Plug–in Ladder Hoist

The 3S INDUSTRY Ladder Hoist is a customized portable solution for lifting various materials in limited space. It can stably and efficiently lift heavy materials to a designated height. Application Scenarios: Low-rise building construction and maintenance Roof photovoltaic installation Logistics cargo lifting (furniture/household appliances) Features Tool-free assembly Small-sized & lightweight design Safety specialized catch Multiple transport platforms Equipped with fall protection system Advantages Modular components connect via quick-release mechanisms without wrenches Drive unit weighs only 65kg; system fits in a standard minivan Mechanical redundancy engages instantly in the event of rope failure Interchangeable carriers for different materials (panels, tiles, buckets) Benefits Rapid Deployment: Reduces site setup time by up to 60% Logistical Efficiency: Eliminates the requirement for heavy haulage Risk Mitigation: Ensures compliance with strict safety regulations (CE/UL) Operational Versatility: One unit serves multiple trades Product Details Rail Section Connectors Connects the guide rail sections by using the designed bolts and eye nuts without tools, while meeting the required torque. Drive Unit Allows for manual load lowering and easy transportation. The frequency converter control (available only in the MH03L250-expert model) provides a smoother start and stop. Roof Support Bracket Provides support to the guide rails on the roof to ensure stability and protect the roof from damage. Knee Section Allows the rail to fit properly to the roof or other inclined surfaces by adjusting its angles between 20° and 42°. Carriage It is welded with carbon steel and offers a safety catch mechanism in case the wire rope breaks. LBS Grooved Drum Installed in the drive unit, it guarantees the orderly and stress-free winding of multi-layered wire ropes, reducing friction and extrusion deformation and extending service life.
