100% Mechanical Operation: Zero power, no electric motor or hydraulic pump required; relies on crane lifting motion.(An electric drive locking device can also be installed.)
Auto Lock & Unlock System: Twist locks engage on first lift and disengage on second lift without manual intervention.
Low Maintenance Design: No oil changes, leaks, or valve problems; requires only routine lubrication.
Heavy-Duty Steel Construction: Welded high-strength low-alloy steel frame (Q355B) rated up to 41t for daily service.
Floating Twist Locks: Spring-loaded locks adapt to corner-casting tolerance and slightly deformed containers.
Fast Setup & Installation: Hangs from a single crane hook with a four-leg sling; simple to install and move.
Customizable Dimensions: Standard fixed models available with custom dimensions and SWL on request.
A single-point hook with four slings fits virtually any gantry, mobile, truck or ship crane.
Four ISO floating twist locks (ISO 1161/3874) spread the load and allow 10% eccentric load.
CE, ISO 9001 and load-test certified - ideal for low-frequency yards, depots, rail sites and remote no-power locations.

Product Q&A
Q:Does the spreader need electricity or a hydraulic pack?
A:
No. It is 100% mechanical. The crane's own lifting motion, transmitted through the control wire rope and ratchet linkage, rotates the twist locks. This means zero power consumption and no electrical or hydraulic maintenance.
Q:How does it lock and unlock without a worker on the container?
A:
Lowering onto the container and then lifting automatically turns the four locks to the locked position; after the container is placed and the frame settles, the next lift turns them to unlocked. The crane operator completes the whole cycle from the cab.
Q:What capacity do you offer?
A:
Standard models are rated 32t/35t for 20ft and 40t/41t for 40ft, with heavier-duty 45t frames available. All frames are load tested and supplied with a test certificate.
Q:What is the warranty and after-sales arrangement?
A:
A 12-month warranty after delivery applies to main structural and manufacturing defects. Spare lock heads, wire ropes and wear parts are available long-term, with English manuals and online technical support.
