Safety switches preserve productivity
The SensaGuard will shut down a machine if a failure occurs before there is a demand on the safety device, which improves machine operator safety.
Safety interlock switch adds escape release
Improved safety provision for machine operators is provided by Allen-Bradley Guardmaster's introduction of a new escape release facility for its TLS-GD2 safety interlock switch.
The Sliding Bolt Actuator protects operatives and maintenance staff from injury by ensuring that the actuator key of a safety interlock switch does not engage and allow potentially dangerous machinery to start-up.
The actuator is particularly useful in applications where, for example, a safety switch is used as the main interlock on the gate of an enclosure housing equipment which itself is unshielded.
Without the facility for locking-out the actuator, the gate could be closed in error, presenting a danger to those working within.
However, by padlocking the Sliding Bolt Actuator the interlock switch cannot be engaged and mechanical start-up is prevented, even if the gate is closed inadvertently.
The design of the Sliding Bolt Actuator ensures the maximum safeguarding by providing the facility for up to three padlocks.
This means that up to three operatives could be working in the same safety sensitive area at any one time.
Each of the operatives would have his own unique key to one of the padlocks on the actuator and each would signify completion of his work in the sensitive area by removing his padlock.
Only when all the padlocks were removed would the sliding bolt actuator be freed, enabling normal working to resume.
The Sliding Bolt Actuator has been conceived with robust applications in mind.
Its construction, a solid aluminium extrusion with durable satin anodised finish, reflects this.
The integrated design includes a removable handle that accommodates an anchor point for rope attachment.
It also offers the flexibility of 4 fixing positions to suit actuator entry for Trojan 6, MT-GD2, Trojan GD2 and TLS-GD2 safety interlock switches.
