Narrow section fork

1、 What is a narrow section fork?

Narrow section forkAs the name suggests, it is aThe width dimension (cross-sectional height) has been significantly optimized and made very narrowThe telescopic fork. It is a specialized and lightweight variant of the conventional fork.

·core featuresCompared to standard forks, its fork bodyHeight (viewed from the side) and widthAll smaller, overall presentationA slender and elongated form.

·Design objectivesNot to bear extremely heavy loads, but toWithin an extremely limited spaceComplete the access task.

Its intuitive comparison with standard forks:

2、 Working principle and driving mode of narrow section fork

Its basic working principle is similar to that of a regular telescopic fork, both of which extend sequentially through multi-stage fork arms/Retract and store goods. However, due to its lightweight nature, there are differences in the driving method.

1. basic structureSimilarly, they are mostly three levels (fixed fork, middle fork, upper fork), but the plates of each level of fork arm are thinner and the structure is more compact.

2. Mainstream driving methods：

·belt transmissionThis is a very common way. Utilize synchronous belt and pulley transmission. The advantage isSmooth operation, extremely low noise, and low costVery suitable for light and high-speed applications.

·Chain drivenSimilar to belt drive, but with slightly stronger load-bearing capacity and possibly longer lifespan, but slightly inferior in noise and smoothness compared to belt drive.

·Gear rack driveHigh precision and good load-bearing capacity, but the cost and noise may be higher than belt drives.

·Ball screw driveCan provide jiHigh positioning accuracy and smoothnessBut the cost is the highest and the speed is usually not as fast as belt transmission. Commonly used in situations where precision is strictly required.

Narrow section forks are usually made ofservo motorDrive to achieve precise position control.

3、 The core advantage of narrow section forks

1. jiExcellent spatial adaptability (main advantage)This is the fundamental reason for its existence. It can be easily embedded into very narrow gaps reserved inside shelves, production line equipment, or other machinery for operation, which standard forks cannot achieve.

2. lightweightDue to the reduction of structural materials, the weight of the entire mechanism has significantly decreased. This makes the lifting mechanism that drives it (such as the lifting gantry of stacker cranes and four-way shuttle cars) have a smaller load, which can achieveHigher operating speed and accelerationReduce energy consumption.

3. High speed and high precisionThe lightweight volume combined with servo drive can achieve fast expansion and contraction cycles and precise stopping, especially suitable for high-frequency and fast-paced "goods to people" picking operations.

4. low noiseEspecially when using belt drive, the operating noise is much lower than that of traditional heavy-duty chain forks, improving the working environment.

4、 Typical application conditions

Narrow section forks are designed for high-performance, high-density warehousing and logistics scenariosideal choice：

1. Dense automated vertical warehouse for material boxes

·Scene descriptionThe storage unit is a standard material box or cardboard box, with narrow shelf aisles and small gaps between cargo compartments.

·Application devices：Bin StackerandFour-way shuttle car.

·Why is it applicableThe material box stacker and four-way shuttle are designed to be very compact, and the space on their lifting gantry is extremely limited. The narrow section fork is the only option that can be installed on it and complete the storage and retrieval of deep level material boxes. It can accurately pick and place individual material boxes from dense cargo compartments.

2. "Goods to People" picking system for light goods

·Scene descriptionSorting centers in industries such as e-commerce, pharmaceuticals, and clothing need to quickly and frequently retrieve thousands of bins from high-density warehouses and deliver them to picking workstations.

·Application devices：Multi layer shuttle car.

·Why is it applicableThe multi-level shuttle car runs at high speed on the shelf track, and its cargo platform is very small. The narrow section fork is its core actuator, responsible for accurately pushing out or pulling the material box into the cargo space during high-speed driving, meeting high throughput requirements.

3. Automated loading and unloading on the production line

·Scene descriptionAt automated production lines and assembly lines, mechanical arms or specialized equipment are required to feed robots or workstations from material racks.

·Application devices：Joint robot arm end toolorCustomized loading and unloading mechanism.

·Why is it applicableProduction line space is usually precious. The narrow section fork can serve as an "extended arm" that can be directly installed on the sixth axis of the robot, extending into the narrow space inside the equipment to retrieve and place workpieces, fixtures, or small material boxes.

4. Other special scenarios

·Intensive storage warehouseEven for pallet warehouses, if narrow aisle shelves or mobile shelves are used, their access space may be limited. In this case, lightweight narrow section forks are the solution.

·clean environmentFor industries such as food, medicine, and electronics, equipment needs to meet dust-free requirements. The narrow section fork has a simple structure, is easy to clean, and can be made of stainless steel material to meet cleanroom standards.

·freezerIn cold chain logistics, equipment needs to be resistant to low temperatures. The driving components of narrow section forks, such as servo motors and belts, can be specially designed to adapt to low-temperature environments and achieve automated access.

summary

In conclusion,Narrow section forkIt's to solve the problemAn efficient solution born from the specific requirement of achieving lightweight automated storage and retrieval of goods in a compact space. When your application scenario involves high-density storage and high-frequency circulation of material boxes and small items,Narrow section forkAlmost a critical component that can or cannot be replaced.
