RM1-300S/26 Single-Person Round Crane Man Basket With Overhead Protection
Product Description
The RM1-300S/26 is a single-occupant crane-suspended personnel platform with integrated overhead protection, engineered for elevated work in extremely confined, overhead‑hazard locations around towers, stacks, tanks, and other cylindrical structures. Its 26″ round footprint minimizes size while still providing an efficient workspace, allowing a single worker to position close to curved surfaces and pass through narrow clearances where larger platforms cannot fit.
Designed to meet or exceed OSHA 1926.1431 requirements for hoisting personnel, the RM1-300S/26 features a heavy-gauge steel frame and floor grating, a high-strength round tubular steel frame, 42″ guardrails with 6″ toeboards, perforated steel sides from toeboard to mid-rail, and a fixed overhead frame with perforated steel skylights approximately 79″ above the floor. The 300 lb rated capacity is intended for a single worker plus tools and PPE, and the 355 lb basket weight provides robust construction and canopy protection while keeping the total suspended load low enough for smaller cranes and constrained lift plans.
As part of the Premier round man basket line, the RM1-300S/26 ships as a turnkey package that includes a dedicated base-attached suspension system with a four-leg sling assembly of 1/2″ 6×36 IWRC wire rope secured to a master link and attached to the platform base with swage sockets and safety-threaded clevis pins, plus a safety leg for tie-off to the load line above the overhaul ball. Each basket incorporates Lifting Technologies’ unique easy-on/easy-off detachable test weight system, is proof-load tested at 375 lb—125% of its 300 lb rated capacity—before shipment, and ships with proof-load certificates, inspection checklists, access to Lifting Technologies online video training, and operator guidelines to support safety programs and regulatory compliance.
The RM1-300S/26 is commonly used in power generation, petrochemical, and construction environments where a single technician must work at height in very tight spaces under overhead hazards. Its ultra-compact round footprint, overhead protection, and OSHA-compliant design make it well suited for inspections, small repairs, and punch-list work on small-diameter stacks, columns, towers, and other curved structures in congested areas.
Industrial Applications
Power Generation & Utilities
Power generation facilities rely on compact personnel platforms for access to small stacks, towers, and curved duct sections where space is restricted and overhead obstructions are common. The RM1-300S/26’s 26″ round footprint and overhead protection make it ideal for single-technician stack inspections, localized duct repairs, and work on small tower appurtenances where only one worker needs to be at elevation.
The ultra-compact round basket can be rotated around cylindrical structures to provide 360-degree access in confined spaces, while the overhead frame helps shield the worker from scale or minor debris that may fall from above during outage work.
Petrochemical & Refining
Refineries and petrochemical plants often require precise access to small columns, tower nozzles, and fittings in congested process units where piping and structural steel severely limit clearances. The RM1-300S/26 supports single-person external inspections, nozzle checks, and localized maintenance on compact cylindrical equipment where a 26″ round diameter is needed to clear surrounding lines and steel while maintaining overhead protection.
Its integrated canopy helps reduce exposure to minor falling debris from overhead piping, trays, or supports, making it appropriate for dense process areas where one technician needs safe, highly targeted access at height.
Construction & Structural
On construction and structural projects involving small-diameter towers, chimneys, masts, or curved architectural elements, the RM1-300S/26 provides a protected single-person platform for weld touch-ups, bolt checks, and punch-list work. The 26″ round footprint lets the basket reach tight locations under and around small circular or curved elements where larger platforms cannot maneuver, especially beneath overhead beams or decks.
The round shape allows the platform to follow the curvature of the workpiece, while the overhead frame adds protection from minor falling debris and materials on active construction sites.
Features & Benefits
Ultra-Compact Round Footprint With Canopy
The 26″ round platform minimizes overall size for access into extremely tight spaces while providing an efficient workspace and integrated overhead protection for a single worker around small towers, stacks, and vessels.
Optimized for Small Cylindrical Structures
The round footprint eliminates corners and is sized specifically for work on small-diameter columns and stacks, allowing the basket to rotate around curved surfaces and maintain close, consistent positioning along the circumference.
OSHA-Compliant Premier Construction
Built to comply with OSHA 1926.1431, the RM1-300S/26 includes a dedicated base-attached suspension system that minimizes tipping, 42″ guardrails, 6″ toeboards, perforated side panels from toeboard to mid-rail, and a grab rail inside the entire perimeter providing personal fall arrest anchorage in compliance with OSHA 1926.502. Overhead protection panels with perforated skylights are positioned approximately 79″ above the floor.
Proof Load Tested to 375 lb
Each RM1-300S/26 is proof-load tested at 375 lb (125% of its 300 lb rated capacity) prior to shipment and includes Lifting Technologies’ easy-on/easy-off detachable test weight system, proof-load certificates, and inspection documentation for safety and audit readiness.
Lightweight, Protective Design
With a 355 lb basket weight and a 300 lb capacity, the RM1-300S/26 combines overhead protection and robust construction with a relatively low total suspended load, making it suitable for use with smaller cranes and constrained lift plans.
Frequently Asked Questions
What OSHA regulations apply to the RM1-300S/26?
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 inspection procedures. The RM1-300S/26 is designed and documented to support compliance with these standards, including its overhead protection system.
How much weight can the RM1-300S/26 hold?
The RM1-300S/26 has a maximum rated capacity of 300 lb, which must include the worker plus tools, materials, and personal protective equipment. With a basket weight of 355 lb, the total suspended load is approximately 655 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 RM1-300S/26?
The RM1-300S/26 is rated for one occupant. Lift planning should treat it as a single-person platform and ensure the combined weight of the worker, tools, and PPE remains within the 300 lb rated capacity.
When should the RM1-300S/26 be used instead of other round models?
The RM1-300S/26 is best when only one technician is required and access is extremely tight around small cylindrical structures with overhead hazards, but a full 300 lb capacity is desired. Other round overhead models such as RM1-250S/26, RM1-250S/32, RM1-300S/32, RM2-600S/38, RM3-900S/48, and RM4-1200S/60 are better suited when different capacities, diameters, or additional occupants are needed.
Can the RM1-300S/26 be customized?
Yes. Lifting Technologies can customize the RM1-300S/26 with options such as an inward-opening access gate with positive restraining device, additional tool trays, specialized rigging configurations, additional fall protection anchor points, and custom paint colors or markings for site identification. Custom-designed platforms of other sizes and shapes are also available.
What documentation comes with the RM1-300S/26?
Each RM1-300S/26 ships with proof-load test certification, operator guidelines, pre-use inspection checklists, access to Lifting Technologies online video training, and detailed product specifications, along with access to a use and safety handbook and training video explaining the applicable OSHA rules. Additional documentation can be provided to support regulatory compliance and site safety programs.
