Key Features and Applications
Knuckle Boom Folding Design
The SQZ84-4 utilizes a knuckle boom (folding) design, which allows the crane to be folded into a compact state when not in use. This significantly reduces the space occupied on the vehicle chassis, preserving the maximum possible area on the truck bed for cargo transportation.
Compact Installation Footprint
With a required installation space of only 900 mm, this crane is highly adaptable to a wide variety of light and medium-duty truck chassis. Its compact mounting requirements make it a versatile choice for urban utility vehicles and regional delivery trucks.
Precision Hydraulic System
Equipped with a hydraulic system featuring a rated pressure of 28 MPa and an oil flow of 25 L/min, the SQZ84-4 provides smooth and sensitive control during lifting and slewing maneuvers. This ensure the safe and accurate placement of loads in industrial or residential settings.
Lightweight Structural Build
Weighing only 1,400 kg, the crane is designed to minimize the impact on the vehicle’s total payload. This allows for a better balance between the weight of the lifting equipment and the actual cargo carrying capacity of the truck.
Versatile Small-Scale Applications
The SQZ84-4 is suitable for several sectors:
-
Municipal Maintenance: Handling street equipment, landscaping materials, and utility repairs.
-
Logistics: Quick loading and unloading of palletized goods in city centers.
-
Light Construction: Transporting and placing building materials on small project sites.

Dimensions and Operating Range
The SQZ84-4 features a 4-section folding boom that provides a flexible working radius for light-duty operations. The installation space is optimized at 900 mm to ensure it can be mounted behind the cab or at the rear of the truck without interfering with the main cargo area. Detailed working radius and lifting height capabilities are determined by the specific boom extension stages used during operation.
