The Self-Propelled Self-Leveling Wheeled 4WD Scissor Lift is designed for customers who need a high working height together with flexible driving performance and automatic chassis leveling.
The series provides maximum working heights of 13.8 m and 15.8 m, corresponding to the 14–16 m working height class.
Its most distinctive feature is the combination of:
Wheeled Chassis + Self-Propelled Travel + 2WD/4WD Switching + Automatic Chassis Leveling + 14–16 m Working Height
Instead of using a fixed two-wheel-drive or four-wheel-drive configuration, the machine allows operators to select the appropriate drive mode according to the operating condition.
At higher travel speeds, 2WD mode provides efficient driving performance. When stronger traction is required at low speeds, 4WD mode can be selected.
14–16 m Working Height
The machine is designed for elevated work in the 14–16 m height class.
Available maximum working heights are:
13.8 m
15.8 m
The SJPT1412E-T4 reaches a maximum working height of 15.8 m, making it suitable for applications requiring approximately 16 m of elevated access.
The different platform sizes and machine dimensions allow customers to select the appropriate model according to their project requirements.
Self-Leveling Wheeled Chassis
The automatic chassis leveling system is one of the key features of this scissor lift.
Instead of relying only on a fixed chassis position, the machine can automatically adjust the chassis leveling system to help maintain a suitable level condition.
This feature provides:
Automatic leveling
Easier machine setup
Improved operational convenience
Additional stability support
Better adaptability to suitable working surfaces
The leveling function should always be used within the manufacturer's specified operating conditions and limits.
Automatic Chassis Leveling
The machine uses an integrated automatic self-leveling system.
When the machine is positioned on a suitable working surface, the leveling system can automatically adjust the chassis according to the machine's control logic.
This eliminates the need for operators to manually perform complex leveling adjustments.
For elevated operations, maintaining an appropriate machine level is particularly important.
The automatic leveling function therefore provides a more convenient solution for applications where ground conditions require chassis adjustment.
2WD / 4WD Freely Switchable
The 2WD/4WD switchable drive system is another major advantage of this model.
The machine can operate in two different drive modes:
2WD Mode
The two-wheel-drive mode is designed for:
Higher travel efficiency
Faster repositioning
Lower drive energy demand
Suitable high-speed travel
The maximum stowed travel speed is 4.5 km/h.
4WD Mode
Four-wheel drive is designed for:
Stronger traction
Higher low-speed driving force
Improved driving capability
Suitable demanding travel conditions
This allows the operator to choose the appropriate drive mode according to the working environment.
High-Speed 2WD + Low-Speed 4WD
The drive strategy can be summarized as:
High-Speed Travel → 2WD
Low-Speed / High-Traction Operation → 4WD
This configuration combines the efficiency advantages of two-wheel drive with the traction advantages of four-wheel drive.
Compared with a machine permanently configured for four-wheel drive, the switchable system provides greater flexibility.
Operators can use efficient 2WD operation during normal repositioning and select 4WD when additional traction is required.
Self-Propelled Wheeled Operation
The machine is a Self-Propelled Wheeled Scissor Lift, allowing operators to drive and reposition the platform using its integrated travel system.
There is no need for manual pushing during normal repositioning.
This is particularly useful for:
Construction sites
Industrial facilities
Large buildings
Maintenance projects
Installation projects
The self-propelled wheeled configuration allows the machine to move efficiently between suitable work areas.
AC Motor Drive
The machine uses an AC motor drive system.
The AC motor provides:
High efficiency

Long service life
Responsive driving performance
Reliable operation
The AC drive system works with the 2WD/4WD switching system to provide flexible driving performance.
450 kg Rated Load Capacity
Both models provide a rated load capacity of:
450 kg
This allows the platform to accommodate operators, tools and approved materials within the specified load limit.
When calculating platform load, the total combined weight of personnel, tools and materials should be considered.
Large Working Platform
The machine provides practical platform dimensions for elevated work.
Available platform sizes include:
2.27 × 1.13 m
and
2.73 × 1.13 m
The larger platform provides additional working space for operators, tools and approved materials.
Extendable Working Platform
The platform includes a one-way extension.
Available platform extensions are:
0.9 m
1.1 m
The extension provides additional horizontal access to elevated work areas.
This can help operators reach areas outside the main platform without constantly repositioning the machine.
Intelligent Human-Machine Interaction
The machine features a display-based human-machine interaction system.
Available functions include:
Parameter setting
Fault diagnosis
Parameter reading
Parameter writing
System monitoring
The display provides operators with convenient access to machine operating information.
Maintenance personnel can also use the system to support equipment inspection and troubleshooting.
Fault Diagnosis System
The integrated fault diagnosis system helps identify potential machine problems.
It can support:
Equipment status monitoring
Fault identification

Emergency Lowering
The emergency lowering system provides an alternative method for lowering the platform if normal operation is unavailable.
Platform Self-Locking Gate
The self-locking platform gate helps reduce the risk of accidental opening during elevated work.
Fault Diagnosis
The fault diagnosis system supports machine monitoring and troubleshooting.
Convenient Maintenance
The machine uses an optimized design with integrated side pull-out trays, making routine inspection and maintenance more convenient.
