The SQZ160A.3 8 ton knuckle boom crane is a compact, high-efficiency folding boom lifting solution engineered for urban maintenance contractors, emergency response teams, factory facility managers, and small logistics operators requiring agile, precise lifting in tight spaces. As a premium folding boom truck mounted crane, it delivers a maximum 8000kg (8 ton) lifting capacity and 16 t×m rated lifting torque, paired with full 360° continuous slewing for unmatched maneuverability in confined urban and industrial environments. With an ultra-compact 1200mm installation footprint and lightweight 3150kg high-strength steel body, this hydraulic knuckle boom crane balances robust lifting performance with space-saving folding design, powered by a 30kW hydraulic system that ensures fast, responsive boom control for medium to heavy-duty lifting tasks. It is purpose-built to deliver consistent safety, flexibility, and durability across diverse commercial lifting and emergency operations.
The core advantage of this 8 ton knuckle boom crane is its innovative folding boom structure, which retracts to a compact footprint for easy transport and operation in narrow urban streets, high-rise construction sites, and cramped factory yards. Unlike telescopic models, its articulated knuckle boom delivers exceptional vertical and horizontal maneuverability, enabling precise load positioning in spaces where traditional boom cranes cannot operate.
The optimized hydraulic system operates at 28MPa rated pressure with a 45 L/min flow rate, delivering fast, smooth, and precise boom response with minimal energy consumption. The 150L hydraulic oil tank supports continuous, stable operation for extended work cycles, while integrated overload protection enhances operational safety.
With a 3150kg self-weight and 1200mm minimal installation space, this compact 8 ton truck crane easily mounts on most medium-duty trucks without compromising vehicle payload capacity. Its lightweight design reduces fuel consumption and vehicle wear, making it a cost-effective choice for daily commercial operations.
Built with high-strength steel for long-term durability, the crane features integrated safety systems including hydraulic stabilization, overload protection, and smooth slewing control. Its intuitive control layout reduces operator fatigue and enhances lifting accuracy in complex, high-pressure environments such as emergency rescue operations.

This 8 ton knuckle boom crane is ideal for commercial lifting applications including:
Urban Construction & Municipal Maintenance: Lifting building materials, installing streetlights, and maintaining utility infrastructure in narrow urban streets and high-rise sites.
Industrial & Factory Operations: Transporting machinery, raw materials, and production components within cramped factory floors and warehouses.
Emergency Rescue & Disaster Recovery: Fast deployment for lifting debris, equipment, and relief supplies during natural disasters or industrial accidents.
Small Port & Logistics Hubs: Light to medium cargo handling, container positioning, and loading/unloading in small-scale ports and storage facilities.
To ensure safety and long-term reliability for this folding boom truck mounted crane, professional operators must follow strict protocols:
Pre-Operation Checks: Park on firm level ground, fully extend outriggers with support pads, confirm all control levers are neutral before PTO engagement, and maintain a 10m minimum safe distance from high-voltage lines.
Safe Lifting Protocols: Adhere strictly to the load chart, never exceed the rated lifting capacity for the current boom radius and angle. Avoid sudden movements, never lift loads over personnel, and never leave a suspended load unattended.
Routine Maintenance: Lubricate boom pivot points and hydraulic cylinder pins before each use, inspect hydraulic hoses, bolts, and structural components for wear regularly, and follow the manufacturer’s guidelines for hydraulic oil replacement. Only trained personnel may perform hydraulic system maintenance.
This 8 ton knuckle boom crane has a maximum safe working load of 8000kg (8 ton) with a 16 t×m rated lifting torque. Exceeding this capacity risks structural failure and voids the product warranty.
