Differences Between ISUZU 28m & 31m Telescopic Aerial Platform Truck
1. Core Working Height & Horizontal Reach (Key Distinction)
ISUZU 28m Aerial Truck
- Max working height: 28 meters (platform floor height 26m + guardrail 2m)
- Max horizontal outreach: 14.5–16m
- Working radius at full height: 4.5–5m
- Boom structure: 5-section hexagonal synchronous telescopic arm, standard fly jib
ISUZU 31m Aerial Truck
- Max working height: 31 meters (platform floor height 29m + guardrail 2m)
- Max horizontal outreach: 15.5–17m (1m wider horizontal coverage)
- Working radius at full height: 5–5.5m
- Boom structure: 6-section high-strength decagon telescopic arm, reinforced fly jib for high-altitude offset operation
2. Chassis & Body Dimension Differences
28m Model
- Wheelbase: 3360mm / 3815mm (ISUZU KV100 standard)
- Overall dimension: ~6000 × 2000 × 2700 mm
- GVW: 4495kg (light blue-plate, easy urban entry)
- Tire: 6.50R15 steel wire tire; oil brake optional
31m Model
- Wheelbase: 3815mm long wheelbase (mandatory for longer boom stability)
- Overall dimension: ~6550 × 2050 × 2780 mm (longer & wider body)
- GVW: 4495kg (still blue-plate but heavier curb weight)
- Tire: 7.00R16 heavy-duty steel wire tire; air brake as standard for safety
3. Outrigger & Stability System
28m Aerial Truck
- Double front-rear hydraulic outriggers, horizontal span 5.8m, longitudinal span 6.0m
- Standard soft leg protection alarm, basic hydraulic balance control
- Suitable for narrow urban roads, compact parking spaces
31m Aerial Truck
- Reinforced heavy-duty square outriggers, wider cross span (6.0m horizontal / 6.2m longitudinal)
- Dual hydraulic balance cylinders + real-time tilt monitoring via LCD screen
- Larger support footprint, higher anti-tipping safety factor for high-altitude heavy load

4. Hydraulic & Operation Configuration
28m Version
- Single main hydraulic cylinder, standard manual + wired remote control
- Simple mechanical operation panel, basic height/radius display
- Standard 1.6m stainless steel working basket, rated load 200kg (2 workers)
31m Version
- Double external telescopic hydraulic cylinders, synchronous boom extension
- Full set of control modes: cab manual + turntable handle + wireless remote with LCD

5. Weight, Fuel Consumption & Transit Flexibility
ISUZU 28m
- Lighter curb weight, lower fuel consumption during transit
- Shorter overall length, excellent maneuverability for downtown, street lamp maintenance, residential building exterior repair
- Low road restriction, convenient short-distance frequent relocation
ISUZU 31m
- Heavier upper body, slightly higher diesel consumption
- Longer vehicle length, needs wider turning space; less ideal for ultra-narrow alleyways
- Higher transit cost for long-distance transportation
6. Application Scenarios Matching
Choose 28m If Your Work Covers:
- Street light, traffic signal, medium-height billboard maintenance
- 6–8 storey residential building exterior cleaning & renovation
- Factory low-rise workshop pipeline, air conditioner installation
- Urban narrow old town regular aerial maintenance
Choose 31m If Your Work Covers:
- 9–10 storey commercial buildings, high-rise mall exterior construction
- Large stadium, bridge, wind power auxiliary maintenance
- High-rise municipal lighting, overhead line inspection
- Projects requiring extra horizontal outreach over obstacles (trees, building eaves)
7. Price & Cost Gap
ISUZU 28m aerial platform truck: Lower manufacturing & purchase cost, cheaper maintenance and spare parts
ISUZU 31m aerial platform truck: Higher raw material cost (longer high-strength steel boom, upgraded hydraulic system, wide chassis), selling price +8%~15% compared with 28m model
