PJZ Balancer: Fixed-Mount Industrial Lifting Solution
Product Introduction
The PJZ series balancer is a lightweight material handling device designed for small-to-medium multi-variety production environments. It is ideal for loading/unloading and assembly line integration, offering greater accuracy and directness than cranes and electric hoists, while being simpler and more flexible than manipulators. The series includes 8 models ranging from PJZ010 (100kg) to PJZ1.0 (1000kg), with Rmax=2500~3200mm, lifting height of 2000~2600mm, and 345-degree rotation.
The PJZ series balancer features a well-engineered structure, safe and easy operation, excellent performance, and a long service life. Utilizing a four-bar linkage and screw lifting principle, the load floats freely in three-dimensional space and can be moved to any position with a gentle push, making it ideal for loading, unloading, and assembly line operations in small-to-medium multi-variety production settings.

Product Features
Four-bar linkage for intuitive positioning: The four-bar parallelogram scaling mechanism allows the load to float in three-dimensional space, reaching any position with simple manual push or pull. Positioning is accurate, intuitive, and easy to control.
More precise than cranes/hoists, more flexible than manipulators: The PJZ balancer offers positioning accuracy and flexibility between traditional lifting equipment and manipulators, combining the strengths of both — ideal for small-to-medium multi-variety production scenarios.
Full model range covering 100~1000kg: 8 models span the entire 100~1000kg range with Rmax=2500~3200mm for extensive coverage. The PJZ1.0 offers a load capacity of 1000kg and a lifting height of 2600mm.
Well-engineered, safe, and easy to operate: The rational structural design delivers excellent performance, safe and simple operation, and a long service life. The screw mechanism features self-locking, and overload protection ensures safety.
Working Principle
The PJZ series balancer operates on the four-bar parallelogram scaling principle combined with screw-driven lifting. The main structure consists of a column, four-bar linkage arm, screw lifter, and hook block. The four-bar linkage forms a deformable parallelogram through pivoted connections — as the load moves horizontally, the parallelogram scales to keep the hook traveling along a vertical line. The screw lifter uses a motor-driven leadscrew to raise and lower the nut, providing smooth transmission with self-locking capability.
During operation, the operator grips the handle and gently pushes or pulls to move the load horizontally; the column rotates 345 degrees to cover the working area. Buttons control the screw lifter's forward/reverse rotation for lifting and lowering. The overload protector automatically cuts off power when the load exceeds limits, and the limit protection device stops operation automatically at extreme positions.
Structural Composition
Comprising the following core components:
Column and slewing mechanism: A steel column fixed to the base, H=2785~3940mm. A top slewing bearing supports 345-degree rotation.
Four-bar linkage arm: Parallelogram four-bar structure with Rmax=2500~3200mm and level luffing range of 1730~2200mm.
Screw lifter: Motor-driven leadscrew and nut transmission, ZDY series motor power 0.75~3kW, lifting speed 2.54~6.14m/min.
Safety protection devices: Overload protector and limit switches for extreme positions.
Electrical control system: Handle button inching control, 380V three-phase power supply.

FAQ
Q: What is the difference between the PJZ Balancer and the PJ Balancer?
The PJZ and PJ series share the same core mechanism (four-bar linkage + screw lift), with the main difference being the naming convention. PJZ models use the "PJZ" prefix (e.g., PJZ010 = 100kg), while PJ models use the "PJ" prefix (e.g., PJ005 = 50kg). The PJZ series covers 100–1000kg, while the PJ series covers 50–600kg. There are slight differences in dimensions and parameters between the two, so the choice depends on your specific installation conditions.
Q: What does "1.0" mean in the PJZ1.0 model?
In the PJZ1.0 model, "1.0" represents a load capacity of 1000kg (1 ton). Similarly, PJZ010 = 100kg (0.1t), PJZ020 = 200kg (0.2t). The number in the model directly corresponds to the load capacity (in hundreds of kg or tons).
Q: What is the difference between the ZDY121-4 and ZD131-4 motors used in PJZ Balancers?
The ZDY121-4 has a power of 0.75kW (for PJZ010), the ZDY122-4 has 1.5kW (for PJZ020), the ZDY123-4 has 2.2kW (for PJZ030/040), and the ZD131-4 has 3kW (for PJZ050 to PJZ1.0). The higher the load capacity, the greater the motor power to provide sufficient lifting force.
Q: What are the installation requirements for a PJZ Balancer?
A level, hardened floor is required, with the base secured using anchor bolts. Power supply is 380V three-phase, and a Residual Current Device (RCD) is required. Smaller models (PJZ010–040) require a minimum clear height of 3m, while larger models (PJZ050–1.0) require a minimum clear height of 4.2m. A site survey by a technician is recommended before installation.
Q: What type of production environment is the PJZ Balancer best suited for?
The PJZ is particularly well-suited for small-to-medium-sized, multi-variety production environments—thanks to its flexible operation and intuitive positioning, it offers greater precision than a crane and is simpler than a manipulator, allowing quick changeover to different workpiece handling tasks without complex programming. Its advantages are especially prominent in flexible production lines with frequent product changeovers.
