GTBZ39 & GTBZ44Z Self Propelled Aerial Work Platform

High Safety of Body Structure
Patented Weighting System: can accurately weight what on the platform with automatic division of various load levels; Precise Weighting Ability in all locations of the platform for objects or humans; Automatic power cut-off and alarm with light and sound when the platform is over-loaded.

Patented Socket Tow-Chain System: avoid serious disorder and rupture of the cables and oil-pipes, which is caused by over-bending of boom and cantilever tow-chain.

Unique Lift Arm Design and Structure: The boom is made of high-strength steel plate, which guarantee our products having sufficient strength , resistance ability to deformation. Through the methods of finite element analysis and dynamic simulation, the boom can realize lightweight design.

Travelling System
Axis Oscillating: driven by hydro-cylinder , the wheel axis oscillating can fully ensure stability of the whole machine when working.

Four-Wheel-Drive and Solid Tires: four turning modes including front-wheel, rear-wheel, front & rear turning and slanting drive, powerful gradeability.

Electrical Controlling System

Automatic Range Restrictor: safety alarm, auto speed-limiting and range restriction function which is controlled by intelligent system.

Double Sensors and Dual-poop Protecting Circuit: to guarantee high reliability and durability of the whole electrical controlling system.

Advanced CAN-BUS Controlling Mode: simple circuit,, easy maintenance and excellent reliability.

High-Quantity Steel Connector of Aerial Craft: the protection level reach IP65.

Emergency Power Unit: ensures retracting in case of engine failure.

Humanizing joystick: makes operators feel convenient and comfortable.
