How does the Cuplock (C-Lock) scaffolding mechanism work?

Cuplock scaffolding uses a fixed lower cup and a movable upper cup. The ledger blade sits inside the lower cup and the upper cup slides down and locks the connection with a hammer tap, creating a rigid joint quickly.

What are the main components of a Cuplock scaffolding system?

The main Cuplock components include vertical standards with cups, horizontal ledgers with forged blade ends, transoms for platform support, braces for stability, spigot pins for height connections, base jacks for leveling, and steel planks for platforms.

What is the load capacity of Cuplock vertical standards and towers?

Cuplock vertical standards generally support safe working loads up to 40–50 kN depending on spacing and height. Towers can be erected up to 6–10 meters with proper bracing and correct installation.

Is Cuplock scaffolding suitable for formwork and slab support work?

Yes. Cuplock scaffolding is widely used for slab support and formwork because it provides fast erection, strong vertical load performance, stable grid layout, and reliable locking.

Do you supply Cuplock scaffolding in bulk with export packaging?

Yes. AMCO Exports supplies Cuplock systems in bulk with export packing, palletization, labeling, and shipment support for India and overseas markets.

Cuplock System for Scaffolding, Formwork & Access

Cuplock Scaffolding System – Technical Specifications

1. Cuplock Vertical Standards

Vertical standards form the main load-bearing framework of the Cuplock system.
Each standard is fitted with fixed bottom cups and sliding top cups at regular intervals.

Length (m)	Outer Diameter	Material Grade	Weight (kg)	Top Cup	Bottom Cup
0.5	48.3 mm	MS / EN-8	2.80 – 3.20	Fitted	Fitted
1.0	48.3 mm	MS / EN-8	5.60 – 6.20	Fitted	Fitted
1.5	48.3 mm	MS / EN-8	8.40 – 9.20	Fitted	Fitted
2.0	48.3 mm	MS / EN-8	11.00 – 12.30	Fitted	Fitted
2.5	48.3 mm	MS / EN-8	13.80 – 15.10	Fitted	Fitted
3.0	48.3 mm	MS / EN-8	16.50 – 18.00	Fitted	Fitted

2. Cuplock Horizontal Ledgers

Horizontal ledgers connect vertical standards and provide lateral stability to the structure.
Forged blade ends ensure secure locking within the cup joint.

Length (m)	Tube Diameter	Ledger End Type	Material Grade	Weight (kg)
0.6	48.3 mm	Forged Blade End	MS / EN-8	2.50 – 2.80
0.9	48.3 mm	Forged Blade End	MS / EN-8	3.60 – 4.00
1.2	48.3 mm	Forged Blade End	MS / EN-8	4.80 – 5.20
1.5	48.3 mm	Forged Blade End	MS / EN-8	6.00 – 6.50
1.8	48.3 mm	Forged Blade End	MS / EN-8	7.20 – 7.80
2.0	48.3 mm	Forged Blade End	MS / EN-8	8.00 – 8.50

3. Cuplock Accessories

Component	Material	Description	Weight
Top Cup	Forged Steel	Locks horizontals	0.40 – 0.50 kg
Bottom Cup	MS / Ductile CI	Fixed node point	0.25 – 0.35 kg
Ledger Blade	Forged Steel	Engages cup joint	0.25 – 0.30 kg
Spigot Pin	Mild Steel	Connects verticals	0.35 – 0.45 kg
Base Jack	Mild Steel	Height adjustment	3.5 – 4.5 kg

For slab shuttering and staging work, the cuplock drop head allows adjustable connections and early striking without disturbing the main support structure.

4. Load Capacity (General)

Component	Safe Working Load
Vertical Standard	40–50 kN (depends on spacing & height)
Ledger	Bracing / support only
Cuplock Tower	Safe up to 6–10 meters with bracing

5. Surface Finish Options

Finish	Benefits
Painted	Economical, corrosion resistance
Hot-Dip Galvanized	Long-term & outdoor use
Powder Coated	Clean, scratch resistant
