ZR120D Grasshopper Conveyor

The ZR120D Grasshopper Conveyor is a heavy-duty core equipment developed by ZOOMRY specifically for high-load operations involving heavy bulk materials. As a primary 550 TPH (Tonnes Per Hour) conveyor and heavy bulk material conveying equipment, it is equipped with a super-large 15 m³ capacity hopper and achieves efficient continuous conveying at a belt speed of 2.5 m/s. It features a 20 mm-thick tear-resistant reinforced belt that can withstand long-term impact and wear from heavy bulk materials, while the dual hydraulic motor drive design provides sufficient power redundancy. Combined with a fault self-diagnosis system to reduce downtime, and having obtained international certifications including CE and EAC, it has become the preferred heavy-duty grasshopper conveyor with "high load-bearing capacity, high reliability, and low failure rate" for heavy bulk material scenarios such as heavy mining and deep-water ports.

Core Functions of the ZR120D Grasshopper Conveyor

As a professional heavy-duty grasshopper conveyor, the core competitiveness of the ZR120D Grasshopper Conveyor lies in "heavy-load bearing + power redundancy guarantee + intelligent fault management and control". Addressing the pain points of heavy bulk materials—"large weight, strong impact, and high requirement for operational continuity"—it solves the problems of traditional grasshopper conveyors (such as "prone to belt tearing, insufficient power, and difficult fault diagnosis") through targeted function optimization, while meeting the dual demands of "equipment durability and operational efficiency" in heavy-load scenarios.

Reinforced Tear-Resistant Belt

The equipment's belt adopts a custom reinforced structure with a thickness of 20 mm—twice that of ordinary grasshopper conveyor belts. The core layer is made of high-strength polyester canvas (EP300), and the upper and lower cover rubbers are wear-resistant natural rubber (hardness: 60 Shore A). Three layers of steel mesh are transversely embedded to enhance tear resistance, resulting in a tear strength of 800 N/mm, which is 120% higher than that of ordinary belts. The belt surface is processed with diamond-shaped anti-slip patterns with a depth of 10 mm, improving the anti-slip effect by 60% for heavy bulk materials (such as large ore blocks and heavy aggregates) and preventing materials from slipping or shifting during conveying. Meanwhile, both sides of the belt are equipped with 400 mm-high wear-resistant rubber skirts with built-in steel wire skeletons, which can resist deformation caused by lateral pressure from heavy bulk materials and reduce material side leakage, adapting to the conveying needs of heavy bulk materials with "high impact and strong wear".

Dual Hydraulic Motor Drive

The drive system adopts a dual hydraulic motor linkage design, with each motor having an output power of 18 kW and a total output torque of 4500 N·m—80% higher power reserve than single-motor drives. The dual motors drive the belt drum synchronously through a planetary reducer; even if one motor fails temporarily, the other can automatically switch to the "emergency power mode", maintaining 70% of the conveying capacity (approximately 385 TPH) and avoiding full-line shutdown due to power interruption. The hydraulic system is equipped with a dual-circuit independent oil supply design, with one-way valves between the circuits to prevent the impact of oil leakage in one circuit on the overall power output. At the same time, the hydraulic oil cooling system uses forced air cooling to control the oil temperature within 40-55℃, avoiding overheating and deterioration of hydraulic oil under heavy-load operations and extending the service life of motors and hydraulic components.

Intelligent Fault Self-Diagnosis System

The equipment is equipped with a self-developed intelligent fault self-diagnosis system, which collects real-time equipment operation data through more than 20 sensors distributed in the belt, drive, and hydraulic systems (such as belt tension sensors, motor temperature sensors, and hydraulic pressure sensors). The system can automatically identify 12 types of common faults, including abnormal belt tension, hydraulic motor overheating, oil circuit leakage, and hopper blockage. When a fault is detected, the HMI touchscreen will display a fault code and troubleshooting guidelines, and an audio-visual alarm will remind the operator. The fault identification accuracy rate is over 95%. In addition, the system supports fault data storage and export (capable of storing 100 historical fault records), facilitating engineers to trace the cause of faults. The average fault diagnosis time is reduced from the traditional 2 hours to 30 minutes, significantly reducing downtime losses in heavy-load scenarios.

Core Components

The stable operation of the ZR120D Grasshopper Conveyor in high-load heavy bulk material scenarios lies in the comprehensive upgrading of its core components around "heavy load-bearing, high wear resistance, and strong stability". From the belt to the drive, from the control system to the hopper structure, each component has undergone heavy-load condition simulation tests at ZOOMRY's Quality Testing Center to ensure long-term adaptation to the continuous operation needs of heavy bulk materials.

Dual Hydraulic Motor Drive System

The hydraulic motors are internationally renowned brand axial piston motors, with a rated working pressure of 25 MPa and a maximum speed of 1500 rpm, featuring "high torque and low noise"—the operating noise is ≤75 dB, 15% lower than that of ordinary gear motors. The motor output shaft is made of 40Cr forging material, with surface nitriding treatment (hardness ≥850 HV), improving impact resistance and wear resistance by 40% and enabling it to withstand instantaneous impact loads during heavy bulk material conveying. The supporting hydraulic power pack has an oil tank capacity of 800 L and is equipped with a triple high-precision filtration device (filtration accuracy: 5 μm), ensuring the hydraulic oil cleanliness reaches NAS Grade 7, reducing wear of hydraulic components. The annual failure rate of the system is less than 0.3%, far lower than the industry average of 1.5%, providing guarantee for the stable operation of the dual motors.

