100 kVA Generator Rental for Tower Crane
High-surge, VFD-compatible 100 kVA prime diesel generators engineered for uninterrupted hoisting, slewing, and heavy lifting operations across UAE construction sites.

100 kVA / 80 kWContinuous 400V / 50 Hz 3-Phase rating
Tested with VFD crane systems from Potain, Liebherr, and Zoomlion.
Engineered Power for Critical Crane Lifting
In Dubai's fast-paced high-rise and infrastructure construction sector, a tower crane is the central heartbeat of the job site. When a tower crane stops, structural concrete pours halt, steel reinforcement lifting ceases, and hundreds of workers are left idling. Ensuring an uninterrupted, stable electricity supply to the crane's hoisting, slewing, and trolley motors is paramount to meeting strict project completion deadlines.
Before permanent DEWA or utility grid power is connected to a site—or where grid connections experience voltage sags and capacity constraints—a dedicated 100 kVA commercial diesel generator is the industry standard power solution. It provides the exact balance of active electrical output (80 kW), high motor-starting surge capacity, and responsive governor control needed to handle the dynamic shock loads of heavy lifting.
Energex Equipment Rental delivers turnkey 100 kVA generator packages specifically configured for modern tower cranes equipped with Variable Frequency Drives (VFDs) and electronic control systems across Dubai, Abu Dhabi, Sharjah, and all seven Emirates.

Why Choose Energex for Tower Crane Power?
Minimizing crane downtime with high-surge alternators, precision voltage regulation, and round-the-clock maintenance.
High Motor-Starting Surge Capacity
Tower crane hoist motors draw massive inrush current when lifting maximum payloads. Our 100 kVA generators feature heavy-duty alternators with Class H insulation and PMG excitation to absorb sudden motor surges without tripping.
Digital AVR Safe for Crane VFD Inverters
Modern cranes use sensitive variable frequency drives (VFDs) that trip if voltage or frequency fluctuates. Our digital automatic voltage regulators maintain steady output within ±1.0%, preventing inverter fault shutdowns.
24/7 Dedicated Site Support & Emergency Dispatch
Because tower crane downtime stops the entire site, our mobile service engineers are on standby 24/7 across the UAE with fully equipped service vehicles, spare parts, and standby backup generators.
Extended Fuel Autonomy & Scheduled Refueling
Equipped with high-capacity integrated base fuel tanks and three-way fuel valves for external bulk tank connection, ensuring non-stop operation through multiple 12-hour construction shifts.
Super Silent Soundproof Enclosure
Acoustic canopies limit operating noise to 68–72 dBA at 7 meters, fully complying with Dubai Municipality and Abu Dhabi environmental noise regulations for urban, residential, and night-shift construction.
Turnkey Setup & Heavy-Duty Cabling
We supply heavy-duty armored copper cabling, crane distribution panels, earthing rods, and Automatic Transfer Switches (ATS) with expert on-site connection and commissioning.
Lifting Equipment & Crane Compatibility
Tested and proven across major tower crane brands and construction hoisting systems in Dubai and the UAE.
Top-Slewing Tower Cranes
Ideal for medium-to-large top-slewing cranes from leading manufacturers including Potain, Liebherr, Zoomlion, Terex, and Comansa with hoist motors up to 45 kW.
Flat-Top & Urban Luffing-Jib Cranes
Powers compact urban cranes operating on tight high-rise developments in Downtown Dubai, Business Bay, and Dubai Marina with strict acoustic and emissions limits.
Construction Hoists & Passenger Lifts
Provides dedicated or dual-purpose power for Alimak and GJJ rack-and-pinion construction hoists moving personnel and building materials up multi-story facades.
Precast & Heavy Steel Erection
Handles the severe repetitive lifting loads required during heavy precast concrete element placement and structural steel frame erection.
Auxiliary Concrete Bucket & Skip Pouring
Supports continuous crane operations for concrete bucket transfers and skip lifting during foundation and slab pouring shifts.
Dual-Genset Redundancy for Critical Lifts
Available in synchronized or automatic changeover pairs (ATS) for critical infrastructure lifts where power failure mid-air is not an option.
Engineered Specifications for Crane Lifting
Optimized for heavy motor starting currents, VFD drives, and high-ambient UAE summer conditions.
