How to Buy a Container Spreader: Types, Specs, Brands & Prices
A container spreader is the interface between the crane and the box, and one of the most safety-critical pieces of port equipment a terminal will buy. Get it wrong and no amount of crane capacity helps you. This guide covers every decision a buyer needs to make — type selection, compatibility, specs verification, brand choice, and pricing — so you arrive at a deal knowing exactly what you're buying.
Types of Container Spreaders
There are four main spreader types, each suited to different operations and crane configurations.
| Type | Length range | Best for | Price range (used) |
|---|---|---|---|
| Fixed spreader | 20 ft or 40 ft (single size) | High-volume terminals handling one container size | €5,000 – €30,000 |
| Telescopic spreader | 20–45 ft | Mixed container traffic, RTG/RMG/STS cranes | €40,000 – €120,000 |
| Twin-lift spreader | 20 ft × 2 or 40 ft × 2 | High-productivity STS cranes moving two 20 ft boxes at once | €100,000 – €250,000 |
| Tandem spreader | Two 40 ft frames in tandem | Ultra-high-throughput terminals, large STS cranes | €200,000 – €450,000+ |
Fixed spreaders make sense only if your terminal handles a single container size almost exclusively. For any mixed operation, a telescopic spreader is the default choice. Twin-lift adds complexity — the crane must be rated for it and the headblock must match — but the throughput gain can justify the investment at busy terminals.
Compatibility: Which Spreader Fits Which Crane?
Before you look at any listing, confirm what your crane's headblock accepts. Mismatches here are expensive mistakes.
| Crane type | Typical spreader type | Notes |
|---|---|---|
| Ship-to-Shore (STS) | Telescopic or twin-lift | Headblock interface is brand-specific; verify bolt pattern and pin configuration |
| RTG (Rubber-Tyred Gantry) | Telescopic | Most RTGs use a standard Bromma- or Stinis-compatible headblock |
| RMG (Rail-Mounted Gantry) | Telescopic or fixed | Fixed spreaders common on automated RMGs for speed |
| Reach stacker | Fixed or rotatable telescopic | Reach stacker spreaders rotate ±5°; not interchangeable with crane spreaders |
| Mobile Harbour Crane (MHC) | Fixed or telescopic with spreader beam | Lifting harness varies by MHC model; confirm with crane OEM |
Key Specifications to Verify
Every spreader listing should be checked against these specifications before you make an offer:
- Safe Working Load (SWL): Expressed in tonnes. Must match or exceed the heaviest container you handle. Standard is 36 t, heavy-duty versions go to 45 t or 50 t.
- Twistlock type: Manual, semi-automatic, or fully automatic. Automatic twistlocks add cost but reduce cycle time and improve safety. Confirm the type is compatible with your operational standard.
- Headblock interface: The physical connection between spreader and crane hoist. Defined by pin diameter, bolt pattern, and electrical connector type. Never assume universality — get the drawing.
- Weight of the spreader: Deducted from the crane's SWL. A heavy twin-lift spreader can consume 8–12 t of available lift capacity.
- Control system: PLC brand and age matter for spares and support. Siemens and Allen-Bradley are common; check if the firmware is still supported.
- Flipper condition: The guide flippers take abuse. Inspect for cracks, worn pivot points, and bent frames. Replacement flippers can cost €2,000–€8,000 per corner.
- Structural inspection certificate: Requires a third-party structural assessment (SGS, Bureau Veritas, Lloyd's). Never buy a used spreader without one.
Brands: Bromma, Stinis, Elme, and RAM
The spreader market is dominated by a small number of manufacturers, each with a distinct market position.
Bromma (Kalmar): The global market leader by volume. Bromma spreaders are found on terminals on every continent. This means excellent parts availability, a wide global service network, and strong resale value. The downside: Bromma equipment is priced at a premium, and some older Bromma models require proprietary parts that only the manufacturer can supply.
Stinis: A Dutch manufacturer specialising in twin-lift and high-performance spreaders for STS cranes. Stinis is the preferred brand for many European terminal operators upgrading to twin-lift. Parts are available but the network is smaller than Bromma's — plan for longer lead times outside Europe.
Elme Spreader: The dominant supplier for reach stacker spreaders, with strong presence in Europe and Asia. Elme's crane spreaders are less common, but their reach stacker attachments have an excellent reputation for durability. If you're buying a spreader for a reach stacker rather than a crane, Elme should be on your shortlist.
RAM Spreaders: A UK-based manufacturer producing rugged spreaders for harsh environments. RAM is well-regarded in bulk terminal and smaller port operations. Less common in major container terminal applications but competitive on price.
Pricing Overview
Used spreader prices vary significantly by type, age, and condition. The ranges below reflect typical market prices for spreaders in serviceable condition with a valid structural certificate:
- Fixed spreader (20 or 40 ft): €5,000 – €30,000
- Telescopic spreader (20–40 ft, crane-mounted): €40,000 – €120,000
- Twin-lift spreader: €100,000 – €250,000
- Tandem spreader: €200,000 – €450,000+
A Bromma telescopic from a major terminal in good condition will sit at the top of these ranges. A lesser-known brand or a spreader sold without certification will be at the bottom — but factor in the cost of certification (€3,000–€8,000) before celebrating a low price.
What to Ask the Seller
Before committing to a purchase, get answers to the following:
- What is the spreader's operational history — which crane, which terminal, how many cycles per year?
- Is a current structural inspection certificate available, and from which inspection body?
- What is the PLC make and model, and is the software version documented?
- Are spare parts included in the sale (twistlocks, flippers, wear parts)?
- What is the headblock pin diameter and bolt pattern — can you provide the interface drawing?
- Has the spreader been involved in any overload incident, and is there documentation?
- Is disassembly and loading included, or is the spreader sold as-is where-is?
A seller who cannot answer these questions clearly is a seller worth walking away from. Spreaders operate under life-safety conditions — documentation matters.
Buying the right spreader is one of the higher-stakes port equipment decisions a terminal makes, so take the time to verify before you commit.
