GC-300A | ｜ツールチェンジャーのメーカー｜ビー・エル・オートテック株式会社

Load capacity：300kg(2,940N)
Optional parts can be equipped

The BL QUICK-CHANGE Model GC-300A is a device for automatic tool changing, specially designed for changing material handling welding guns or guns with built-in transformers in a spot-welding line. Primary current, air pressure and electrical signals (Servo) modules can be selected for the GC-300A.The GC-300A provides increased production line efficiency and cost effectiveness.

Master plate Attachments

・2 insulation pins
・6 insulation washers
・6 insulation pipes
・6 bolts（M10×30）
・1 locating pin
・6 plain washers

Features of GC-300A

Unidirectional cable and hose

The power and control cables and the pneumatic hose are oriented in a single direction.

The primary current module contains a floating mechanism

The primary current module is equipped with a self-cleaning function and a floating mechanism.

Self-sealing coolant ports

The check valves of the circulating coolant ports are equipped with a PTFE sleeve to prevent liquid spillage.

Superior fail-safe locking mechanism

BL’s unique lock/unlock mechanism contains a mechanical fail-safe feature which does not allow the Master and Tool plates to uncouple if the air pressure is shut off.
