IntroductionRecently, a team from a well‑known domestic forklift attachment enterprise visited Suzhou JST Automation Technology Co., Ltd. for an on‑site factory audit and in‑depth technical exchange. The visiting team toured the production workshop and product exhibition area to inspect the whole workflow of electric cylinder R&D, manufacturing and performance testing. Both sides held thorough discussions on topics including the electrification upgrading trend of the forklift attachment industry, practical application pain‑points of electric cylinders and customized solution development, laying a solid foundation for future industrial collaboration.
Industry Background
With the rapid development of warehousing, logistics and intelligent manufacturing, forklifts and their diverse attachments are accelerating the transition toward electrification, intelligence and cleanliness. While the electrification rate of complete forklift units keeps rising, a large number of actuators still rely on hydraulic technology. Drawbacks of conventional hydraulic drive systems such as oil leakage, cumbersome maintenance and limited control accuracy have become increasingly prominent. Their inherent weaknesses in energy efficiency, leakage prevention and maintenance have turned into the final bottleneck restricting the full electrification of forklifts.
Replacing hydraulic systems with servo‑controlled electric cylinders to realize the “hydraulic‑to‑electric” transformation of actuators is critical to breaking this bottleneck. As high‑performance linear actuators, electric cylinders are increasingly becoming core drive components for upgrading forklift attachments.
Typical Applications of Electric Cylinders on ForkliftsElectric cylinders can substitute for part of hydraulic cylinders to meet diverse mechanical drive requirements. They are widely used for supporting attachments of various electric forklifts as well as AGV/AMR automated forklifts.
Fork Carriage Side Shift
This function enables lateral movement of fork tines to facilitate fork picking, stacking and positioning, and is especially indispensable for narrow‑aisle and high‑bay warehousing. The electric side‑shift system realizes left‑right side shift of fork tines and adjustment of fork spacing, allowing precise adaptation to palletized goods of different specifications. Adopting electric drive, the system delivers high positional control accuracy and smooth side‑shift motion, effectively eliminating fork tine jitter and cargo collision risks caused by oil‑pressure fluctuations in traditional hydraulic solutions.
Conventional hydraulic side‑shift systems suffer from response lag and coarse displacement control. Operators often need repeated forward‑and‑back fine‑tuning to align with pallets, slowing down operation cycles and raising collision hazards.
With the electric drive solution, fork tines can reach the preset travel position in a single movement without repeated adjustments. This greatly improves inbound and outbound efficiency and reduces operator workload.
Attachment Tilting and Tilting‑Flip Mechanisms
Electric cylinders drive clamps, rotators and tippers for angle adjustment, suitable for clamping and transporting special materials such as paper rolls, drum‑shaped goods and boxed cargo. Forward and backward mast tilt determines the fork’s loading/unloading angle and load stability. In practical operations, forklifts frequently work under heavy‑load and load‑holding conditions with relatively small motion ranges but extremely high reliability requirements.
Among common failures of forklift hydraulic systems, tilt cylinders are one of the high‑failure‑rate key components, whose faults account for a considerable proportion of total hydraulic system breakdowns.
Electric cylinders feature compact structure, small installation footprint, smooth operation and near‑zero maintenance. When handling heavy‑load goods such as paper rolls and drums, electric cylinders drive the mast through small‑range forward and backward tilting, achieving stable and reliable load‑holding performance. Cargo surfaces are free from oil contamination, and the tilting mechanism requires no special maintenance even after long‑term operation.
Light‑Duty Lifting Actuators
They assist local lifting compensation for attachments, enable automatic docking in warehousing scenarios when paired with AGV unmanned forklifts, and support bus connection to intelligent control systems.
Compared with traditional hydraulic solutions, electric cylinders applied to attachments, mast tilting and side‑shift mechanisms require no hydraulic power stations or oil pipelines, fundamentally eliminating oil‑leakage risks.
Direct electric drive delivers higher energy efficiency and effectively extends the endurance of battery‑powered complete machines. Supporting programmable closed‑loop control over position, speed and thrust, electric cylinders feature fast response and precise positioning. They are better suited for intelligent scheduling requirements of unmanned forklifts and significantly cut subsequent maintenance workload.
Core Advantages of JST Electric Cylinders
Considering industry characteristics of forklift attachments including compact on‑board installation space, heavy vibration and impact, mixed indoor‑outdoor workshop operating conditions and high‑frequency reciprocating cycles, JST has developed dedicated electric cylinder products for on‑board equipment, addressing industry demands in terms of structure, protection, control and customization capability.
PART.01 Compact Structure for Confined Spaces
JST offers multiple product series including integrated, miniature and multi‑stage electric cylinders. The integrated motor‑cylinder design reduces overall dimensions, satisfying layout constraints of limited installation space for forklift attachments. Multiple mounting interfaces are supported, facilitating retrofitting of existing complete machines and development of new models.
PART.02 High‑Grade Protection & Impact Resistance for Harsh Working Conditions
Products achieve high‑level dust‑proof and water‑proof protection, resisting workshop dust, temperature variation and on‑board vibration and impact. Structural design is optimized for frequent start‑stop and reciprocating forklift operations, delivering strong impact resistance to guarantee long‑term stable attachment performance for indoor warehousing and selected outdoor working scenarios.
PART.03 Closed‑Loop Control Empowering Intelligent Forklifts
High repeat positioning accuracy enables multi‑dimensional controllability of speed, position and thrust. Compatible with mainstream industrial buses such as CANopen and PLC, the electric cylinders can be directly interfaced with control systems of AGVs and automated forklifts to realize digital management of attachment motions and accelerate implementation of unmanned logistics equipment.
PART.04 Clean & Energy‑Saving with Reduced Operation and Maintenance Costs
Fully electric drive removes risks of hydraulic oil leakage, making the cylinders suitable for cleanliness‑critical warehousing scenarios in food, pharmaceutical and electronics industries. The simplified structure eliminates numerous vulnerable parts such as hydraulic pipelines and sealing components, drastically cutting maintenance labor, later‑stage servicing and oil‑consumable costs while improving the overall lifecycle value of equipment.
PART.05 Non‑Standard Customization for Individualized Requirements
Equipped with a complete R&D, processing and testing system, JST delivers rapid customized development according to practical attachment parameters including thrust, stroke, speed, voltage, installation dimensions and special protection requirements. Product offerings cover mid‑low‑thrust through heavy‑duty high‑thrust grades to meet differentiated project requirements for attachments of different‑tonnage forklifts. JST provides end‑to‑end technical support from model selection and prototype testing to mass‑production roll‑out.
