Main Motor System

AC main motor for hydraulic swing beam shear

Reliable AC Main Motor

The standard AC main motor provides stable power output for hydraulic shearing, simple maintenance, and dependable performance for daily sheet metal cutting operations.

Cutting Motion

Swing Beam Action

Swing beam shearing machine cutting principle

Arc Motion

Hydraulic Swing Beam Structure

Swing beam shears use the up-and-down movement of the swing beam to drive the upper blade for cutting. The workpiece is clamped on the worktable while the beam moves downward in an arc path to complete the cut.

Arc Motion Hydraulic Swing Beam Structure

Quick Cutting Through Controlled Arc Travel

The upper blade follows a swing beam path against the fixed lower blade while the sheet remains firmly held. This simple structure supports easy operation, fast setup, and efficient cutting of thin sheet materials.

Safety Systems

Safety Protection

These optional photoelectric protection systems help reduce operating risk around the front feeding area, rear discharge area, and blade working zone.

Rear light curtain protection for guillotine shear
Optional

Rear Light Curtain Protection

Rear photoelectric protection monitors the discharge and backgauge area. When the beam is interrupted, the system can stop dangerous movement and help protect personnel during rear-side maintenance or material handling.

Point-to-point protection for guillotine shear
Optional

Point-to-Point Protection

Point-to-point safety protection is arranged around key risk positions near the shearing zone. It helps detect abnormal entry into the protected area and adds an extra layer of safety for repetitive cutting work.

Front light curtain protection for guillotine shear
Optional

Front Light Curtain Protection

Front photoelectric protection creates a guarded feeding area for operators. It is useful when handling large sheets from the front side and can be configured to match workshop safety practices.
