ZOOMRY
Product Overview
ZOOMRY Tracked Truck Unloader series (ZRLD crawler models) combines a drive-over receiving hopper with self-propelled crawler mobility — purpose-built for soft ground mining sites, unpaved port yards, and temporary stockpile areas where wheeled units would bog down. Dump trucks drive onto the ramp and discharge directly into the hopper, feeding telescopic stackers or belt conveyors — eliminating wheel loader re-handling entirely.
Available in four configurations — ZRLS-TU1400, ZRLS-TU1800 (wheeled) and ZRLD-TU1400, ZRLD-TU1800 (tracked crawler) — the series handles 200–1,800 TPH across belt widths of 1,400–1,800 mm with 2 or 4 truck ramps. Unlike our wheeled truck unloader that requires a site tractor for relocation, ZRLD crawler models reposition independently in minutes. For smaller operations, see our 2-ramp compact truck unloader.
Why Choose Tracked Over Wheeled?
The critical advantage of ZRLD crawler models is independent mobility without towing equipment. On soft, muddy, or uneven ground — common in open-pit mines after rain, unpaved port yards, and temporary construction sites — wheeled units require a tractor or loader to reposition, adding downtime and equipment cost. ZRLD tracked truck unloaders crawl into position under their own power, deploy hydraulic jacks for stability, and begin receiving trucks in under 5 minutes.
| Feature | ZRLD Tracked (Crawler) | ZRLS Wheeled |
|---|---|---|
| Ground Condition | Soft, muddy, uneven — mining and unpaved yards | Firm, level — quarry floors, concrete pads |
| Mobility | Self-propelled — no towing required | Towable by site tractor |
| Repositioning Time | Under 5 minutes — self-deploy | 10–15 minutes — requires tractor |
| Best Application | Open-pit mines, port quaysides, temporary sites | Aggregate quarries, concrete plants, fixed yards |

Technical Components
Undercarriage: Wheeled vs Tracked
- Heavy-duty truck frame with maximum conveyor discharge height up to 6.3 m
- Super heavy duty tires (wheeled) or crawler tracks (tracked) optional
- Air brakes, directional lights, and mudflaps optional for on-site mobility
- Hydraulic jacks for stabilized operation during truck unloading
Low-Position Receiving Hopper
- Customized hopper width from 3.5 m to 5.7 m to match heavy trucks, wheel loaders, or excavators
- 5.0–7.5 kW electric/hydraulic power pack for hopper operation
- Optimized grid for aggregates and minerals to prevent oversize material entry
Heavy-Duty Conveyor Frame
- Belt width from 1,400 mm to 1,800 mm × length from 8 m to 20 m
- Heavy-duty frame specifically reinforced for heavy dump truck impact loads
- Belt speed from 1 m/s to 4 m/s with screw-type take-up for tension adjustment
Conveyor Belt Specifications
- EP conveyor belt — EP100 (5+4+2), EP200 (6+4+3) for impact resistance
- Site vulcanized splice for longer belt service life
- Ground-accessible start/stop push button controls; radio control optional
- Same belt series used on all ZOOMRY long distance belt conveyors
- Power supply: 380–460 V, 3 phase, 50/60 Hz — customizable to site conditions
Drive System and Pulley Configuration
- 200–1,800 TPH unloading capacity with dual 11 kW electric head-end drive (1,800 RPM, TEFC 3/60/460)
- Gear reducers from international brands like FLENDER / SEW
- Drive pulley – 20" (508 mm) diameter, ceramic lagged head pulley with Haerbin® bearings; backstops included
- Tail pulley with Haerbin® bearings for extended service intervals
Idlers and Options
- Long-life ZOOMRY Conveyor idlers — same design used across long distance conveyor projects; impact idlers in load area
- Optional: Belt Cleaner, discharge hood, wireless remote control, hydraulic undercarriage lift cylinder, hydraulic landing jack, on-board diesel GenSet
Key Advantages of Tracked Truck Unloader
- Self-propelled crawler mobility — repositions in under 5 minutes without a tractor or tow vehicle, even on soft ground
- Eliminates wheel loader double handling — trucks dump directly into the hopper; no loader needed
- Shorter truck cycle times — dump-and-go in under 3 minutes vs 8–10 minutes with loader re-handling
- Adapts to soft ground — crawler tracks distribute weight, preventing bog-down in muddy mining and port yards
- Reduces fuel costs and truck wear — trucks unload at a central point rather than traveling to remote stockpile areas
