Long-Reach Telescopic Conveyor for Deep Truck Loading
Three Section Telescopic Belt Conveyor
The YJ-INTL 3-Section Telescopic Belt Conveyor is engineered for loading and unloading operations where the conveying point needs to reach deep inside trucks, trailers or other vehicle compartments.
Compared with shorter telescopic configurations, the three-section structure provides a longer available extension range while keeping the machine retracted when the loading position does not require maximum reach. According to the supplied specification, the available configurations cover 4,000–7,000 mm fixed sections and maximum extension lengths from 5,000 to 9,500 mm.

Built for Deep-Reach Vehicle Loading
In a conventional loading operation, the distance between the warehouse dock and the cargo position inside a vehicle can become a bottleneck.
When cartons or parcels need to be moved deeper into the vehicle, operators may otherwise have to repeatedly carry or reposition goods manually.
The YJ-INTL three-section telescopic conveyor addresses this layout challenge by extending the conveying surface toward the vehicle interior.
The three-section arrangement is particularly relevant when the project requires:
- A longer operating reach
- Deep truck loading
- Extended unloading positions
- Limited manual carrying distance
- Frequent vehicle loading operations
- Integration with an existing warehouse conveyor line
The objective is not simply to make the conveyor longer, but to move the material-transfer point closer to the actual cargo position.
Three-Section vs. Shorter Telescopic Configuration
The primary difference is the available reach and structural configuration.
A three-section telescopic conveyor is more appropriate when:
- The loading point is relatively deep
- Longer extension is required
- The dock layout provides sufficient installation space
- The customer needs greater reach flexibility
- The vehicle loading process involves different cargo positions
The three-section configuration shown in the supplied specification supports maximum extension lengths up to 9,500 mm, giving it a substantially longer reach than a compact telescopic arrangement.
The final choice should still be based on the actual loading geometry rather than assuming that a longer conveyor is always the better option.
Hydraulic Height Adjustment
The technical sheet specifies a hydraulic configuration with:
- Hydraulic angle: 3.5°
- Mounting hole spacing: 615 mm
- Hydraulic stroke: 285 mm
A hydraulic lifting arrangement can be used where the conveyor needs to accommodate different vehicle-floor or loading-platform elevations.
This is particularly useful for loading docks where the relative height between the warehouse floor, conveyor and vehicle changes between operating conditions.
The exact lifting configuration should be determined from the customer's dock geometry
Where a 3-Section Telescopic Conveyor Fits
Truck Loading
The long extension range allows the conveyor to reach farther into the truck, making it suitable for outbound loading operations.
Truck Unloading
During unloading, goods can be transferred from deeper positions in the vehicle toward the warehouse side without requiring the conveyor to remain fixed at the dock entrance.
E-Commerce Fulfillment
The conveyor can be installed at outbound loading areas where packed orders need to move from the fulfillment operation into delivery vehicles.
Express & Parcel Hubs
Parcel distribution facilities can use telescopic conveyors as the final connection between sorting/consolidation operations and vehicle loading.
3PL Warehouses
The flexible extension range can be useful for logistics facilities handling different customers, vehicle types and loading requirements.
Manufacturing Dispatch
The system can transport finished cartons or packaged products toward trucks during dispatch operations.

FAQ
A three-section telescopic belt conveyor uses multiple nested conveyor sections that extend and retract to move the conveying point closer to the required loading or unloading position. It is mainly used where a longer reach is required between the fixed warehouse conveyor position and the vehicle.
According to the supplied specification, the maximum extension length reaches 9,500 mm in the 7,000 mm fixed-section configuration.
The listed fixed-section options are 4,000, 5,000, 6,000 and 7,000 mm, with different maximum extension lengths available for each configuration.
The main difference is the available reach and section arrangement. A three-section configuration is intended for applications requiring a longer extension distance, while the appropriate configuration should ultimately be selected according to dock geometry and required vehicle reach.
The specified conveying speed is 10–40 m/min and can be adjusted through variable-frequency control.
The specified extension and retraction speed is 10 m/min with variable-frequency drive control.
The rated load capacity shown in the supplied specification is ≤60 kg/m². The final allowable load should be confirmed against the actual product characteristics and equipment configuration.
The conveyor uses a 3 mm PVK impact-resistant composite belt with a steel-clamped belt joint according to the supplied technical specification.
The conveyor drive uses a 1.5 kW motor, while the telescopic movement uses a 0.4 kW motor.
