20-35 ft Towable Light Tower

The 20-35 ft towable light tower is the workhorse of temporary job-site lighting, typically deploying a 30 ft mast with metal halide or LED fixtures generating 104,000 to 172,000 lumens. This size class dominates highway work zones, utility staging yards, and night paving operations where a single unit illuminates 5,000 to 7,000 square meters. It represents the upper end of the two-band towable light tower ladder, beyond which portable applications give way to stationary or truck-mounted systems.

Spécifications clés

SpécificationPlage typiqueSignification
Mast height7–27 ft (telescoping to class maximum)Extended height determines coverage radius and ability to clear obstructions; most units deploy to 25–30 ft.
Total lumens104,000–172,000 lmCombined fixture output; higher values support larger work zones or tasks requiring higher lux levels.
Fuel tank capacity30–117 galDictates runtime between refueling; larger tanks support multi-shift or remote operations with infrequent site access.
Operating weight400–5,000 kg (880–11,000 lb)Includes chassis, mast, generator, and full fuel; determines tow-vehicle requirements and trailer-weight classification.
Power output2.6–17.5 kVAOnboard generator capacity; some units provide auxiliary power for tools or site equipment in addition to lighting loads.

Comment choisir

The 20-35 ft band suits applications requiring area lighting across several thousand square meters—road construction, large equipment staging, event setup, emergency response, and utility projects where a single tower replaces multiple smaller units. When coverage needs are confined to a single small work cell, driveway, or residential repair (under 2,000 m²), the Up to 20 ft Towable Light Tower offers easier handling and lower fuel consumption. This 20-35 ft class is the top rung of the towable ladder; operations requiring permanent installation, heights above 35 ft, or integration with fixed infrastructure typically move to stationary floodlight arrays or vehicle-mounted systems rather than a larger towable size.

Ce que cette taille peut gérer

  • Highway resurfacing and line-striping during nighttime lane closures
  • Utility substation construction and transformer installation in unlit yards
  • Commercial parking lot demolition and grading over multi-acre sites
  • Emergency response staging areas for wildfire, flood, or infrastructure failure
  • Bridge deck repair and inspection where scaffolding requires overhead illumination
  • Open-pit mining haul roads and loading zones operating around the clock

Sécurité et opération

  • Mast extension and retraction require clear overhead space and attention to power lines, tree canopies, and aircraft approach zones; many jurisdictions require overhead clearance surveys before deployment.
  • Stabilizing outriggers or ballast must be deployed on level ground to prevent tip-over during wind events; manufacturer load charts specify maximum wind speed for extended operation.
  • Refueling procedures require engine shutdown and ventilation; diesel spillage on hot engine components presents fire risk in dry or combustible environments.
  • Sound levels of 63–68 dB(A) at operator position necessitate hearing protection during maintenance and may trigger noise-ordinance compliance in residential or noise-sensitive zones.

Transport et logistique

  • Road-towable via pintle hitch or ball coupler by pickup trucks and service vehicles rated for 880–11,000 lb trailer loads; heavier models require ¾-ton or larger tow vehicles.
  • Self-contained axle and wheel assembly with DOT-compliant lighting and breakaway braking; most units meet highway speed limits without escort.
  • Compact footprint when stowed (mast retracted) allows storage in standard equipment yards and transport through residential streets to confined sites.

Alimentation

  • Integrated diesel generator (3–12 hp) powers lamps and onboard controls; no external electrical connection required for lighting operation.
  • Fuel consumption typically 0.6–1.8 gal/hr depending on load and ambient conditions; 30–117 gal tanks provide 17 to 195 hours of continuous runtime.
  • Some models include auxiliary 120/240 V outlets (up to 17.5 kVA) for powering hand tools, chargers, or small site equipment alongside the lighting array.

Questions fréquentes

What ground area does a 30 ft mast typically illuminate to 20 lux?
A unit producing 150,000 lumens at 30 ft mast height illuminates approximately 5,000–7,000 m² to 20 lux (construction-site standard) under clear conditions; actual coverage varies with fixture aiming, atmospheric conditions, and reflective surfaces.
Can one vehicle tow multiple 20-35 ft light towers in tandem?
Weight and hitch design generally limit single-vehicle towing to one unit; tandem towing requires dedicated transport trailers or flatbeds and may exceed local axle-weight or combination-vehicle-length regulations without special permits.
How does metal halide compare to LED in this size class?
Metal halide fixtures dominate legacy models and offer lower upfront cost; LED units consume 30–50% less fuel for equivalent lumens, generate less heat, tolerate vibration better, and eliminate warm-up/restrike delays, but carry higher acquisition cost reflected in newer inventory.
