform for three workers with welding equipment, NDT tools, or mechanical repair gear, helping plants cover more work per lift without stepping up to the larger four-person basket.
Petrochemical & Refining
Refineries and petrochemical plants use personnel platforms for turnaround work on reactors, columns, and pipe racks where multi-worker coordination is required. The SM3-900G allows three-person crews to execute tasks such as large vessel externals inspections, coordinated piping repairs, and rack maintenance where a compact but spacious square basket is more practical than a long rectangular footprint.
Its 48″ x 48″ deck offers sufficient space for crew members, tools, and test equipment while fitting through many structural openings and pipe rack bays, making it a strong option for dense process units.
Construction & Structural
Construction projects use crew-sized crane baskets for steel erection, retrofit work, bridge and overpass projects, and structural finishing where multiple workers must operate together at height. The SM3-900G gives three-person crews a stable square platform for connection work, bracing installation, and punch-list activities on building frames, bridges, and industrial structures.
The 48″ x 48″ footprint balances workspace and maneuverability, allowing crews to position close to their work while staging tools, fasteners, and repair materials on the deck.
Features & Benefits
Crew-Sized Square Work Platform
The 48″ x 48″ deck provides ample room for three workers, tools, and materials, giving crews a shared workspace that remains compact enough for typical plant and structural layouts.
Stable, Balanced Footprint for Crews
The square platform offers a balanced footprint that enhances stability and worker comfort, ideal for three-person inspection, repair, and construction tasks where crews need to face multiple directions without long overhangs.
OSHA-Compliant Premier Construction
Designed to comply with OSHA 1926.1431, the SM3-900G includes 42″ guardrails, 6″ toeboards, an inward-swinging gate, perforated steel sides from toeboard to mid-rail, multiple fall protection anchor points, and a dedicated base-attached suspension system to minimize tipping.
Proof Load Tested to 1,125 lb
Each SM3-900G is proof-load tested at 1,125 lb (125% of its 900 lb rated capacity) before shipment and ships with proof-load test certificates, inspection documentation, and serial-number traceability for safety and audit records.
Robust Weight-to-Capacity Ratio
With an approximate basket weight of 530 lb and a 900 lb rated capacity, the SM3-900G delivers a robust structure and crew rating while keeping total suspended load compatible with a wide range of cranes and rigging setups.
Frequently Asked Questions
Q: What OSHA regulations apply to the SM3-900G?
A: OSHA 1926.1431 governs the use of crane-suspended personnel platforms in construction, including requirements for proof-load testing, guardrail and toeboard geometry, fall protection anchor points, and inspection procedures. The SM3-900G is engineered and documented to support compliance with this standard.
Q: How much weight can the SM3-900G hold?
A: The SM3-900G has a maximum rated capacity of 900 lb, which includes the combined weight of all three occupants, plus their tools, materials, and personal protective equipment. With a basket weight of about 530 lb, the total suspended load is approximately 1,430 lb, excluding rigging; each unit is proof-load tested at 1,125 lb (125% of capacity) prior to shipment.
Q: How many people can work in the SM3-900G?
A: The SM3-900G is rated for three occupants. Lift planning should allocate the 900 lb capacity across three workers and their equipment, using conservative per-person weight allocations so that total occupant and tool weight remains within the rated load.
Q: When should the SM3-900G be used instead of the SM2-600G or SM4-1200G?
A: Use the SM3-900G when tasks require a three-person crew and a larger shared workspace than the SM2-600G, but a full four-person basket is not necessary. The SM2-600G suits two-worker tasks in tighter spaces, while the SM4-1200G is best for full crews and heavier workloads.
Q: Can the SM3-900G be customized?
A: Yes. Typical custom options include additional tool or material trays, alternate gate or rail configurations, specialized rigging arrangements, additional fall protection anchor points, and custom paint colors or markings for site identification. Custom designs can be developed around project-specific requirements.
Q: What documentation comes with the SM3-900G?
A: Each SM3-900G 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 training resources can be provided to support regulatory compliance, safety programs, and crew training.
