Crane Height Limiter Export Case to India

We customized 120 sets of 4-stage rotary limit switches using high-strength die-cast aluminum housings and precision copper contacts for long-term durability under heavy loads. Each unit was tested for protection rating and electrical performance, including functional simulation. We provided multilingual installation guides, wiring diagrams, and remote technical support to help the customer install and commission the products quickly and efficiently.

01-Project Overview

In May 2023, our company successfully delivered a batch of crane height limit switches to a crane manufacturing enterprise in India. The devices were applied to bridge and gantry crane systems to ensure lifting safety. The client had strict requirements for the sensitivity, durability, and protection level of the limiters. This project helped enhance the overall safety of their cranes before shipment and met local industrial standards for lifting equipment safety.

02-Industry Background

With the increasing frequency and capacity of lifting operations, limit switches have become an essential safety component in modern crane systems. Height limiters prevent the hook from over-traveling and crashing into the hoist, reducing the risk of accidents. They are now considered standard safety equipment to ensure the safe and stable operation of lifting systems.

03-Customer Requirements

High-precision and fast-responding limit switches for frequent lifting operations
Support for multi-stage limit control including pre-warning slowdown and final cutoff
Dustproof and waterproof enclosure to withstand humid and outdoor environments
Compatible mounting interface for integration with various crane models
Delivery within 45 days along with wiring diagrams and installation manuals

04-Solution

Professional Model Selection: Recommended optimal switch types and contact combinations based on lifting height and hook design
Standards Compliance: All switches conformed to IEC standards and local electrical safety codes
Technical Documentation: Provided CAD drawings, wiring schematics, and multilingual user manuals for easy integration and maintenance
Ongoing Support: Offered on-site installation guidance, spare parts supply, and remote troubleshooting services
Reliability Testing: Each product passed fatigue testing, environmental adaptability testing, and electrical aging validation before delivery

05-Project Highlights

4-stage limit structure providing slowdown, alarm, and power-off protection
High protection level suitable for harsh industrial environments
Universal mounting structure compatible with various crane types
100% factory-tested for electrical consistency and mechanical accuracy
On-time delivery with full technical documentation and after-sales support
