HOWO Heavy Duty Folding Hydraulic Telescopic Knuckle Boom Truck With GSQS250-5 Crane

Safety: Often includes a Load Moment Indicator (LMI) and an overwinding protection device.

Efficiency: Features a double-pump confluence system to increase winch speed and improve operating efficiency.

Control: Typically offers a Ground Control System as standard, with options for a Top Seat Control or Remote Control.

Technology: Includes an automatic hook retracting device to save setup time and prevent the hook from swinging during travel.

Mobile Crane: This is a broad category, and truck cranes are a primary type of mobile crane, designed to be easily transported to a job site.

Truck-Mounted Crane (TMC): This term is often used interchangeably and simply describes a crane mounted onto a commercial truck chassis.

Boom Truck: This is a very common term, particularly for truck-mounted cranes with a long, articulated or telescopic boom.

Specific Types of Truck-Mounted Cranes
These names usually refer to a particular design or function:

Boom Truck Crane (or Boom Truck): Refers to a crane that combines the mobility of a commercial truck with lifting capabilities. They often have an enclosed operator cab or an open, stand-up station.

Knuckle Boom Crane (or Loader Crane): This type has a hinged boom that resembles a human arm with joints (or "knuckles"), allowing it to fold up compactly. They are highly flexible for loading and unloading materials on the truck itself.

A specific brand name that is sometimes used generically for these is Hiab (a manufacturer of loader cranes).

Telescopic Crane (or Telescopic Boom Crane): This refers to the mechanism—the crane's boom uses hydraulic cylinders to extend and retract like a telescope. Most modern truck cranes use this type of boom.

All-Terrain Crane: While often larger, more specialized machines, these cranes are mounted on a carrier that can travel at highway speeds and maneuver on rough, unpaved terrain. They are essentially a highly advanced version of a mobile crane.

Rough Terrain Crane: These are designed only for off-road use, featuring four-wheel drive and oversized tires. They cannot typically travel on public roads like a standard truck crane.

The designation GSQS250-5 (or sometimes GSQS250-5) identifies the crane model, which is manufactured by a major Chinese machinery company, most notably XCMG (Xuzhou Construction Machinery Group).

Crane Type: Folding Mobile Crane (also known as a Knuckle Boom or Articulating Crane). This type is highly versatile, able to fold compactly for transport and perform complex lifting maneuvers in tight spaces.

Max. Lifting Capacity: 28 Tons (28,000 kg). This is the maximum weight the crane is rated to lift at its minimum working radius.

Crane Model Code: GSQZ is the industry designation for a knuckle boom crane, and 560 relates to the crane's power/lifting moment.

Max. Lifting Moment: Approximately 490 to 519 kN·m (Kilonewton meters), which is the primary measure of the crane's overall power (capacity * reach).

Max. Reach/Outreach: The maximum hydraulic working radius can extend to approximately 20.8 meters (for a model like the GSQZ560.8).

Slewing Angle: Typically 360° continuous rotation, allowing the operator to work in any direction.

Stabilizer Spread: Requires a large outrigger span (e.g., 8216 mm) to maintain stability when lifting heavy loads.

A crane mounted on a truck carrier provides the mobility for this type of crane. This crane has two parts: the carrier, often referred to as the Lower, and the lifting component which includes the boom, referred to as the Upper. These are mated together through a turntable, allowing the upper to swing from side to side. These modern hydraulic truck cranes are usually single-engine machines, with the same engine powering the undercarriage and the crane. The upper is usually powered via hydraulics run through the turntable from the pump mounted on the lower. In older model designs of hydraulic truck cranes, there were two engines. One in the lower pulled the crane down the road and ran a hydraulic pump for the outriggers and jacks. The one in the upper ran the upper through a hydraulic pump of its own. Many older operators favor the two-engine system due to leaking seals in the turntable of aging newer design cranes.

"HOWO Heavy Duty Folding Hydraulic Telescopic Knuckle Boom Truck With GSQS250-5 Crane" is a specialized heavy vehicle. The technical specifications are a combination of the Shacman 8x4 truck chassis and the GSQS250-5 knuckle boom crane

• Material Handling: Lifting and placing heavy construction materials such as steel beams, pre-cast concrete elements, large pipe sections, marble/stone blocks, or heavy machinery components.
• Formwork and Scaffolding: Hoisting large sections of formwork or scaffolding to elevated positions on construction sites.
• Bridge and Road Construction: Placing and positioning heavy culverts, bridge barriers, or road maintenance materials.
• Roofing/HVAC: Lifting and setting large, heavy rooftop units for heating, ventilation, and air conditioning (HVAC) systems.

• Self-Loading and Unloading: The truck can load its own cargo, transport it to the destination, and then unload it without relying on a separate crane or forklift at either end. This is a key advantage for remote or unstructured job sites.
• Container and Cargo Handling: Loading and unloading extremely heavy or oversized freight onto flatbeds or rail cars in ports, freight yards, or logistics centers.
• Machinery Relocation: Lifting and moving heavy industrial equipment and machinery within a plant or between sites.

• Power Grid: Lifting and setting large electrical transformers, distribution panels, and concrete power poles. The precision of the knuckle boom is useful for working around existing lines and infrastructure.
• Oil & Gas/Mining: Handling heavy valves, pipe bundles, and equipment in remote oil fields, refineries, or mining operations where space or ground conditions may be challenging.
• Telecommunications: Installing and maintaining large components on communication towers and masts.

The folding, or knuckle boom, design gives this crane a significant edge in specific scenarios:

• Working in Confined Spaces: The boom can fold and articulate, allowing it to reach over walls, fences, or other obstacles, or even feed material through windows and doorways in crowded urban environments.
• Below-Grade Lifting: The crane can articulate to lift items from below ground level (e.g., from an excavation pit or a basement) much easier than a traditional straight-boom crane.

For general cargo lifting and other special things like timber and brick by changing other equipment.
