RM4-1200G/60 4-Person Round Crane Man Basket
Premier Series | Four-Person | Round | No Overhead Protection
Product Description
The RM4-1200G/60 is a four-occupant crane-suspended personnel platform designed for large crews working on towers, tanks, stacks, silos, and other cylindrical or curved structures where full-circle access is required. Its 60″ round footprint provides a spacious, efficient workspace that allows up to four workers to position themselves around the perimeter with 360-degree access to the work face.
Built to meet or exceed OSHA 1926.1431 requirements for hoisting personnel, the RM4-1200G/60 features a heavy-gauge steel frame and floor grating, a high-strength round tubular steel frame, 42″ guardrails with 6″ toeboards, perforated steel side panels from toeboard to mid-rail, and a dedicated base-attached suspension system that minimizes tipping. A four-leg 1/2″ 6×36 IWRC wire rope sling assembly attaches to the platform base, and a grab rail inside the entire perimeter provides personal fall arrest anchorage in compliance with OSHA 1926.502. The 1,200 lb rated capacity accommodates a four-person crew with tools and light materials, while the 560 lb basket weight keeps the total suspended load compatible with many industrial cranes.
Like all Lifting Technologies Premier round man baskets, the RM4-1200G/60 is manufactured in Missoula, Montana, and ships as a turnkey package including the sling assembly, a safety leg for tie-off to the load line above the overhaul ball, and Lifting Technologies’ easy-on/easy-off detachable test weight system. Each unit is proof-load tested at 1,500 lb—125% of its 1,200 lb rated capacity—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 RM4-1200G/60 is widely used in power generation, construction, and mining or heavy industrial environments where four-person crews perform installation, repair, and inspection work at height around large cylindrical equipment. Its large, round workspace makes it especially useful for major work scopes on towers, tanks, and large process vessels where multiple workers must coordinate tasks around the circumference in a single lift.
Industrial Applications
Power Generation & Utilities
Power generation facilities often require crew-sized platforms for major outage work on stacks, towers, tanks, and curved duct systems where the work follows a circular profile. The RM4-1200G/60’s 60″ round deck and 1,200 lb capacity support four-person crews performing stack inspections, casing and duct repairs, and tower-related maintenance where 360-degree access around the structure improves coverage and efficiency.
The large, round workspace allows workers to position around the perimeter with welding, NDT, or mechanical repair equipment, letting crews address multiple locations along the circumference from a single lift.
Construction & Structural
Large construction and structural projects—such as tanks, silos, chimneys, towers, and curved architectural or bridge elements—benefit from crew-sized round man baskets for steel erection, inspection, and finishing tasks. The RM4-1200G/60 provides a four-person round platform for structural crews handling welds, connections, sealing, and punch-list work along curved faces where rectangular or square baskets are harder to align to the structure.
The 60″ diameter deck offers a broad, stable workspace for multiple workers, tools, and small components while enabling the basket to rotate around the structure for continuous access to the work zone.
Mining & Heavy Industry
Mining operations and heavy industrial facilities rely on rugged man baskets for maintenance on large cylindrical process vessels, bins, kilns, and similar equipment. The RM4-1200G/60 supports four-person crews performing maintenance and repair on large tanks, processing shells, and tall cylindrical structures where the round footprint fits the equipment profile and allows crews to work around the circumference.
Its heavy-duty construction and high capacity make it suitable for demanding environments where crews must bring a significant amount of tools and small parts along the perimeter of large machines or structures during intensive maintenance outages.
Features & Benefits
Full-Crew Round Work Platform: The 60″ round deck provides a spacious, efficient work area for up to four workers, tools, and materials, enabling crews to position around cylindrical and curved structures with 360-degree access.
Optimized for Large Cylindrical Structures: The round footprint eliminates corners that can interfere with towers, tanks, stacks, and other circular equipment, making the RM4-1200G/60 ideal for large-diameter structures where aligning the basket around the curvature is essential.
OSHA-Compliant Premier Construction: Built to comply with OSHA 1926.1431, the RM4-1200G/60 includes a dedicated base-attached suspension system that minimizes tipping, 42″ guardrails, 6″ toeboards, perforated side panels from toeboard to mid-rail, an access gate with positive restraining device, and a perimeter grab rail providing fall arrest anchorage in compliance with OSHA 1926.502.
Proof Load Tested to 1,500 lb: Each RM4-1200G/60 is proof-load tested at 1,500 lb (125% of its 1,200 lb rated capacity) prior to shipment and ships with the detachable test weight system, proof-load certificates, and inspection documentation for safety and audit readiness.
Robust Weight-to-Capacity Ratio for Demanding Projects: With a 560 lb basket weight and a 1,200 lb capacity, the RM4-1200G/60 offers heavy-duty construction suitable for demanding industrial work while keeping the overall suspended load compatible with many cranes and rigging configurations.
Frequently Asked Questions
What OSHA regulations apply to the RM4-1200G/60?
OSHA 1926.1431 governs the use of crane-suspended personnel platforms in construction, defining requirements for proof-load testing, guardrail and toeboard dimensions, fall protection anchor points, and inspection procedures. The RM4-1200G/60 is designed and documented to help users comply with these standards.
How much weight can the RM4-1200G/60 hold?
The RM4-1200G/60 has a maximum rated capacity of 1,200 lb, which includes the combined weight of all four occupants plus tools, materials, and personal protective equipment. With a basket weight of 560 lb, the total suspended load is approximately 1,760 lb, excluding rigging; every unit is proof-load tested at 1,500 lb (125% of capacity) before shipment.
How many people can work in the RM4-1200G/60?
The RM4-1200G/60 is rated for four occupants. Lift planning should distribute the 1,200 lb capacity across four workers and their equipment, using conservative per-person weight allocations so that total crew, tools, and PPE remain within the rated load.
When should the RM4-1200G/60 be used instead of smaller round models?
Choose the RM4-1200G/60 when tasks require a full four-person crew and extra workspace around large cylindrical structures—such as major stack or tank work, large-vessel maintenance, or curved structural projects. Smaller models like RM2-600G/38 and RM3-900G/48 are better suited when fewer workers are needed or the work envelope is tighter.
Can the RM4-1200G/60 be customized?
Yes. Lifting Technologies can customize the RM4-1200G/60 with options including modified gate configurations, additional tool or material trays, specialized rigging arrangements, additional fall protection anchor points, and custom paint colors or markings for site or corporate identification. Overhead protection can be added by moving to the RM4-1200S/60 model.
What documentation comes with the RM4-1200G/60?
Each RM4-1200G/60 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, site safety programs, and crew training.
