SM1-300S Single-Person Square Crane Man Basket With Overhead Protection
Premier Series | Single-Person | Square | With Overhead Protection
Product Description
The SM1-300S is a single-occupant crane-suspended personnel platform with integrated overhead protection, engineered for safe elevated access in confined or restricted work environments where overhead hazards are present. Its 29″ x 29″ square footprint provides an ultra-compact, stable platform that fits into tight spaces inside plants and structures while the square shape maintains a balanced feel in all directions.
Designed to meet or exceed OSHA 1926.1431 requirements for hoisting personnel, the SM1-300S features a high-strength welded square tubular steel frame, 42″ guardrails with 6″ toeboards, an inward-swinging access gate, perforated steel sides from toeboard to mid-rail, and multiple fall protection tie-off points, along with a fixed overhead frame and perforated overhead protection. The 300 lb rated capacity is sized for a single worker with tools and PPE, and the 405 lb basket weight keeps the total suspended load manageable for a wide range of cranes while accounting for the overhead structure.
Like all Lifting Technologies Premier crane man baskets, the SM1-300S is manufactured in Missoula, Montana, and ships as a turnkey package that includes a dedicated four-leg sling assembly, detachable test weight system, and complete documentation. Each unit is proof-load tested at 125% of its rated capacity—375 lb—before leaving the facility, and ships with proof-load certificates, inspection checklists, access to Lifting Technologies online video training, and operator guidelines to support site safety and regulatory compliance.
The SM1-300S is used in power generation, petrochemical, and construction environments where a single technician must work at height under overhead steel, piping, or decks in very tight spaces. Its combination of compact square footprint and overhead protection makes it a strong choice for inspections, small repairs, and punch-list tasks where both confined access and mitigation of dropped-object risk are important.
Industrial Applications
Power Generation & Utilities
Power generation facilities often require single-person access inside crowded boiler rooms, duct runs, and areas with overhead steel where dropped objects and overhead obstructions are concerns. The SM1-300S’s 29″ x 29″ footprint and overhead protection make it well suited for localized boiler inspections, small duct repairs, and instrument maintenance carried out beneath structural members, cable trays, or support steel.
The compact square platform positions a single technician close to equipment in narrow spaces while the overhead frame adds a protective barrier in areas where scale, debris, or small tools could fall from above during outage work.
Petrochemical & Refining
Refineries and petrochemical plants frequently place workers in congested pipe racks and around vessels where overhead piping and structures increase dropped-object risk. The SM1-300S allows a single technician to perform flare line checks, valve adjustments, and instrument calibration from a compact square basket while the overhead protection structure helps manage overhead hazards in tight units and rack bays.
Its 29″ x 29″ footprint fits into narrow pipe rack corridors and tight access points while maintaining an OSHA-compliant guardrail system and overhead coverage for the worker.
Construction & Structural
On construction and structural projects, single-person baskets are used for weld touch-ups, bolt verification, and punch-list work under beams and decks. The SM1-300S provides a protected square platform for a single worker to move under overhead steel, deck panels, or canopies while addressing individual connections, welds, or fasteners.
The ultra-compact 29″ x 29″ footprint helps crews reach tight locations within partially erected structures while the overhead frame offers added protection from minor falling debris during finishing and inspection activities.
Features & Benefits
Compact Square Footprint With Canopy: The 29″ x 29″ square platform fits into confined spaces where larger baskets cannot, offering a balanced footprint and integrated overhead protection for single-person access beneath piping, steel, or decks.
Overhead Protection for Confined Work: The integrated overhead frame with perforated protection panels helps shield the worker from small falling debris and incidental contact with overhead structures, making the SM1-300S ideal for overhead-hazard environments in tight plant and structural spaces.
OSHA-Compliant Premier Construction: Built to comply with OSHA 1926.1431, the SM1-300S includes 42″ guardrails, 6″ toeboards, an inward-swinging gate, perforated sides from toeboard to mid-rail, multiple fall protection anchor points, and a dedicated base-attached suspension system that improves platform stability.
Proof Load Tested to 375 lb: Each SM1-300S is proof-load tested at 375 lb (125% of its 300 lb rated capacity) before shipment and ships with proof-load certificates, inspection documentation, and serial-number traceability to support site safety and regulatory requirements.
Optimized Weight-to-Capacity for Overhead Model: With a 405 lb basket weight and a 300 lb rated capacity, the SM1-300S balances overhead protection and robust construction with a total suspended load that remains manageable for a wide range of cranes and lifting plans.
Frequently Asked Questions
What OSHA regulations apply to the SM1-300S?
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 anchor points, and pre-lift inspections. The SM1-300S is designed and documented to support compliance with these standards, including the overhead protection system.
How much weight can the SM1-300S hold?
The SM1-300S has a maximum rated capacity of 300 lb, which includes the occupant plus tools, materials, and personal protective equipment. With a basket weight of 405 lb, the total suspended load is 705 lb, excluding rigging; each unit is proof-load tested at 375 lb (125% of capacity) prior to shipment.
How many people can work in the SM1-300S?
The SM1-300S is rated for a single occupant. Lift planning should treat this as a one-person platform and ensure that the combined weight of the worker, tools, and PPE does not exceed the 300 lb rated capacity.
When should the SM1-300S be used instead of the SM1-300G or BM1-300S?
The SM1-300S is preferred when a single technician requires the most compact square footprint with overhead protection in extremely tight spaces. The SM1-300G is suited to single-person work without overhead hazards, and the BM1-300S offers a rectangular footprint for added reach along the work face when space allows.
Can the SM1-300S be customized?
Yes. Custom options include additional tool trays, modified overhead frame or gate details, specialized rigging configurations, additional fall protection anchor points, and custom paint colors or markings for site identification. Lifting Technologies can tailor the SM1-300S to specific project and safety requirements.
What documentation comes with the SM1-300S?
Each SM1-300S 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 are available to support regulatory compliance, safety programs, and crew training.
