Electric Suspended Work Platform
The Electric Suspended Work Platform is a temporary, motorized access system engineered for vertical transportation of personnel, tools, and materials during exterior building construction and maintenance. Driven by specialized traction hoists along steel wire ropes, it serves as a flexible, cost-effective alternative to traditional frame scaffolding for high-rise facades.
Built with modular aluminum or hot-dip galvanized steel components, the platform length is adjustable from 2m to 7.5m to fit complex building geometries. Key structural assemblies comply with EN 1808 standards, ensuring reliable performance under harsh outdoor job-site conditions.

Key Features
Dual-Traction Hoist System: Employs alpha-numerical gearboxes machined from 38CrMoAl alloy steel, heat-treated to HRC 55-60 for wear resistance and consistent torque transmission.
Progressive Anti-Tilt Safety Locks: Automatically clamp onto the secondary safety rope within 100mm if the platform tilts beyond 3 degrees or if the primary suspension rope fails.
Electrical Control Panel: Integrated with phase-failure protection, leakage circuit breakers, emergency stop buttons, and upper-limit travel switches conforming to IP55 protection ratings.
Modular Platform Assembly: Sections connect via high-tensile 8.8-grade bolts, allowing fast on-site reconfiguration into 2m, 2.5m, 3m, or customized combined lengths.
Applications
Facade Construction: Exterior bricklaying, concrete repair, and external insulation installation on commercial and residential towers.
Glass & Cladding Installation: Curtain wall assembly and structural glazing where precise vertical positioning is required.
Surface Finishing: Spray painting, sandblasting, waterproofing, and exterior wall cleaning.
Infrastructure Maintenance: Bridge pier inspections, chimney repairs, and dam maintenance operations.
Configuration & Customization
Platform Material Options: Choose between lightweight aluminum alloy (corrosion-resistant, easier manual handling) and hot-dip galvanized steel (high impact resistance, lower initial investment).
Suspension Jib Variations: Parapet clamps, flat roof counterweight frames, and L-shaped parapet extensions available for complex roof structures.
Voltage Adaptation: Custom transformer configurations to match regional industrial grids (e.g., 220V 3-phase or 480V 3-phase).
OEM/ODM Support: Custom platform branding, color-coding, and specialized dimensions for specific architectural geometries.
Manufacturing & Quality Control
Production Infrastructure: Fabricated in-house using Trumpf CNC laser cutting machines, OTC robotic MIG welding cells, and Mazak CNC horizontal boring mills to maintain structural dimensional tolerance within +/- 0.5 mm.
Surface Treatment Facility: All structural steel elements undergo automated acid pickling, zinc phosphating, and hot-dip galvanizing in an enclosed zinc bath (minimum coating thickness: 80 um), followed by electrostatic powder coating.
Factory Testing Protocol:
- 100% static load testing at 1.25 times the rated capacity on dedicated test rigs prior to dispatch.
- Dynamic load endurance testing at 1.1 times capacity for operational verification.
- Electrical insulation resistance and dielectric strength testing on every control box.
Quality Assurance & Certifications: Manufactured under strict ISO 9001 certified quality management systems; hoists and safety locks carry independent CE and TUV type-approval certifications.
Packaging & Delivery
Export Packaging: Hoists and electrical control boxes packed in fumigation-free plywood crates; platform sections bundled with heavy-duty steel strapping and rubber edge protectors to prevent transit friction.
Logistics & Loading: Optimized for 20ft or 40ft standard maritime containers. A standard 20ft container accommodates approximately 5 to 6 complete sets of ZLP630 platforms including counterweights.
Lead Time: Standard configurations ship within 10 to 15 business days; custom orders require 20 to 25 business days.

Q: What is the maximum working height of the platform?
A: The standard configuration supports heights up to 100 meters using standard wire rope lengths. Extended configurations up to 300 meters are available upon request with heavier hoist drum capacities.
Q: How does the safety lock function during a wire rope break?
A: The centrifugal safety lock constantly monitors rope speed. If a rope breaks or slips, causing the platform to descend abnormally, the lock automatically grips the safety wire rope and locks the platform within a displacement of less than 100mm.
Q: What power supply is required on the job site?
A: A standard 3-phase industrial power supply (380V/415V, 50Hz/60Hz) is required. A portable diesel generator of at least 5kW is recommended if grid power is unavailable on site.
Q: What routine maintenance is required?
A: Inspect wire ropes daily for broken wires or wear. Lubricate the hoist gearbox internal gears every 3 months with high-temperature lithium grease, and test the emergency descent brake weekly.
