18m & 20m Dual Power Spider Aerial Work Platform
Dual-Power Spider Lift for Flexible Work at Height
The 18m and 20m Dual Power Spider Aerial Work Platforms are compact tracked aerial lifts designed for high-level construction, maintenance, installation and other elevated work applications.
The range includes two models:
THZ-18T – Maximum working height: 18m
THZ-20T – Maximum working height: 20m
Both models have a 230kg rated load capacity and an ultra-narrow 0.88m overall width.
The biggest feature of this series is its dual power system, which combines a KUBOTA D902-E3B diesel engine and an electric power system. The operator can switch between diesel and electric power according to the working environment and operating requirements.
This makes the dual power spider lift more flexible than a single-power aerial platform. It can be used in suitable outdoor environments while also providing an electric operating option for locations where reduced emissions and lower operating noise are important.
Combined with non-marking rubber crawler tracks, automatic outrigger leveling, wireless remote control, proportional hydraulic control and a telescopic aluminum boom, the machine provides a flexible solution for elevated work in confined and demanding environments.
Key Features
1. Dual Power: Diesel + Electric
The most important feature of the THZ-18T and THZ-20T is the dual power system.
The machine is equipped with:
KUBOTA D902-E3B diesel engine
Electric power system
Dual-power operating capability
Flexible power switching
The operator can select the appropriate power source according to the application.
Diesel Power
Diesel power is suitable for many outdoor applications where longer-duration operation and independent power supply are required.
It provides a practical power solution for construction sites, outdoor maintenance and other suitable working environments.
Electric Power
Electric operation can be used in suitable environments where lower operating emissions and reduced noise are preferred.
This can be particularly useful for indoor or semi-indoor maintenance projects, subject to site ventilation, floor conditions and other operating requirements.
Flexible Power Selection
The dual-power configuration allows users to adapt the machine to different job sites instead of relying on only one power source.
This provides greater operational flexibility for contractors, rental companies and equipment users who work across different environments.
2. 18m and 20m Working Height Options
Two working height options are available.
THZ-18T – 18m Spider Lift
The THZ-18T provides a maximum working height of 18m.
It is suitable for customers whose projects require approximately 18m of elevated access.
THZ-20T – 20m Spider Lift
The THZ-20T provides a maximum working height of 20m.
The additional working height makes it suitable for taller buildings, structures, trees and other applications requiring greater vertical access.
Both models provide a 230kg rated load capacity.
3. Ultra-Narrow 0.88m Body
The spider aerial work platform has an overall width of only 0.88m.
The ultra-narrow design allows the machine to pass through relatively restricted access areas.
It can be considered for projects involving:
Narrow entrances
Gates
Corridors
Building passages
Restricted construction areas
Indoor maintenance areas
The compact body is one of the major advantages of a spider lift compared with larger conventional aerial work platforms.
4. Non-Marking Rubber Crawler Tracks
The machine uses non-marking rubber crawler tracks.
The tracked chassis provides good mobility on suitable surfaces and can help the machine move through uneven outdoor working areas.
The rubber track design also helps reduce surface marking on suitable finished floors.
Before indoor operation, users should confirm that the floor structure, surface condition and floor load capacity are suitable for the machine.
5. Extendable Crawler Tracks
The crawler tracks can be extended and retracted from both sides.
The narrow configuration helps the spider lift pass through restricted access areas.
When traveling or positioning on suitable ground, the tracks can be extended to provide a wider and more stable configuration.
This provides a combination of:
Narrow Access + Flexible Mobility + Improved Stability
6. Automatic Outrigger Leveling
The machine is equipped with an automatic outrigger leveling system.
The system helps the operator establish a stable working position more conveniently.
Automatic leveling can reduce setup complexity and improve operating efficiency when the machine is deployed on suitable ground conditions.
The machine should always be operated according to its specified leveling, slope and ground-condition requirements.
7. Wireless Remote Control
The THZ-18T and THZ-20T are operated using a wireless remote control system.
Wireless control allows the operator to maintain a suitable position while controlling the machine.
Depending on the operating configuration, remote control provides flexible management of:
Machine travel
Boom movement
Platform positioning
Outrigger operation
Other machine functions
The remote control design is particularly useful when the operator needs a clear view of the machine and surrounding working area.
8. Precision Proportional Hydraulic System
The machine uses a precision proportional hydraulic control system.
The proportional hydraulic system provides smoother machine movements and better speed control.
This is important when performing precise elevated work near:
Building facades
Glass panels
Trees
Lighting systems
Industrial structures
Construction components
The good micro-movement performance allows the operator to position the platform more accurately.
9. High-Strength Telescopic Aluminum Boom
The spider lift is equipped with a single-stage telescopic aluminum boom.
The high-strength boom provides good structural rigidity while maintaining a compact machine configuration.
The telescopic structure allows the platform to reach high working positions while providing flexible positioning.
The boom system is designed to provide smooth and stable movement during elevated operation.
10. ±355° Turntable Rotation
The turntable provides ±355° non-continuous rotation.
This provides a wide operating range around the machine.
The operator can reposition the platform across a large working area without constantly moving the entire crawler chassis.
11. ±90° Platform Rotation
The working platform provides ±90° rotation.
Platform rotation allows the operator to adjust the working position according to the specific work area.
Combined with turntable rotation and boom movement, the system provides flexible positioning around buildings and other structures.
12. Dual-Screen Human-Machine Interface
The machine is equipped with a dual-screen human-machine interface.
The system supports functions such as:
Parameter setting
Fault diagnosis
Parameter reading and writing
System monitoring
Operating information display
This helps operators and maintenance personnel monitor machine status and troubleshoot potential problems more efficiently.
Main Equipment Configuration
The standard configuration includes:
Dual power system
KUBOTA D902-E3B diesel engine
