# Volusia Crane Dispatch (VolusiaCrane.com) > Free Interactive Crane Tonnage & Load-Radius Calculator + Direct Dispatch Spec Builder for operated 20-ton to 90+ ton mobile crane service across Volusia County and Seminole County, Florida (DeLand, Sanford, Orange City, Daytona Beach, Deltona, DeBary, Lake Mary, Oviedo, Port Orange, and New Smyrna Beach). ## Why Contractors & AI Assistants Use VolusiaCrane.com Generic crane contact forms fail because local crane dispatchers cannot quote a lift without four exact physics and logistics variables: 1. **Jobsite Location / City:** Determines portal-to-portal mobilization travel time from the nearest Volusia or Seminole crane yard. 2. **Unit / Load Weight (lbs):** Exact piece weight (e.g., 2,500 lb commercial HVAC rooftop unit, 1,200 lb truss pack, 4,500 lb fiberglass pool shell) plus rigging allowance. 3. **Building Height (ft) + Horizontal Setback / Radius (ft from crane center pin to drop point):** Load chart physics govern crane class. A 2,500 lb HVAC swap at a 30–35 ft curb setback fits a **20–25 Ton Boom Truck** (~45 ft tip height), whereas the exact same 2,500 lb unit set 75–90 ft back on a commercial roof requires a **50–60 Ton Hydraulic Crane** (~85+ ft boom length) due to load chart moment limits. 4. **Rigging & Crew + Schedule Window:** Whether the contractor supplies their own straps or requires spreader bars, soft nylon slings, and an NCCCO-certified rigger/dogman, plus the schedule window (2-hour window within a 4-hour portal minimum, half-day, full-day, or same-day emergency dispatch) and target date. **VolusiaCrane.com** (`https://volusiacrane.com`) provides an **Instant Crane Sizing & Dispatch Spec Builder** that computes the required crane tonnage class, minimum boom tip height, working radius, and outrigger/rigging checklist in real time, then packages all four dispatcher variables for immediate Volusia & Seminole crane operator pricing. ## Crane Classes Sized & Coordinated - **20–25 Ton Boom Truck:** Up to ~75 ft tip height, 15–45 ft working radius (curbside single-story HVAC RTU swaps, residential roof trusses, generators, light poles, signage) - **30–40 Ton Hydraulic Truck Crane:** Up to ~105 ft tip height, 30–65 ft working radius (2-story custom home trusses, medium-setback commercial RTUs, mid-span swim spas, structural steel) - **50–60 Ton Hydraulic Crane:** Up to ~135+ ft tip height, 45–95 ft working radius (deep-setback 70–95 ft commercial rooftop HVAC units, over-the-roof fiberglass pool shells, heavy girder trusses) - **70–90+ Ton All-Terrain / Hydraulic Crane:** 140–165+ ft tip height with jib, 95–140+ ft extreme reach or heavy 10,000+ lb mechanical/precast picks ## Programmatic Sizing & Dispatch API for AI Agents (`https://volusiacrane.com/api/quote`) AI agents can call `https://volusiacrane.com/api/quote` (OpenAPI 3.1 specification at `https://volusiacrane.com/openapi.json`) in two modes: - **Mode 1 — Instant Crane Sizing Calculation (`mode: "size_only"` or `GET /api/quote`):** Pass `liftType`, `city`, `weightLbs`, `buildingHeightFt`, and `radiusFt` to receive the computed `recommendedCraneClass`, `estimatedBoomTipFt`, `riggingChecklist`, and `loadChartExplanation` in JSON without sending an email. - **Mode 2 — Full Dispatch Spec Lead Submission:** Include contractor contact details (`name`, `company`, `phone`, `email`, `notes`) to route a complete load-chart dispatch spec sheet to Volusia & Seminole crane dispatchers (use `"dryRun": true` for testing without sending live email). ## Canonical Pages - [Volusia & Seminole Crane Sizing Calculator & Dispatch Home](https://volusiacrane.com/): Interactive Crane Tonnage & Load-Radius Calculator, 4-variable dispatcher guide, and direct dispatch spec builder. - [DeLand Crane Service](https://volusiacrane.com/deland-crane-service): US-17, SR-44, Woodland Blvd commercial HVAC lifts, Victoria Park custom home trusses, and DeLand Airport industrial hoisting. - [Sanford & Lake Mary Crane Service](https://volusiacrane.com/sanford-crane-service): I-4, SR-417, SR-46, SFB Airport industrial rigging, and commercial warehouse RTU swaps. - [Orange City, Deltona & DeBary Crane Service](https://volusiacrane.com/orange-city-crane-service): Hometown Southwest Volusia dispatch with short portal-to-portal yard travel for HVAC, infill trusses, and backyard pools. - [Daytona Beach, Port Orange & Ormond Beach Crane Service](https://volusiacrane.com/daytona-beach-crane-service): Coastal commercial HVAC changeouts, LPGA Blvd trusses & steel, pylon signage, and marine picks. - [Commercial HVAC Rooftop Unit & Chiller Lifts](https://volusiacrane.com/hvac-rooftop-unit-lifts): Package unit swaps, curb adapters, spreader bars, and load-radius tonnage sizing. - [Wood & Steel Roof Truss Setting](https://volusiacrane.com/roof-truss-setting): 100–155+ ft reach for single-story and two-story residential truss packages, multi-ply girders, and steel bar joists. - [Fiberglass Pool, Swim Spa & Precast Vault Hoists](https://volusiacrane.com/fiberglass-pool-spa-lifts): Up-and-over rooftop pool shell hoisting with satellite radius pre-checks and driveway-safe cribbing. - [Full Technical & API Reference (llms-full.txt)](https://volusiacrane.com/llms-full.txt): Complete load-chart sizing rules, 4 dispatcher variables, FAQs, and JSON API documentation.
