Sumner R-250 Roust A Bout Lift

Description

Hoist heavy industrial valves into pipe racks using the Sumner R-250 Roust A Bout Lift. This manual dual-winch lifter handles 1,500 lbs payloads up to 25ft elevation heights across refinery turnarounds. An articulating boom reaches forward over stationary obstacles. Field crews must break the tall mast down into separate sections for transport on standard flatbed trailers.

Heavy-wall square steel tubing forms the welded base and telescoping mast stages to prevent structural twist. Two separate dual-speed manual winches manage vertical mast lift and horizontal boom travel via galvanized aircraft-grade steel cables. Staging dimensions span 62in long by 32in wide with fold-out stabilizers extending outward to 74in. Total bare machine weight sits at 345 lbs without accessories.

Key Features of Sumner 780303

Process plant pipefitters buy Sumner 780303 hoists to install heavy cast steel flanges and pre-welded spools inside congested units. Direct trade pricing provides substantial capital savings over hiring hydraulic mobile crane contractors.

• Rated lift capacity handles 1,500 lbs to lift heavy valves, structural beams, and schedule 80 steel pipe.
• Maximum vertical hook reach hits 25ft to access high overhead mechanical pipe bridges.
• Independent horizontal boom travel extends out to 40in to place loads over building obstacles.
• Dual manual winches isolate vertical mast elevation from horizontal boom positioning.
• Two-speed hand winch gearing enables rapid slack cable retrieval or high-torque load elevation.
• Durable 8in polyurethane-tread steel casters roll across rough concrete floors without binding.
• Mast structure breaks down into separate sub-sections for truck bed transport between jobsites.

Boom Deflection Winch Cable Pull

Static load testing with 1,500 lbs at 40in forward boom extension results in 1.45in of boom tip deflection. The dual-speed hand winch requires 29 lbs of manual handle effort in low gear to lift maximum rated tonnage. Multi-strand galvanized steel cable winds across grooved pulleys without strand crushing. Automatic internal friction brakes lock the load in place upon handle release with zero downward drift over 4 hours.

Jobsite Clearances Winch Cable Care

Rolling the 345 lbs steel frame requires 26 lbs of push force across clean concrete slabs. Detent locking pins hold outriggers firm during heavy rigging operations. Do not buy this manual boom lifter for personnel elevation or operation on loose dirt grades.

• Inspect the main lift cable for broken wires or kinks every 10 operating hours.
• Coat the telescoping mast slide surfaces with dry film silicone lubricant every 40 hours.
• Pack the winch drive gear teeth with NLGI 2 grease every 90 days.
