JS8643-1 Three-Claw Vacuum Suction Cup (Export Model)
The export version of the three claw, rated 145 KG level suction and 155 KG vertical, in yellow.

Product Overview
The export version of the three claw, rated 145 KG level suction and 155 KG vertical, in yellow. It shares the JS8643's construction throughout, with an exterior designed to meet international market requirements, and it is another model where the vertical figure exceeds the horizontal.
Why Buyers Choose This Model
155 KG Vertical Suction
Higher than its own 145 KG level figure, which matters because panels are more often carried upright than lifted flat on site.
Same Construction As The JS8643
Precision-pressed aluminium alloy, triangular disc support, 7 mm thickened nitrile pad, engineering ABS latch and premium nitrile rubber throughout.
Export-Specific Exterior
A uniquely designed exterior to meet international market expectations, without changing the mechanism underneath.
Increased Support Surface
A sufficiently large support surface ensures stable support during handling and reduces effort, adapting to objects of different sizes.
Where It Is Used
- Export markets with their own appearance expectations
- Panels carried upright where the vertical rating governs
- Household and industrial smooth-surface handling
- Mid-tier of a three-claw range
The Buyers This Model Suits
Export Distributors
Sells into markets where the standard domestic exterior is not what buyers expect.
Glazing Crews Carrying Upright
155 KG vertical is the figure that applies to most real site handling.
Distributors Needing A Middle Three-Claw
Sits between the 115 KG JS8643 and the 235 KG JS8643-2.
What It Fixes
Appearance Expectations By Market
The export exterior exists because a lifter that looks wrong does not sell, regardless of its rating.
Upright Handling Being The Norm
The vertical rating is higher here, which suits how panels are actually moved.
Panels Of Varying Size
The increased support surface adapts to different object sizes rather than being optimised for one.
How It Is Built
Alloy Monolithic Construction
Similar to the JS8643, the JS8643-1 is crafted from aluminum alloy through precision pressing, providing exceptional pressure resistance and anti-drop capabilities. This design ensures stability and durability during operations.
Triangular Disc Support
Just like its counterpart, the JS8643-1 incorporates a triangular disc support system, distributing force through triangular support to enhance stability and prevent inadvertent detachment.
Thickened Rubber Pad
The JS8643-1 features the same 7mm thickened rubber pad as the JS8643, offering powerful suction and secure adherence. Its outstanding adhesion performance remains consistent across various surfaces.
Engineering ABS Latch
Similar to the JS8643, the JS8643-1 is equipped with an engineering-grade ABS latch featuring anti-slip grooves, ensuring effortless operation and dependable support. This design enhances ease of use and operational efficiency.
Anti-Slip Handle Design
Prioritizing user experience and safety, the JS8643-1 incorporates an anti-slip handle design, providing a comfortable grip and ensuring increased safety during usage.
Simple Locking Mechanism
The JS8643-1 boasts the same user-friendly locking mechanism as the JS8643, requiring a single press and release to swiftly complete the operation, streamlining the process.
Premium Nitrile Rubber
Just like the JS8643, the JS8643-1 employs high-quality nitrile rubber known for its exceptional oil, abrasion, and heat resistance, along with strong adhesive properties, ensuring lasting performance across various conditions.
Increased Support Surface
The JS8643-1 maintains a sufficiently large support surface, ensuring stable support during handling and reducing effort. Its adaptability to objects of different sizes enhances operational efficiency.

How This Model Is Made
Parts for the JS8643-1 are produced in our own workshops in Jinli Town, Zhaoqing. This model uses both routes: its moulded components come off our five horizontal and three vertical injection moulding machines, and its metal parts come off our fifteen automatic punching machines, nine automatic lathes and three welding machines. Tooling is designed and cut in our own mould room, which is why a change to this model does not queue behind another factory's schedule.
Quality Control
- Every model is weighed against its declared net weight during production, so the carton weight on your packing list matches what arrives.
- Stamped parts are produced in house on 15 automatic punching machines and 9 automatic lathes, so dimensional consistency is controlled at source rather than inspected on arrival.
- Moulded parts come off 5 horizontal and 3 vertical injection moulding machines running up to 10,000 mould open-and-close cycles per day, with tooling maintained in our own mould room.
- The quality management system was certified to ISO 9001:2015 in August 2023, with a certificate valid to 31 July 2026.
- Cartons are counted against the packing list as they are loaded into the container at our own factory door.
Certifications
The quality management system was certified to ISO 9001:2015 in August 2023, under standard GB/T19001-2016, for the manufacture and sale of glass caulking guns and sealant guns. The certificate on file runs to 31 July 2026; ask us for the current renewal status before relying on it. A TUV Rheinland assessment was obtained in 2016.
Customisation Options
- Aluminium Tube Anodizing And Colouring: More than 10 colours available; the surface can be given a frosted texture.
- Aluminium Tube Painting: Up to 10 colours with customisable patterns.
- Aluminium Tube Laser Engraving: Engraved logos, text and patterns on stamped fittings and aluminium tubes.

Getting The Best Out Of It
Step 1
Clean and dry all three contact areas on the panel.
Step 2
Seat all three pads flat before operating any latch, so none starts partly loaded.
Step 3
Use the 155 KG vertical figure for upright carrying, with margin for surface condition.
Step 4
Release all three vacuums before storage and inspect each pad before the next lift.
