Fixed Telescopic Belt Conveyor

Fixed Telescopic Belt Conveyor is designed for efficient loading and unloading of goods in warehouses, logistics centers, docks, and distribution facilities. As a professional China manufacturer and supplier, we provide stable and durable telescopic conveyor solutions that significantly reduce manual handling and improve operational efficiency.

Advantages

1.It enables the long-distance continuous conveying of bulk materials (such as sand and gravel, coal, grain, etc.), and features both the dual attributes of fixed conveying and flexible expansion.  

2.The effective conveying length of the fixed telescopic belt conveyor can be adjusted via a telescopic mechanism, adapting to the position change requirements of different discharge and feeding points.

3.It can be used in conjunction with loaders, stackers, crushers and other equipment to form a flexible material transfer system.

4.It supports forward and reverse conveying operations, meeting the diverse working conditions such as material loading, unloading and stacking.

Characteristics

1.Flexible and adjustable: The core telescopic mechanism can be controlled manually or electrically to quickly adjust the conveying length without repeated disassembly and assembly of equipment, adapting to changing working scenarios.

2.High space utilization: The overall length of the machine is shortened in the retracted state, reducing site occupation; it can cover a larger working range when extended.

3.Stable operation: Adopting a fixed installation method, the machine body has high rigidity, low vibration during operation and stable conveying efficiency.

4.Easy to operate: The telescopic control method is simple, and it can be equipped with a remote control function to reduce the intensity of manual operation.

5.High versatility: Different types of conveyor belts can be selected according to material characteristics, suitable for the conveying of various bulk materials.

Basic Requirements for Conveyor

Type of conveyed materials (bulk materials, piece goods, particle size, viscosity, corrosivity, abrasiveness, e.g., coal, sand and gravel, grain, chemical raw materials); rated conveying capacity (t/h); conveying distance (maximum and minimum telescopic stroke, m); conveying inclination (braking configuration shall be confirmed emphatically for horizontal, upward, downward conveying).

Notes for In-use Operation

1. Telescopic Operation Specifications: Before telescopic operation, ensure there is no residual material on the conveyor belt and no personnel or obstacles nearby. Telescopic operation with material on the conveyor belt or starting the conveyor during telescopic operation is strictly prohibited.

2. Mechanism Maintenance: Regularly check the wear of the telescopic guide rails, chains, gears, and other transmission components. Add lubricating oil as needed to prevent jamming, abnormal noises, and other malfunctions.

3. Limit Protection: Ensure the telescopic stroke limit switches are sensitive and effective to avoid over-extension or retraction that could damage the mechanical structure.

4. Conveyor Belt Protection: During telescopic operation, carefully observe the conveyor belt tension to prevent slippage or deviation due to length changes. Do not convey sharp or pointed materials to avoid scratching the conveyor belt.

5. Safety Protection: Protective railings and warning signs must be installed on both sides of the telescopic section to prevent personnel from approaching moving parts. Disconnect the power supply after stopping the machine to prevent accidents caused by misoperation.

Product Parameters

When selecting and purchasing conveying equipment, the following issues need to be paid attention to:

1.What are the maximum conveying distance and lifting angle of the conveyor? Does it support multi-section splicing?

The conveying distance of the conveyor is determined by the straight-line distance from the feeding position to the discharging position, in meters. It supports modular splicing with an elevation angle ranging from 0° to 90°.

2.What is the operating energy consumption of the equipment? What is the motor power?

The operating energy consumption of the equipment refers to the material conveying condition, and the motor power is calculated based on the material conveying capacity and speed.

3.What is the service life of wearing parts (conveyor belt, idlers, rollers)? What are the procurement price and supply cycle of accessories?

Generally, vulnerable parts need regular inspection and replacement according to usage conditions, and the production cycle is determined based on the provided dimensions and other requirements of the spare parts.

4.Does the equipment have safety devices such as overload protection, belt breakage warning and anti-deviation?

Three Core Devices + Supporting Safety Devices: Forming a Full-Link Protection System

In industrial practical applications, the overload protection, belt breakage protection and deviation prevention devices must be interlocked with supporting devices such as rope pull emergency stop switches, slip detection switches and material flow detection switches to realize the whole-process control of monitoring - early warning - alarm - shutdown - protection. The specifications of the core supporting devices are as follows:

1.Rope Pull Emergency Stop Switch: Installed along both sides of the conveyor frame in the entire length; the machine shuts down immediately once the pull rope is triggered. It is applicable to on-site emergencies (e.g., personnel straying into the working area, massive material spillage) and mandatory for all working conditions.

2.Slip Detection Switch: Mounted at the contact position between the roller and the conveyor belt to monitor belt slippage (e.g., the roller rotates while the belt does not). An alarm/shutdown will be activated when the slippage exceeds the threshold, preventing belt abrasion, burning and material accumulation.

3.Material Flow Detection Switch: Installed at the guide chute to monitor the material conveying capacity and prevent material blockage (a precursor to overload), and it is interlocked with the overload protection device.

5.Requirements for the telescopic system?

Telescopic drive method (electric/hydraulic), telescopic speed (m/min), material of the telescopic frame (steel section specifications, such as channel steel/square tube, load-bearing capacity), track and roller configuration (wear resistance, preventing jamming).

6.Can the equipment be integrated with a PLC control system to realize functions such as automatic start-stop, speed regulation and material linkage?

The belt conveyor integrated with a PLC control system enables full automation functions including automatic start/stop, frequency conversion speed regulation, upstream & downstream material linkage, safety device interlocking and operation monitoring. With PLC as the core control unit, it links with frequency conversion drives, sensors, actuators and upstream & downstream equipment to replace manual operation, adapting to both independent control of a single conveyor and multi-machine linkage of the entire production line. It also complies with the protection requirements of special working conditions such as high-temperature coke, corrosive chemical raw materials, ores and grains.
