When a contractor needs people or material to move up the side of a building, the choice of access equipment usually comes down to four machines: the suspended platform, the building hoist, the mast climbing platform and the building maintenance unit. Wuxi Powerston Technology Co., Ltd., based in Yixing, Wuxi, builds all four. This article walks through each product line, where it fits on a project, and why the way we fabricate the structure matters once the machine is on site.

 

A suspended platform — often called a gondola or hanging basket — is a motorised work platform suspended by wire ropes from a roof davit or outrigger frame. Workers stand inside the cage and ride up and down along the facade for painting, curtain-wall sealing, plastering, glass cleaning or light repair work. Our TSP-series systems support basket lengths up to 15 metres, which lets a single unit cover a wide horizontal band before it has to be re-positioned.
 

Typical jobs include high-rise exterior finishing, refurbishment of office towers, power-station cooling towers, bridge maintenance and shipyard hull work. Where a full scaffold would be too slow to erect and a mast climber too heavy for the facade, a suspended platform is usually the most cost-effective option.

 

The building hoist rides up a vertical mast lattice and carries either material only or both people and material. Our construction elevators reach lifting speeds of 96 m/min, which matters on a 200-metre tower when crews change at shift handover. The passenger version is fitted with full safety gear — overload protection, falling brake, lower and upper limit switches — while the material-only variant is tuned for payload and purchase cost.
 

The mast sections stacked in our yard are hot-dip galvanised after welding. The galvanising is not cosmetic: it protects the mast against rain and site dust over years of repeated erection and dismantling, and it is the reason these sections stay straight and bolt up cleanly on site.

 

A mast climbing platform (MCP) is a wide deck that climbs a fixed mast — or twin masts — to give masons, renderers and waterproofing crews a stable, full-width working surface. It is slower than a hoist but keeps the crew working continuously along the facade at one height, which is why it is the default choice for high-rise blockwork and external insulation work.

 

For permanent installation on high-rise buildings, we supply BMU systems, including telescopic-jib units mounted on the roof. A BMU stays with the building for its whole service life, so the roof trolley, jib, power supply and suspension rig are engineered to the building’s own geometry and wind loads rather than picked off a shelf.

 

For ground-to-top material movement on mid-rise sites, the material hoist and transport platform cover payloads from concrete buckets and formwork to finished goods. They are lighter in structure than a passenger hoist and faster to commission.

 

Our workshop runs laser cutters, laser pipe cutters, press brakes and drilling-milling machines under one roof. Main-structure tubes are cut to length and welded in jigs, then galvanised. Winch units, safety locks, control panels and electrical cabinets are assembled and tested before the cradle deck is fitted. Every unit goes through a no-load and load test before it leaves the factory, and we hold CE and EAC certification for the lines we ship to EU and EAEU markets.

 

Three questions narrow it down. How high is the building? What is the main job — finishing, maintenance or permanent cleaning? Does the local authority require a passenger-rated machine? Send us those answers along with the facade shape, and we will recommend the model, platform length and mast configuration rather than selling you the biggest unit in the catalogue.