Reinforced Belt Conveying System

In addition to the 20 mm-thick tear-resistant belt, the belt conveying system has undergone multiple enhancements: the drive rollers adopt a "diamond-shaped rubber coating" design with a coating thickness of 20 mm and a friction coefficient of 0.45, ensuring sufficient friction between the belt and the rollers to prevent slipping under heavy loads; the direction-changing rollers have a chrome-plated surface (thickness: 0.1 mm), improving wear resistance by 80% and are equipped with self-aligning bearings to reduce wear caused by belt deviation; the belt tension system uses hydraulic automatic tensioning, which can adjust the tension in real time according to the belt load (tension adjustment range: 5-12 kN), avoiding belt slipping due to insufficient tension or tearing due to excessive tension. The tension response time is ≤2 seconds, adapting to scenarios with fluctuating heavy bulk material loads.

Intelligent Control System

Centered on "easy operation + intelligent diagnosis", the control system is equipped with a 12-inch high-definition color HMI touchscreen, supporting multi-language switching (including English, Russian, Spanish, etc.). The interface layout focuses on the core needs of heavy bulk material operations, retaining only key functions such as "conveying start/stop, belt speed adjustment, fault query, and motor mode switching". Ordinary operators can operate it independently after 1.5 hours of training. The system supports two control modes: local control is completed through the operation panel on the equipment itself, suitable for short-distance debugging and emergency intervention; remote control is equipped with an industrial-grade wireless remote control with a range of 80 meters, whose anti-interference performance meets the IP67 standard—even in heavy bulk material scenarios with high dust and strong vibration, the signal transmission stability remains at 99%. In emergency situations, emergency stop buttons are installed at both ends of the equipment, on the remote control, and in the central control system; pressing any of them immediately cuts off all power, ensuring the safety of heavy bulk material operations.

15 m³ Large-Capacity Hopper

The hopper adopts a "wide-mouth deep-cavity" trapezoidal structure with an effective volume of 15 m³, capable of holding two loads of a single-bucket excavator, reducing the frequency of material replenishment by feeding equipment and improving operational continuity. The inner wall of the hopper is lined with 15 mm-thick wear-resistant manganese steel plates (Mn13), whose wear resistance is 150% higher than that of ordinary carbon steel, providing significant protection against impact wear from heavy bulk materials (such as ore with a single block weight ≤500 kg). The bottom of the hopper is designed as an "inclined diversion outlet" (inclination angle: 18°), and together with the built-in arc-shaped diversion plate, it guides heavy bulk materials to flow evenly onto the belt, avoiding uneven load wear on the belt caused by local accumulation. An optional grid protection net (grid size: 300×300 mm) can be installed at the top of the hopper to prevent oversized materials from entering the hopper and causing blockage, adapting to the "uneven particle size" characteristic of heavy bulk materials.

Convenient Transportation and Efficient Installation

To address the pain points of heavy bulk material projects—"large equipment size, difficult transportation, and long installation cycle"—the ZR120D Grasshopper Conveyor adopts a "modular disassembly + high-proportion pre-assembly" design. While ensuring heavy-load performance, it significantly reduces transportation and installation difficulties, ensuring rapid project commissioning.

Modular Transportation

The equipment is scientifically split into 4 standard modules: "hopper module, drive module, chassis module, and control system module". The size of each module strictly complies with the specifications of a 40ft high cube container (length 12.03 m × width 2.35 m × height 2.69 m): the hopper module is hydraulically folded to a height of 2.5 m and weighs less than 18 tons; the drive module and hydraulic power pack are integrated into a waterproof cabinet with dimensions of 2.2 m × 1.8 m × 2.0 m; the chassis module adopts a lightweight reinforced structure, weighing 22 tons after disassembly, eliminating the need to apply for over-width or over-weight transportation permits. Compared with the traditional "special transportation + on-site welding" mode for heavy-duty grasshopper conveyors, cross-border logistics costs are reduced by 45%, and core components are protected and packaged at the factory to avoid damage caused by jolts and moisture during transportation.

High Pre-Assembly Installation

Before leaving the factory, the equipment has completed 90% of pre-assembly work, including key processes such as belt installation and debugging, hydraulic pipeline connection, electrical wiring laying, and fault self-diagnosis system calibration. It has also undergone a 120-hour full-load test run (simulating a 550 TPH continuous heavy bulk material conveying scenario) to ensure no faults during on-site installation. On-site, only 3 core processes are required: first, module splicing—connecting the hopper to the chassis and the drive module to the belt frame using high-strength bolts (M30, torque: 800 N·m), which can be completed by 2 people in 1.5 hours; second, hydraulic pipeline and electrical connector docking—achieving leak-free connection using quick connectors, taking ≤1 hour; third, no-load test and parameter fine-tuning—checking belt operation, dual-motor synchronization, and fault diagnosis function. A skilled team can complete all installation and debugging and put the equipment into operation within 1 day. ZOOMRY provides a technical manual with step-by-step operation guidelines, which marks special precautions for heavy-load equipment installation (such as bolt tightening torque and hydraulic system venting steps), and also offers online technical support to help solve problems encountered during installation.
