Engineering & Technical Overview
The Cross Bar Limit Switch Single Speed is a mission-critical crane safety limit switch engineered by CMK Electro Power to provide fail-safe over-travel protection for hoisting, lowering, long-travel, and cross-travel crane motions. Encased in a rugged IP55/IP65 cast aluminium or pressed steel housing, this Rotary Geared Shunt switch features heavy-duty silver-cadmium double-break contact blocks and positive-action mechanism. Designed to interrupt control circuits and trip main power contactors before mechanical end-stops or extreme hook heights are breached, preventing catastrophic crane collisions and rope over-winding.
Industrial Applications & Machinery
Overhead EOT crane main and auxiliary hoist over-hoisting and over-lowering limits.
Long-travel (LT) and cross-travel (CT) crane motion deceleration and emergency cutoff.
Electric wire rope hoists, winches, gantry cranes, and automated lift platforms.
Steel rolling mills, furnace charging cranes, and heavy scrap handling cranes.
Automated industrial machinery requiring precise rotational or linear position cutoff.
Key Operational & Safety Benefits
Fail-Safe Circuit Interruption
Snap-action contact mechanism guarantees immediate circuit disconnection upon threshold contact.
Rugged IP-Rated Enclosure
Heavy cast metal body shields electrical contacts against dust, oil mist, and outdoor weather.
High Contact Current Rating
Silver-alloy contacts handle heavy inductive motor control currents without welding.
Simple Field Adjustment
External adjustable cams or weighted levers allow quick, micrometer-precise tripping calibration.
ISO 9001
2015 Tested: Conforms to IS 13947 / IEC 60947 electrical safety standards for heavy industrial gear.
Statutory & International Compliance Certifications
Official CMK Electro Power statutory accreditations, international test compliance, and quality standard certificates.
