Semi-Automatic Spreader


The semi-automatic spreader is designed for the handling of 20 ft & 40 ft ISO containers with single or double hook jib cranes, in ports or on vessels. The twistlocks are activated by landing and lifting the spreader from the container by the crane operator. No hydraulic or electric systems are needed.

Standard and Heavy Duty Models are available.  

HD Frames are Additionally Reinforced by75%.


Spreader Bars and Strong Backs

Greenfield Products has a long history of providing Quality Engineering and Manufacturing to the Material Handling Industry. From Sea Ports to Steel Plants and Test Facilities, Greenfield Products Strong Backs and Spreader Bars are used on overhead cranes, rubber tired gantry cranes, fork trucks and ship-to-shore break bulk cranes.  Units have been designed to handle up to 550 Tons.

Manual Spreaders

The LF2020 with manual transmission offers a simple, low-cost solution to handle  low volumes of containers.  As the activation of twistlocks is done by a person pulling on a chain, there is no electrical or hydraulic adaptation to the fork truck.  Securing the spreader to the truck carriage is as simple as pulling a pin or disconnecting a chain.  The quick removal on and off the forks retains the fork truck functionality for general purposes.

Over-height spreader


The Over-Height Spreader is designed to handle goods in a port or rail application where the product is protruding from the top of an open-top container or flat rack.

Container Spreader - Remote Control

The LR4040 is an upgraded version of a Semi-Automatic Container Spreader. The innovation has led to increased production and safety in container port operations. The Radio Controls and Battery Power had proven a great replacement to a semiautomatic spreader Spreader.

Pneumatic Hook Spreader

The Pneumatic Hook Spreader utilizes twenty (20) weblatch hooks divided across two (2) frame sides. The hooks are loaded manually, and then unloaded via a battery-powered remote control. This reduces the labor required to load ships, and allows greater adaptation to various types of bulk and break bulk cargo.

Cantilever Lifting Beam


The new Cantilever Lifting Beam from Greenfield Products offers a wireless, self-contained, battery-powered solution that doesn't require any electrical or hydraulic interface with the crane. The beam's counter-weight is adjusted via remote control, allowing the operator to maintain beam balance during the lift process.

  • Working Load Limit: 9,000 lbs (higher lifting capacities available upon request)
  • Max lift offset from crane hook center: 21'-6"
  • Modular counter-weight system to meet specific job site lifting requirements
  • Rechargeable battery package with 120V AC 3-prong plug
