I wonder if you know.，Our productsWhat are the safety designs?？Product before launch，It needs to be doneWhich onesRigorous safety testing？Future High Machine ProductsWhat is the direction of development?？

Below ，We will answer for you one by one.。

Safety certification，Product core competitionForce

A qualified equipment is not just a simple combination of various parts.，Pecially as aerial work equipment for carrying people，It has extremely high requirements for safety.。So，Products tested and evaluated to various safety certification standards，It will be more secure in use.。

▲Zoomlion Intelligent High MachineZT68JYesCECertificate of authentication

Equipment sold by Zoomlion Intelligent High Machine，Most of them passedEuropean Union“CESafety certification”，It's safe、Reliable、Compliant products。It is worth mentioning that，Products in Load Sensor System、Position Control、Torque sensor system、Leveling system、Prevent walking beyond the inclination limit、Travel speed limit、Interlock of control position, etc.17 important safety function test items，All in line《BS EN 280》Performance Level Requirements for Aerial Work Platform Service Standards，Excellent quality and good safety performance。

The innovation and development of Zoomlion Intelligent High Machine in safety protection technology has indeed attracted much attention.，In addition to being certified to international safety standards,，Its many security technologies also lead the development of the whole industry.。

Independent research and development，Safety-oriented“Black technology”

According to industry experts，Although working at height with aerial work equipment is usually very safe，But when the danger occurs,，It can still cause serious accidents.。

Zoomlion Intelligent High Machine has been adhering to“Technology is the root，Product-based”The principle of，By meeting the international standards of the industry and the needs of actual working conditions，DevelopedUnique safety features such as anti-extrusion and anti-collision，Provide users with safer and more reliable equipment。

▲Boom Aerial Work Platform

For example，Boom type aerial work equipment requires special attention to safety issues when moving。Due to the large size of such products,、Limited line of sight，In addition, complex operations are required.，Therefore, accidents are prone to occur in the process of moving.。Pecially during backward movement or reversing.，If the operator is not aware of a large rear obstruction，It is easy to cause great extrusion injury to the personnel in the working platform.，Even casualties occur.。

▲Zoomlion intelligent high-speed machine swing-arm type anti-extrusion system

However，Most of the existing protection systems for the safety of working platforms in the industry have insufficient protection scope.、It is easy to trigger the alarm by mistake.，The safety of operators cannot be effectively guaranteed.。In order to solve this problem, Zoomlion Intelligent High Machine，Innovative designSwing arm type anti-extrusion system。The system adopts a swing arm type protective structure.，It can give consideration to both protection space and detection stability，Avoid false triggering，And provide an alarm、Limiting and other functions。At the same time，The system also has a separate pressure bar with progressive zoning safety control technology.，Gives the operator a larger safety avoidance space.，Ffectively ensure the personal safety of the operator。

Another example，Platform anti-collision function，In the early stage, the collision detection of mechanical structure was mainly used.，The effect is not ideal in practical application.。Innovative research and development of Zoomlion intelligent high machine“Anti-collision Technology of Boom Aerial Work Platform”，Which adopts a non-contact obstacle detection mode based on ultrasonic ranging.，Relative velocity between platform and obstacle、The distance is monitored and the corresponding control strategy is adopted for the equipment through the central processing unit.，Avoid platform collision。

▲Anti-collision Technology of Zoomlion Intelligent High-boom Aerial Work Platform

Compare with that traditional mechanical anti-collision technology，The anti-collision technology has that advantage that the detection range is large,（The space coverage rate reaches 92.5%）、The detection distance is long（The longest detection distance can reach 2500mm）、And that reliability is high（The sensor is mounted flush、Contactless detection，Durable），The safety of the operating platform is effectively guaranteed in the work engineering.。

Top priority，Safety test during R & D

It is well known，Zoomlion Intelligent High Machinery has industry-leading digital intelligent debugging system and key test equipment.，Various technical research tests can be carried out.、Safety-related tests such as product type tests and all product certification tests。

It is reported that，In the design stage, all products of Zoomlion Intelligent High Machine need to pass through the whole machine.Stability test、Structural performance testAndReliability testStrict examination of safety-related tests.。Among，Overall stability test includes:：The whole machine tilts forward、Backward Static Stability Test and Potholes、Curb stone、Walk on the ramp、Luffing emergency stop、Dynamic stability test of the whole machine such as dropping，The total is up toMore than 120 test items in 28 categories。

▲Product safety testing

In the aspect of structural performance test，Zoomlion Intelligent High Machine has carried out the following activities:：Material composition and mechanical properties、Structural stress、Structural fatigue、Ultimate bearing capacity、Impact damage, etcMore than 10 structural safety related testsProject，To ensure that the product structure does not fail during use.，With sufficient safety margin。

In terms of product reliability test，Hydraulic valves are developed、Pump、Electric machinery、Wire rope fatigue、Weldment fatigue、Electro-hydraulic joint test, etc.More than 140 items in 50 categoriesParts、Component、System、Complete machine reliability test，Covering Europe、America、 Canada 、More than 10 standards in Australia and other regionsAll test items required，Ensure product parts、System、The reliability of the whole machine has been tested comprehensively.。

▲Product safety testing

So，In order to ensure product quality and safety，It is essential to test the equipment repeatedly during the development process.。These tests and verifications can ensure that Zoomlion's products meet standard requirements and meet customer needs.，And has excellent safety and reliability in use.。

Future development direction：Intelligent、Unmanned

Nowadays，The complexity and danger of aerial work are attracting more and more attention.，After all, working at heights.，Operators need to face many dangerous environments and dangerous working conditions.。It not only includes the working environment with limited space formed by steel frame, etc.、Potholed walking environment，And spaces filled with dust，More movement to fit the facade，Handling and installation of fragile articles such as glass，As well as the traversal of a large range of facades for a long time.。
