Key benefits
Why Buyers Choose This Model
Four Claws With Multi-Angle Attachment
Four pads plus an articulating link means the lifter attaches to objects at various angles, which is versatility a fixed three-claw does not have at this capacity.
Iron Alloy Articulating Link
The link is iron alloy rather than aluminium, enhancing overall durability and strength at the joint that carries the entire load.
Thickened Plastic Anti-Slip Latch
Manufactured from thickened plastic with an anti-slip design, maintaining stability and resisting deformation on a lifter rated to 220 KG.
Anti-Oxidation Baking Paint
The surface is treated with a baking-paint process to resist oxidation, maintaining gloss and durability over the life of the tool.
Thickened Rubber-Coated Handle
The handle carries a thickened rubber coating for anti-slip protection and improved grip, which at 220 KG is not a comfort feature.
Application scenarios
Where It Is Used
- Heavy panels handled at an angle
- Large-format glass and tile needing four points of contact
- Curved or non-planar panels at high load
- Specialist industrial handling
Who it is for
The Buyers This Model Suits
Industrial Glass Handlers
Moves large panels that need four points of contact and cannot always be approached flat.
Specialist Installation Crews
Sets panels at angles where a fixed lifter cannot seat, at loads a lighter articulating model will not take.
Distributors With A Specialist Top Tier
The only four-claw lifter here, which makes it the answer to enquiries nothing else covers.
Problems it solves
What It Fixes
High Load Plus Angled Access
Most articulating lifters are light and most heavy lifters are fixed. This one is both.
Articulating Joints Failing Under Load
The iron alloy link is specified for strength at the point that carries everything.
Latches Deforming At Capacity
Thickened plastic with an anti-slip design maintains stability and resists deformation.
Grip Security At 220 KG
A thickened rubber-coated handle is what makes the load controllable rather than merely liftable.

Materials and manufacturing
How This Model Is Made
Parts for the JS8644 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.
- Self-Adhesive Logo Labels: Applied to the product in the position the buyer specifies.
- Multi-Colour Logo Printing: Paint screen printing in any colour, with several colours printed at once.
- Tag And Product Screen Printing: Screen printed tags and product markings, multi-colour capable.

Getting The Best Out Of It
Step 1
Set the articulation to match the panel before applying any pad.
Step 2
Clean and dry all four contact areas; four pads means four chances for a bad seal.
Step 3
Seat all four flat, draw all four vacuums, and confirm each holds before taking weight.
Step 4
Release all four before storage and inspect the iron alloy link and all four nitrile pads as routine.

FAQ
JS8644 Questions
What are the load ratings?
205 KG level suction and 220 KG vertical suction, spread across four pads.
What does the articulating link do?
It lets the lifter attach securely to objects at various angles rather than requiring a flat plane, which is unusual at this capacity. The link is iron alloy for strength and durability.
Why choose this over the JS8643-2?
Articulation. The JS8643-2 is higher rated at 235 KG level but fixed. If the panel is curved or must be approached at an angle, this is the one that will seat.
How is it packed?
One piece per inner box, 10 pieces per master carton at 52 x 40 x 60 cm. Stock colour is yellow.
Is it certified for lifting?
No. These are our own published ratings. No third-party lifting certification exists for this model, and at this capacity that should be settled before you order.
