ZOOMRY
Product Overview
ZOOMRY Truck Unloader – Two Ramp Drive-Over Hopper is a compact truck receiving system purpose-built for small to medium quarries, sand & gravel yards, and construction material hubs. Dump trucks drive onto the dual ramps, discharge directly into the hopper, and depart — eliminating wheel loader re-handling entirely. With 200–3,000 TPH capacity and belt widths from 650 to 1,800 mm, it feeds telescopic stackers or belt conveyors for direct stockpiling or crusher feeding.
Compared to our 4-ramp wheeled truck unloader for high-volume sites, the 2-ramp configuration prioritizes compact footprint and lower upfront investment — handling up to 30 trucks per hour on a single approach lane. Available in wheeled and crawler chassis for aggregate quarries, mining, and port receiving points.
How a Two Ramp Truck Unloader Works
A dump truck reverses onto one of the two ramps and tips its load directly into the receiving hopper. The hopper's reinforced grid filters oversize material while the impact bed absorbs the discharge shock. A belt feeder meters material onto the inclined conveyor, which transfers it to a downstream mobile stacker, crusher feed system, or stockpile. The entire cycle takes under 3 minutes per truck — compared to 8–10 minutes when a wheel loader re-handles the same material. The dual ramp design allows one truck to position while another unloads, maximizing throughput without the space requirement of a 4-ramp system.
Is a 2-Ramp Truck Unloader Right for Your Site?
The 2-ramp configuration is the right choice when:
- Your site handles up to 30 trucks per hour — beyond this, a 4-ramp wheeled truck unloader reduces queuing
- Available space for truck approach lanes is limited — single lane access is sufficient
- Budget is a primary concern — lower upfront investment than 4-ramp equivalents
- Your operation is seasonal or project-based — quick deployment and lower capital commitment

Key Advantages of a Two Ramp Truck Unloader
- Eliminates wheel loader double handling — trucks dump directly into the hopper; no loader needed for re-handling to stockpile or conveyor
- Shorter truck cycle times — dump-and-go in under 3 minutes vs 8–10 minutes with loader re-handling
- Lower upfront investment than 4-ramp systems — ideal for sites with moderate throughput requirements
- Compact footprint — fits sites where space for wide approach lanes is unavailable
- Reduces fuel costs and truck wear — trucks no longer travel to distant stockpile areas
