Core Lifting Performance & Technical Specifications

Dynamic Load Capacity & Working Height

This mobile spider crane delivers a maximum lifting capacity of 3 tons, with a maximum working height of up to 11m. Its load capacity changes dynamically with boom extension: it maintains a 400kg rated load at 10m working height, which is fully suitable for more than 80% of mainstream low-altitude lifting tasks on job sites.

Multi-Scene Adaptability With Interchangeable Attachments

Versatile Tools for Diverse Operations

Widely compatible with multiple auxiliary equipment, it works perfectly with an electric vacuum lifter for glass curtain wall installation, and excels at cargo handling on construction sites. It also supports interchangeable attachments such as a man basket, to support safe manned high-altitude work for maintenance and fit-out projects.
