ERM4-1200/60 Round Professional Man Basket (Open-Top, Slings)
Product Description
ERM4-1200/60 (Slings) is the larger-capacity round Professional crane man basket in Lifting Technologies’ suspended personnel platform line, designed for up to four workers plus tools when a 60″ diameter circular work area and open-top configuration are desired. The round shape minimizes plan size for a given area while providing a centralized workspace around the crane hook for multi-person access to overhead or surrounding work.
Professional Round Man Basket features include a heavy-gauge steel frame and floor grating to create a durable, slip-resistant platform, 42″ high guardrails measured from the floor, a full-perimeter inner grab rail for personal fall-arrest anchorage, 6″ high toeboards, and perforated steel plate side panels from toeboard to mid-rail to help contain tools and small materials. An inward-opening access gate with a positive restraining device controls entry and exit. Unlike overhead-protected ERMO models, ERM4-1200/60 is an open-top design with no overhead frame or skylight panels, reducing weight and overall height.
The ERM4-1200/60 (Slings) features a 60″ diameter, a 1,200 lb maximum rated load capacity, 1,500 lb test(weight), and a 530 lb basket weight. These values indicate that four workers plus their tools, materials, and PPE can be carried as long as the combined live load does not exceed 1,200 lb, and that each platform is proof-load tested at 125% of rated capacity (1,500 lb) prior to being placed in service.
ERM-series sling models use a dedicated, base-attached four-leg sling assembly made from 1/2″ 6×36 IWRC wire rope, secured to a master link that connects to the crane hook. Each sling leg is attached to the platform base using swaged terminations and threaded safety clevis pins, forming a base-attached hoisting system that helps minimize platform tipping and promotes even load distribution. A fifth safety leg is provided to tie off to the load line above the overhaul ball, further stabilizing the platform and aligning with OSHA 29 CFR 1926.1431 guidance for hoisting personnel.
Professional round baskets, including ERM4-1200/60, are finished in an electrostatic powder-coat in solid red (standard) for the platform with the detachable Test Weight System components in yellow, providing high resistance to impact, abrasions, chemicals, and corrosion. Lifting Technologies’ unique easy-on/easy-off detachable Test Weight System allows convenient proof-load testing in the field; each ERM4-1200/60 ships with this system, the sling assembly, Use and Safety Handbook, proof-load certificates, and inspection checklists, supplying the equipment and documentation required for safe commissioning and periodic checks.
ERM4-1200/60 is chosen when a four-person crew needs a compact circular platform for work that surrounds the hook—such as overhead or radial tasks—without needing integrated overhead protection, relying instead on project controls to manage overhead hazards while benefiting from the round platform’s efficient footprint and flexibility.
Industrial Applications
Construction & Structural
On construction and structural projects, ERM4-1200/60 supports four-person crews performing overhead or radial work such as inspection, minor repairs, or installation where the team benefits from standing around a central point under the crane hook. The 60″ diameter gives more room than 48″ round models while still being compact relative to equivalent rectangular areas.
The open-top configuration is used where overhead falling-object risks are minimized or controlled via work sequencing, tool tethering, and restricted overhead activity, allowing unimpeded upward reach and visibility for four workers.
Industrial Plants & Maintenance
In industrial plants, refineries, and process facilities, ERM4-1200/60 is suited to multi-person maintenance or inspection tasks around vessels, large piping, or structural nodes where 360-degree access is required. The round platform allows the crew to rotate the basket and move around the perimeter to reach different parts of the equipment or structure without frequent repositioning.
Perforated side panels and 4″ toeboards reduce the risk of dropped tools and small components, while the full-perimeter inner grab rail provides attachment points for four harnesses, aligning with plant fall-protection policies.
Utilities & Infrastructure
For utilities and infrastructure, ERM4-1200/60 can be used under bridges, towers, or gantries where crews must work around central features such as piers, cables, or attachments. The 60″ round footprint can fit within many structural openings and underneath key locations, allowing four-person teams to perform inspection and repair tasks efficiently.
Its open-top design assumes overhead hazards are controlled through traffic restrictions, no-work zones above the basket, and dropped-object prevention measures, rather than through integrated overhead framework.
Features & Benefits
Spacious Four-Person Round Work Area: The 60″ diameter open-top round platform provides a centralized workspace for up to four workers plus tools, allowing 360-degree access around a central work point while keeping a compact footprint.
Professional-Series Construction and OSHA Alignment: ERM4-1200/60 uses heavy-gauge steel frame and bar grating floor, 42″ guardrails, 6″ toeboards, perforated side panels, an inward-opening access gate, and a full-perimeter inner grab rail, aligning with OSHA 1926.502 Subpart M fall-protection practices.
Dedicated Base-Attached Four-Leg Sling Assembly With Safety Leg: A four-leg 1/2″ 6×36 IWRC wire rope sling attached to the base, plus a safety leg to the load line above the overhaul ball, provides stable hoisting and minimizes tipping in accordance with OSHA 1926.1431 recommendations for suspended personnel platforms.
125% Proof-Load Tested With Detachable Test Weight System: Each ERM4-1200/60 is proof-tested at 1,500 lb (125% of its 1,200 lb rating) and is covered by the Professional round line’s unique detachable Test Weight System, with proof-load certificates and inspection documentation supplied.
Durable Powder-Coat Finish and Custom Options: Professional round baskets are powder-coat finished in red with yellow test weights for durability and visibility; custom colors and configurations are available, and overhead protection can be added by specifying the ERMO4-1200/60 overhead model instead.
Frequently Asked Questions
What are the ERM4-1200/60 dimensions and ratings?
ERM4-1200/60 (Slings) features 60" diameter, 1,200 lb maximum rated load capacity, a 1,500 lb test (proof) weight, and a 530 lb basket weight.
How many people can ERM4-1200/60 carry?
ERM4-1200/60 is designed for four occupants, provided the combined weight of personnel, tools, materials, and PPE does not exceed the 1,200 lb rated capacity.
Does ERM4-1200/60 have overhead protection?
No. ERM4-1200/60 is an open-top Round Professional model; ERMO4-1200/60 is the corresponding overhead-protected round model with an overhead frame and perforated skylights and a higher basket weight.
Which OSHA standards does ERM4-1200/60 support?
ERM4-1200/60 is designed around OSHA 29 CFR 1926.1431 for hoisting personnel and OSHA 1926.502 Subpart M for fall protection, including guardrails, toeboards, side enclosure, anchorage, and proof-load testing at 125% of rated capacity.
What is typically included with an ERM4-1200/60 order?
Professional round baskets ship with the platform, base-attached four-leg sling assembly with safety leg, detachable Test Weight System, data plate, Use and Safety Handbook/training materials, proof-load test certificate, and inspection checklist.
When would ERM4-1200/60 be chosen over ERM3-900/48 or ERMO4-1200/60?
ERM4-1200/60 is selected when a four-person crew needs a larger 60" round open-top platform and overhead hazards are controlled administratively; ERM3-900/48 suits three-person crews on a 48" round, and ERMO4-1200/60 is used when the same 60" diameter and capacity are required with integrated overhead protection.
