Midlock — automatic fixing cone

EC-MIDL-01

An automatic fixing cone that locks the corner castings of two containers stowed side by side, closing the gap between stacks so a whole bay moves as one block under a rolling sea.

Description

Sitting between the corner castings of two containers stowed side by side, this cone locks them to each other so a bay of stacks resists rolling as a single block rather than as independent columns. It engages automatically on landing, keeping operators clear of the stack, and is rated to the same 250 kN tension and 210 kN shear as the semi-automatic twistlock range it works alongside.

Features

  • Automatic fixing — engages as the container lands, no operator at the stack
  • Locks adjacent stacks together across the gap between bays
  • Same 250/210 kN rating as the semi-automatic twistlock range
  • Classification-society approved — GL, BV and CCS

Where it is used

Side-by-side container stowage on vessel decks and in holds; rail wagon stowage where adjacent stacks must act together.

Semi-automatic twistlock

This semi-automatic twistlock engages the moment one container lands on another, so crews only need to pull a toggle to release it — a fast, at-a-glance way to keep ship turnaround moving.

Fully automatic twistlock

Built for the busiest terminals, this fully automatic twistlock locks itself when containers stack and releases on lift — no operator needed anywhere near the stack.

Horizontal twistlock

This horizontal twistlock couples two 20 ft containers end to end into a single 12 m unit, or side by side, and doubles as a fixing point for walkways, masts and other structures on the corner casting's side aperture.
