Straight Bed Shear/Gantry Shear

A straight bed shear, also called a gantry shear, is a large hydraulic scrap processing machine built to cut heavy and mixed scrap down to furnace charge size. It is the workhorse of a yard that receives an unpredictable material mix, because its wide press box takes almost anything without pre-cutting.

What it cuts

LMS, HMS, structural scrap and mixed heavy scrap. Its versatility across scrap grades is the main reason it stays the default choice for yards that cannot control what arrives at the gate. The machine is built with high structural strength for long life under the shock loading that heavy scrap cutting produces.

Why the wide press box matters

A wider box accepts long and awkward pieces straight from the grab, without an operator first cutting them down to fit. That removes an entire handling step from the yard. On material like structural sections, rail and heavy plate, the time saved on pre-cutting is usually larger than any difference in cutting cycle between machines.

Output density

The machine applies high compression before shearing, so the cut material comes out dense rather than loose. Side compression is available as an option where you need higher density still, either to meet a mill specification or to cut freight cost on outbound loads.

Features

• Wide press box suitable for multiple varieties of scrap
• High compression after shearing, with side compression available as an option
• PLC operation, automated controls and remote operation
• Automatic operator less running once the cycle is set
• Large flow logic valves with independent filtering and cooling
• Low electricity consumption per tonne of steel processed
• Automatic lubrication and sensors for movement automation

Hydraulic reliability

On a machine that runs long cycles under heavy load, hydraulic oil temperature and cleanliness determine service life more than anything else. Large flow logic valves with independent filtering and cooling keep the oil within its working range instead of relying on ambient conditions, which is what allows sustained output through a full shift in Indian summer conditions rather than a derated afternoon.

Choosing between shear types

• Straight bed or gantry shear for heavy and mixed scrap where versatility matters most
• Baler shear where the feed is light and needs compressing before it can be cut usefully
• Alligator or tiger head shear for smaller volumes and profile cutting
• Container shear for low volume, portable and light thin material

Specifying a machine

Specification follows from your material mix, the largest section you need to cut, tonnes per shift and the charge size your buyer or furnace requires. Tell us those and we will size the machine and plan the feeding and discharge arrangement around it, since a shear only achieves its rated output if material arrives and leaves without pause.
