SEC4-1200 Square Professional Crane Man Basket
Product Description
The SEC4-1200 is the largest square Professional crane man basket from Lifting Technologies, designed for up to four workers plus tools when a spacious square work area is needed without overhead protection. Its 58″ by 58″ platform provides significantly more room than smaller SEC models while retaining the balanced, symmetric footprint that square baskets offer for orientation and positioning under the crane hook.
Professional-series SEC baskets use a high-strength 0.120″ wall, 1.50″ square tubular steel frame with a 19-W-4 bar grating floor to create a robust, slip-resistant work surface. Guarding includes 42″ high guardrails measured from the deck, 6″ high toeboards, and side infill panels from toeboard to mid-rail, typically perforated or expanded metal, to help retain tools and small objects. The platform includes an inward-opening access gate with a positive restraining device, and a full-perimeter inner grab rail that serves as fall-arrest anchorage for personal protective equipment in line with OSHA 1926.502.
The SEC4-1200 suspended personnel platform features a 1,200 lb, four-person maximum rated load capacity with an estimated platform (basket) weight of 585 lb. The 1,200 lb rating is intended for four occupants plus tools, materials, and PPE combined.
The suspension system consists of a four-leg sling assembly of 1/2″ 6×36 IWRC wire rope attached to a master link for the crane hook. Each leg is connected to the platform base via threaded steel safety clevis pins and swaged terminations, forming a base-attached sling arrangement that supports stable, evenly distributed lifting. A fifth safety leg is included to tie off to the load line above the overhaul ball, enhancing stability and aligning with OSHA 29 CFR 1926.1431 for hoisting personnel.
Each SEC4-1200 is proof-load tested at 1,500 lb—125% of its 1,200 lb rated capacity—and is supplied with Lifting Technologies’ detachable Test Weight System, sling assembly, and documentation. Professional baskets include the unique detachable test weights, electrostatic powder-coat finish in red (with safety yellow for the test weight system), proof-load certificates, and inspection checklists, access to Lifting Technologies online video training, plus the Use and Safety Handbook to guide proper operation and inspection.
SEC4-1200 is used for construction, industrial, and infrastructure work where four-person crews must share a crane-suspended work area, and where open-top access, visibility, and vertical reach are more important than having an integrated overhead frame. It offers a large square workspace while still being easier to position than long rectangular platforms in some layouts.
Industrial Applications
Construction & Structural
On building and structural steel projects, SEC4-1200 provides a roomy square platform for four-person crews performing tasks such as joint inspection, multi-worker bolting or welding operations, and finishing work along beams, columns, or platform edges. The 58″ × 58″ footprint offers ample room for personnel and tools while maintaining a manageable plan size for positioning beneath structural framing.
Because it is open-top, SEC4-1200 is best suited for zones where overhead falling-object hazards are limited or controlled through work planning, tool tethering, and other site measures, leaving the crew free to reach upward without interference from an overhead structure.
Industrial Plants & Maintenance
In industrial facilities, SEC4-1200 supports four-technician tasks where multiple trades need simultaneous access—for example, equipment replacements, larger platform-edge work, or pipe and cable installation requiring coordinated mechanical and electrical work. The large square floor area gives space for personnel and equipment while still fitting into many plant access clearances.
Perforated side infill and toeboards help reduce dropped-object risk around the basket, and the full-perimeter grab rail allows multiple lanyard connections as part of plant fall-protection programs.
Utilities & Infrastructure
For utilities and infrastructure, SEC4-1200 is suitable for group work at discrete locations—such as bridge access points, parapet segments, or structural nodes—where a four-person crew must be present in the basket at once rather than spread along a long line. The square platform concentrates the crew in a single, stable workspace under the crane.
Open-top access is useful where overhead clearances are tight or where vertical reach is important, assuming overhead hazards are controlled via project-specific traffic management and dropped-object controls.
Features & Benefits
Spacious Four-Person Square Work Area: The 58″ × 58″ open-top square platform provides a generous work area for up to four workers plus tools and materials, balancing crew capacity with a compact, symmetric footprint for positioning.
Professional-Series, OSHA-Aligned Construction: SEC4-1200 uses 0.120″ wall, 1.50″ square steel tubing, 19-W-4 bar grating floor, 42″ guardrails, 6″ toeboards, side enclosure from toeboard to mid-rail, an inward-opening access gate, and a full-perimeter inner grab rail, aligning with OSHA 1926.502 requirements for guardrails, toeboards, and anchorage.
Base-Attached Four-Leg Sling System With Safety Leg: A four-leg 1/2″ 6×36 IWRC wire rope sling assembly attached to base pad eyes with threaded safety clevis pins, plus a fifth leg to the load line above the overhaul ball, delivers stable, OSHA 1926.1431–compliant hoisting support for suspended personnel.
125% Proof-Load Tested With Detachable Test Weight System: Each SEC4-1200 is proof-tested at 1,500 lb (125% of the 1,200 lb rating) and includes Lifting Technologies’ detachable Test Weight System, proof-test certificates, and inspection documentation for commissioning and periodic inspections.
Durable Powder-Coat Finish and Customization: Professional baskets feature an electrostatic powder-coat finish in red, with safety-yellow test weight system, for impact and corrosion resistance; custom colors and certain configuration options are available to meet project or corporate standards.
Frequently Asked Questions

The SEC4-1200 is 58" wide by 58" long square platform, with a maximum rated load capacity of 1,200 lb (four persons plus tools), a 1,500 lb proof-test weight, and an estimated basket weight of about 585 lb.
How many people can SEC4-1200 carry?
SEC4-1200 is rated for four occupants, provided the combined weight of personnel, tools, materials, and PPE does not exceed the 1,200 lb rated load capacity.
Does SEC4-1200 have overhead protection?
No. SEC4-1200 is an open-top Square Professional model; the square Professional overhead-protected baskets are designated SECO-series, such as SECO4-1200.
Which OSHA standards does SEC4-1200 support?
SEC4-1200 is built in compliance with OSHA 29 CFR 1926.1431 for hoisting personnel and OSHA 1926.502 Subpart M for fall protection, with proof-load testing at 125% of rated capacity and guardrail, toeboard, and anchorage provisions aligned to these rules.
What is included with SEC4-1200?
SEC4-1200 orders include the platform, four-leg sling assembly with safety leg, detachable 1,500 lb test weight system, full-perimeter inner grab rail, side enclosure, powder-coat finish, Use and Safety Handbook and training materials, proof-load test certificate, and inspection checklist.
When is SEC4-1200 preferred over smaller SEC models or SECO4-1200?
SEC4-1200 is chosen when four-person crews require a larger square, open-top platform and overhead hazards are limited or controlled; smaller SEC models (SEC1-300, SEC2-600, SEC3-900) fit smaller crew sizes, and SECO4-1200 is used when the same or similar capacity and plan size are needed with integrated overhead protection.
