GTJZ Fully Automatic Self-Propelled Lift High-Altitude Work Platform
Product Introduction
The GTJZ fully automatic high-altitude platform, also known as a self-propelled lift, lift truck, aerial work platform, or lifting platform, is a rechargeable, self-propelled scissor lift. Its compact, mini design—with a platform size of just 1.29 × 0.7 m and a width of only 0.76 m—allows it to easily pass through a standard single door, making it purpose-built for aerial work in confined spaces. The operator stands on the platform and controls the entire process—driving, steering, and lifting—via the handle controller, with no ground assistance required. A single operator can handle the job independently, significantly boosting efficiency and reducing labor costs.
The GTJZ series is available in two models: GTJZD03 (maximum platform height 3 m, working height 5 m) and GTJZD06 (maximum platform height 6 m, working height 6 m). With a safe load capacity of 240 kg and a dead weight of 860–890 kg, it can carry two people plus tools simultaneously. Built-in safety features include overload detection, tilt alarm, and low-battery protection, making it widely suitable for aerial maintenance work in building decoration, factory maintenance, hotels and venues, and municipal facilities.

Working Principle
The GTJZ fully automatic high-altitude platform is powered by a battery pack (2×12V/60Ah), which drives a DC motor to operate a hydraulic pump, providing lifting power for the scissor arm system. The travel system uses two DC drive motors (2×24VDC/0.5kw) to independently drive the left and right drive wheels, while the front wheels are swivel casters, enabling forward, reverse, and zero-radius turning. When the operator issues travel or lifting commands via the control grip, the PLC controller coordinates the motor speed controllers and hydraulic valve group to execute the actions.
The scissor arms are welded from high-strength alloy steel, with multiple sets of scissor units connected by hinges for synchronized telescoping. Platform lowering is achieved through dead weight and hydraulic oil return, with the hydraulic valve group incorporating throttling speed control and locking functions. Overload protection cuts off lifting power when the load exceeds 110% of the rated capacity. Tilt protection triggers an audible and visual alarm and shuts down the machine when the chassis tilts more than 2° laterally or 3° longitudinally. When the battery is low, lifting is restricted while residual power is reserved for traveling to the charging station.

Selection Guide
The GTJZ series offers two base models: GTJZD03 (max platform height 3m, working height 5m) and GTJZD06 (max platform height 6m, working height 6m). Both have a safe load capacity of 240kg and identical platform dimensions of 1.29×0.7m. Model selection is primarily based on working height requirements — choose the GTJZD03 for maintenance work below 3m, or the GTJZD06 for the 4~6m range. Both models share similar width and weight (890kg vs 860kg), offering the same passage adaptability. Optional upgrades include a lithium battery package (reducing charging time to 2~3 hours) and an extension platform locking mechanism.
Operation Instructions
Pre-Operation Checks: Verify the battery is sufficiently charged (charge indicator no lower than 20%), the hydraulic oil level is normal, and all fasteners are secure. Check that the platform guardrails and drop-gate latches are intact, and the ground load-bearing capacity is no less than 1.5t/m².
Travel Operation: Release the parking brake, push the grip forward/backward for forward/reverse travel, and rotate left/right for steering. Travel speed is 4.0km/h with the platform fully lowered, automatically limited to 0.5~0.8km/h when elevated. The compact chassis enables zero-radius turning in narrow corridors (inside turning radius 0.3m).
Lifting Operation: Press and hold the up button until the desired height is reached; release to stop. For lowering, press and hold the down button, with a controllable speed of 4~6m/min. The platform allows a maximum tilt angle of 2° (lateral) / 3° (longitudinal); exceeding this triggers an automatic alarm and shutdown.
Safety Notes: Never exceed the rated load (safe load capacity 240kg including personnel and tools). Never drive or turn while the platform is elevated. The platform must be fully lowered and the power turned off before leaving the platform. Fault codes are automatically displayed on the controller panel — refer to the operation manual for quick fault identification.

FAQ
Q: Can the GTJZ series be used indoors? What is the minimum door width it can pass through?
A: Yes. The GTJZ series has an overall width of only 0.76m, allowing it to easily pass through a standard single door (typically 0.8~0.9m wide). With the guardrails folded, the height is only 1.625~1.67m, enabling transport via passenger elevator to upper floors. The indoor floor must be level and hard (concrete/tile/wood flooring are all suitable), with a load-bearing capacity of no less than 1.5t/m² and a slope not exceeding 3° (longitudinal) / 2° (lateral).
Q: What are the main differences between the GTJZD03 and GTJZD06? How do I choose?
A: Both models share identical platform dimensions, load capacity, and width (1.29×0.7m / 240kg / 0.76m wide). The core difference lies in the platform height: the GTJZD03 offers a maximum platform height of 3m (working height 5m), while the GTJZD06 reaches a maximum platform height of 6m (working height 6m). Selection guide: For indoor ceiling maintenance (typically 2.5~4m), the 03 model is sufficient; for factory equipment and piping installation (4~6m), opt for the 06 model.
