In the realm of modern high-rise construction and maintenance, suspended platforms have emerged as indispensable tools for ensuring both efficiency and worker safety. These platforms, often seen hanging from the roofs of tall buildings, allow workers to perform various façade operations with flexibility and precision.
As cities expand vertically and architectural design becomes more complex, the demand for reliable and secure suspended access solutions has intensified. Among the many models available in the market, the ZLP 630 suspended work platform has distinguished itself as one of the most commonly used and trusted platforms for medium-to-high elevation projects.
This article provides an in-depth look at suspended platforms in general, with a particular focus on the ZLP 630 model, highlighting its structure, advantages, applications, and safe operation guidelines.
The ZLP 630 suspended work platform is part of the ZLP series, widely recognized for its robust performance and reliability. It is the most frequently adopted model across the construction, maintenance, and façade finishing industries.
Model Significance:
"ZLP" stands for "Zulian Lifting Platform" (a transliteration of Chinese origin), while "630" denotes the rated lifting capacity of 630 kg, making it ideal for carrying two workers and their tools.
The suspended platform, specifically the ZLP 630 suspended work platform, offers a reliable and efficient solution for high-rise construction and maintenance. With a rated load capacity of 630 kg, a lifting speed of 9–11 m/min, and customizable platform length up to 6 meters, it ensures safety and flexibility. Powered by 2 × 1.5 kW motors and compatible with 380V/50Hz or tailored voltages, its adjustable suspension mechanism adapts easily to various rooftop conditions.

The suspended platform, particularly the ZLP 630 suspended work platform, comes equipped with essential safety features such as standard safety locks and limit switches to ensure secure operation. Its hot-dip galvanized components provide excellent corrosion resistance, ideal for harsh environments. Additionally, optional features like overload sensors, anti-sway devices, and fall arrest systems enhance safety and performance for various project needs.
The ZLP 630 platform offers a perfect balance of strength, safety, and adaptability, which makes it an ideal choice for a wide range of high-altitude applications.
Moderate Load Capacity:
With a rated load capacity of up to 630 kg, the platform can comfortably accommodate two workers along with their tools and materials. This balance ensures efficient work without compromising safety or operational stability, making it ideal for medium-scale projects.
Quick Assembly & Portability:
Its modular design allows for rapid assembly and disassembly directly on site, significantly reducing setup time. This feature is especially valuable when working across multiple locations, enabling teams to move quickly and maintain productivity without the delays associated with traditional scaffolding systems.
Adjustable Platform Length:
The platform length is customizable up to 6 meters, allowing it to adapt to different building façades, including irregular or complex architectural designs. This flexibility improves access and coverage, reducing the need for repositioning during work.
Reliable Hoist System:
Equipped with a dual hoisting mechanism powered by two motors, the ZLP 630 ensures smooth and stable lifting and descent. This system minimizes jerking and slippage, providing workers with a secure and comfortable operating experience at height.
Comprehensive Safety Features:
Safety is prioritized through integrated fall arrest devices, limit switches, and emergency brake mechanisms. These components work together to protect operators and maintain a safe working environment, even in challenging conditions.
The ZLP 630 suspended platform is designed for versatility across different industries and work environments:
Building Façade Installation & Maintenance:
This platform is ideal for tasks such as curtain wall mounting, glass installation, and aluminum panel setup on high-rise buildings. Its customizable length and adjustable suspension mechanism allow workers to safely and efficiently perform exterior façade work, even on complex architectural designs.
Painting, Cleaning & Coating:
The ZLP 630 is widely used for exterior wall painting, waterproofing treatments, and window cleaning on skyscrapers and tall structures. Its stable and smooth lifting speed enables precise control, ensuring high-quality finishes and effective maintenance while minimizing risks for workers operating at great heights.
Window Glass Replacement:
Technicians benefit from the suspended platform’s ability to access specific floors or sections of a building. This makes it especially suitable for repairing or replacing broken or damaged glass units without the need for scaffolding or other cumbersome equipment.
Special Structures:
The ZLP 630 excels in servicing chimneys, silos, water tanks, and other cylindrical or irregular vertical surfaces. Its flexible suspension height adjustment and robust load capacity support safe operations on these challenging structures.
Infrastructure Projects:
In large-scale infrastructure maintenance, the suspended platform enables thorough inspection and upkeep of bridges, dams, and expansive archways. It allows workers to reach difficult areas safely and perform necessary repairs or cleaning efficiently.
To ensure optimal performance and longevity of the ZLP 630 platform, proper operation and maintenance practices must be followed.
Workers must undergo certified training
Familiarity with control systems and emergency protocols is essential
Use of PPE (Personal Protective Equipment) is mandatory
Check steel wire ropes for damage or wear
Inspect hoists and brakes for functionality
Test the electrical control system
Ensure that safety locks and limit switches are operational
Lubricate moving components regularly
Clean the platform after each use
Conduct periodic load testing
Check for rust or corrosion, especially in marine or high-humidity environments
Platform not rising: Check motor power supply and control box
Uneven lifting: Inspect if wire ropes are entangled or motors are desynchronized
Safety lock triggering: Indicates imbalance or excessive tilt—reset and relevel platform
Safety is the cornerstone of working with suspended platforms. The ZLP 630 is equipped with multiple features to ensure the operator's protection, but proper usage is key.
Do not operate in winds above 6 Beaufort scale (about 38–49 km/h)
Avoid using during thunderstorms or heavy rain
Anti-fall safety locks: Instantly lock the wire rope in case of rope breakage or platform tilt
Limit switches: Prevent the platform from going beyond its upper or lower limits
Emergency Stop Button: Instantly halts all movements in an emergency
Leakage Protection Device: Shuts off power in case of electrical faults
Inspect and test before every shift
Do not overload the platform
Ensure wire ropes are correctly fixed and tensioned
Maintain communication with ground personnel during operation
Operators must know how to activate manual descent
Rescue plans should be in place for sudden failures or accidents
Always have a fire extinguisher and first aid kit on site
The suspended platform is a cornerstone of safe and efficient high-rise construction and maintenance. Among various models, the ZLP 630 suspended work platform offers a reliable solution with proven performance in thousands of projects worldwide.
