XCMG SQZ3500 Knuckle-Boom Crane

Overview

The XCMG SQZ3500 is a flagship model in XCMG’s large-tonnage knuckle-boom crane range. The series is built around high lifting capacity, combined with a low body height for working in restricted headroom, powered boom extension under load, fine combined movements and all-round lifting capability. XCMG states the range covers lifting capacities from 40 t to 220 t and targets heavy, precise lifting inside factories and tunnels.

With a short body, low overall height and a 10 t counterweight carried on the vehicle, the SQZ3500 is positioned for sites where the crane must move between workshops and work in confined spaces.

Key Features

• Six-section boom with twin first-stage push — strong lifting and powered extension capacity, with a wide working radius that reduces the number of vehicle repositioning moves.
• Sequenced, cushioned telescoping — sequenced telescopic cylinders with cushioning keep boom movement smooth and precise.
• Retractable counterweight — a retractable counterweight system with up to 10 t of onboard ballast that travels with the vehicle and can be fitted and removed quickly.
• Twin high-torque slewing reducers — strong slewing power and effective braking for smoother, safer slewing.
• Integrated box-section frame with six outriggers — all-round working capability, with side lifting up to 50 t.
• Proportional hydraulics — fine control and combined movement, a differential boom circuit for higher efficiency, and XCMG wide-temperature hydraulic oil for operation from -23 °C to 88 °C.
• Electrical safety package — moment limiting, anti-overturning control, working warning and night-lighting systems, plus wireless remote control.
• Road-friendly dimensions — low own weight within legal limits, a short body with a small turning radius and low height so the crane can enter workshops and factory buildings.

Applications

Lifting and hoisting, construction sites, and factory and plant handling.
