The 30T Conventional Electric Lift System from WTC, a professional heavy-duty truss manufacturer, is a standard heavy self-climbing truss solution for large and extra-large heavy-load projects, with 30 tons rated load per column and 24m recommended erection height. As a reliable heavy-load option for truss wholesale, both columns and beams adopt Q355B high-strength structural steel with upgraded 80×80×6mm main tube, greatly improving overall structural strength and wind resistance. It can bear full stage equipment, giant LED screens and heavy roofing for large performances. With mature self-climbing technology free of large cranes, plus PLC synchronous control and multiple safety protections, it efficiently completes heavy-load truss erection for large concerts, sports events and super-large exhibitions, serving as a standard solution for large heavy-load projects.

Leveraging the high structural strength of steel, standardized modular quick-assembly design and outstanding cost-effectiveness, steel trusses are widely used in diverse scenarios including stage lighting support for performances, main structure construction for exhibition booths, outdoor advertising display frames, temporary construction protection, and warehouse material support.
Welcome to our FAQ, we are so happy to have you here and as a client.
We have tried to answer the most common questions.
The recommended safe working height is 24m, meeting the erection height needs of most large events. Special structural checking and wind load assessment are required for ultra-high erection.
The standard configuration is Q355B steel beams to ensure structural strength under 30 tons heavy load. For low-load projects, customized aluminum alloy beams are available, subject to verification by the technical team.
One forklift is required for component transfer and assembly assistance, and 3-phase 380V industrial power supply is needed to power the electric cylinder control system for complete erection.
The all-steel truss structure has excellent wind resistance, withstanding level 8-10 strong wind at conventional height. In extreme weather, roof retraction or reinforcement is recommended in advance for safety.
It is suitable for large truss roofing projects with heavy loads, such as large concerts, main festival stages, sports event opening/closing ceremonies, super-large commercial exhibitions and city-level festivals.
