Key Facts About MAX8.21 3t Wall Traveling Jib Crane
The six most valuable FAQs for buyers — covering what this crane is, how to read its model number, its key lifting specifications, duty class, power & control options, and why it is ideal for longitudinal workstation handling.
1. What is this wall traveling jib crane and what is it designed for?
This is a MAX8.21 3 Ton Wall Traveling Jib Crane with a 3-ton lifting capacity, designed for longitudinal workstation handling along building walls in machinery manufacturing, transformer assembly, and heavy equipment fabrication facilities. It runs on multi-tier wall tracks along structural building columns and operates independently below overhead bridge cranes.
Ideal applications: machinery manufacturing plants, transformer assembly halls, CNC machining bays, steel structure fabrication, and facilities with overhead EOT cranes requiring dedicated workstation lifting.
Alternative names for this crane: wall mounted traveling crane, longitudinal wall crane, multi-tier wall jib crane, workstation wall traveling crane.
2. What does "MAX8.21" mean in the model number?
- MAX = Yuantai wall traveling crane series designation
- 8.2 = Approximate cantilever reach in meters (8.2m class)
- 1 = Design variant number
The effective cantilever reach is 8.0 meters (8000 mm) from the wall track center to the hoist hook. The total jib beam length is 9.5 meters (9500 mm). The crane travels longitudinally along wall-mounted runways with a 2.9m vertical track gauge and 4.3m end carriage length.
Lifting height: 7.0 meters. Duty class: ISO A5. Power: 575V / 60Hz / 3P.
3. What are the key lifting specifications?
| Lifting Capacity | 3.0 t |
| Effective Cantilever Reach | 8.0 m |
| Total Jib Beam Length | 9.5 m |
| Lifting Height | 7.0 m |
| Vertical Track Gauge | 2.9 m |
| End Carriage Length | 4.3 m |
| Hoisting Speed | 0.8 ~ 5.0 m/min (Dual Speed / VFD) |
| Trolley Traversing Speed | 2.0 ~ 20 m/min (VFD) |
| Long Traveling Speed | 2.0 ~ 20 m/min (VFD) |
| Duty Class | ISO A5 |
| Power Supply | 575V / 60Hz / 3P |
| Total Weight | 5.0 t (approx.) |
| Quantity | 1 unit |
Buyer Tip: If your cantilever reach or lifting height requirements differ, Yuantai can customize the jib beam length and lifting height to suit your specific building column layout.
4. What is the duty class A5 and what does it mean for my application?
The duty class is ISO A5 (FEM/ISO classification), which means:
- Heavy duty cycle — suitable for regular daily use
- Rated for up to 2,000–4,000 hours of operation per year
- Ideal for machinery manufacturing, transformer assembly, and heavy equipment fabrication
- Perfectly matched to the demanding nature of continuous industrial workstation handling
What does this mean for you? If your facility operates multiple shifts per day with regular lifting, A5 is the right duty class. For occasional use, consider A3 or A4 duty cranes.
Duty class comparison: A3 = light duty (occasional use), A4 = medium duty (regular intermittent), A5 = heavy duty (regular daily), A6 = extra heavy duty (continuous).
5. What power supply and control options does this crane require?
Power Supply:
- Crane: 575V / 60Hz / 3-Phase
- Lifting Motor: 3.2 kW
- Trolley Travel Motor: 0.4 kW
- Long Travel Motor: 1.1 kW
- Control Voltage: 24V / 36V Low Safety Voltage
Control Modes:
- Pendant control — wired handheld controller with safety voltage
- Wireless remote control — for flexible positioning along the runway
Buyer Note: Pre-configured for 575V/60Hz 3-phase power (North American industrial standard). If your facility uses a different voltage (e.g., 380V, 415V, 440V, or 50Hz), please inform us during inquiry for customization.
VFD Advantage: Variable frequency drives on trolley and long travel provide stepless speed regulation and eliminate load swing across the 8m cantilever arm.
6. Why is this crane suitable for longitudinal workstation handling?
- 3t capacity — handles heavy machinery components
- 8.0m effective cantilever reach — deep load coverage into building aisles
- Longitudinal travel — serves all workstations along the bay wall continuously
- Operates independently below overhead EOT cranes — no interference with primary factory lifting
- VFD stepless speed regulation — eliminates load swing across the 8m cantilever
- ISO A5 heavy-duty rating — matches the demanding nature of continuous industrial work
- High overturning moment resistance — 4.3m end carriage and 2.9m wheel spacing distribute moment forces safely
- Unobstructed floor space — wall-mounted runways keep aisles clear
- 575V 60Hz compatibility — factory-built for North American industrial grids
Why buyers choose this model: It offers the perfect balance of lifting capacity, extended cantilever reach, and continuous longitudinal travel for large workshops where dedicated workstation lifting along building walls is required without interfering with overhead bridge cranes.
