Product Introduction
The GTBZ26S is a large-scale intelligent articulated boom aerial work platform positioned at the high end. It is not merely a simple height extension, but a comprehensive upgrade in terms of operation range, obstagle-crossing ability, intelligent control, safety level and chassis performance. It can handle extreme working conditions that are difficult for other equipment to reach, providing customers with efficient, safe and reliable ultimate solutions for high-altitude operations. It is an indispensable key equipment in large-scale engineering projects.
Product Advantage
1.Ability in Fast Access to the Construction Area
The boom driven by a single cylinder and the synchronously amplitude-varying and lifted stand column enhance the operating speed, and realize the fast access to the construction area, which will improve the construction efficiency.
2.Better Adaptability to Poor Construction Enviroment
The application of a lubrication-free shaft sleeve and slider relieves the friction between each hinge point for connection and inter-arm slider, thus resulting in better adaptability to welding and dusty enviromeent.
3.Advanced power system integration control
Electronic-controlled engine is adopted as the dynamical system, oil pressure, water temperature, rotating speed, sensor etc. are integrated by engine and controlled through ECU, which is safe and reliable. Meanwhile, there is a fault diagnosis interface as supporting for convenient of fault diagnosis and maintenance.

Product Operate Guide
1. Power selection: Choose pure electric (indoor silent) or diesel (outdoor range) mode on the panel according to the working conditions
2. Boom operation: The three sections of the boom are smoothly controlled by the proportional control handle, and the electro-hydraulic proportional micro-motion mode is preferred for precise positioning
3. Chassis operation: Before operation, extend the horizontal outriggers until the floating indicator light goes out. For complex road surfaces, it is recommended to activate the four-wheel drive mode
4. Safety Monitoring: Pay real-time attention to the platform load display instrument (overloading is strictly prohibited) and the tilt alarm device
5. Emergency Procedure: In case of sudden abnormality, immediately press the emergency stop button and implement emergency descent through the manual pump
FAQ
1.What type of power system is it?
A: It adopts hybrid power (diesel + AC motor) and supports switching between pure electric silent mode and diesel power mode.
2.What are the steering modes?
A: Equipped with front-wheel steering, four-wheel steering and crab mode, it can adapt to different working conditions.
3.How to achieve obstacle crossing work?
A: By using the "flying arm" function of the three-section arm in combination with 360° continuous rotation, it can flexibly overcome obstacles such as pipes and walls.
4.What are the key safety devices?
A: Equipped with multiple protections
• Dual-redundant control system
• Tilt alarm + automatic limit
• Automatic overload limit
Emergency manual descent device
• Safety relief valve for hydraulic system
5.What should be done in case of sudden power outage or power failure?
A: Activate the emergency mode immediately
Press the emergency stop button
2. Rotate the manual pump to ensure the safe descent of the platform
6.Which items need to be checked on a daily basis?
A: Check before daily work
• Check for cracks or deformations in structural components
• Hydraulic oil level and pipeline leakage
• Battery power/diesel fuel level
• Safety device function test
