This time，We specially invite Engineer Tan who is in charge of after-sales training.，Have a chat with everyone.，What the operator must know“Small things”。

Inspection before commencement，It's important！

According to the International Federation of Aerial Work Platform (IPAF) Compiled from the analysis of anonymous accident data《IPAF Global Security Report 2022》Medium analysis，The most common fall is from a platform.、Electric shock、Trapped、Overturn、Scenes where the mobile lifting platform is impacted by objects or vehicles。

△《IPAF Global Security Report 2022》

The main cause of such accidents.，Most of them are due to the fact that the operators and related staff do not have a good understanding of the construction environment.、Correct and complete inspection of the equipment prior to operation。

Engineer Tan stressed，Although the aerial work platform equipment is equipped with safety protection devices and protective measures,，But only when operated correctly、Only in the case of maintenance and use can it play a role.。So，Higher requirements for the quality of operators，It requires rich theoretical knowledge and practical skills.，So as to avoid accidents when working at heights.。

These places need to be checked before operation.

Engineer Tan said，Inspection before construction of aerial work platform，First of all, walk around the equipment.，Check whether the appearance of the equipment is normal，Whether there is a defect。There are three parts of the device to check：Structure、Hydraulic、Electrically controlled。

△Inspection around the machine

01

Inspection of structural parts

Structural part，Fence including inspection equipment、Boom、Chassis，Check whether there is serious rust at the above positions.、Weld cracking、The mechanical part is deformed；Whether the screw and pin roll are loose or fall off；Tire（Outrigger）Is there any serious scratch?；Whether there is any winding between hub reducers；Whether the drag chain and slide block are in good condition, etc.。

02

Inspection of hydraulic components

Hydraulic part，Attention should be paid to whether the hydraulic oil tank leaks.，Lack of hydraulic oil can damage hydraulic component。First，Check the level of the gauge located on the hydraulic tank and the color of the hydraulic oil。Secondly，Check the hydraulic oil tank、Pump set、Hydraulic lines、Valve block、Check whether there is hydraulic oil overflow around the cylinder and other parts.、Condition of dripping oil or residues。Whether the oil pipe of the pipeline is cracked，Whether there is falling off between the oil pipe and the metal joint。

03

Check the electric control circuit

Electric control part，It is necessary to check whether all lines on the solenoid valve are normal.，And ensure the reliable connection of the connector。At the same time，Check whether the battery voltage and electrolyte level are normal.，It is related to whether the electric emergency descent function can be started normally when the vehicle starts and encounters emergencies.。

△Check the electric control circuit

If it is a fuel equipment，It is also necessary to check the engine oil level and the antifreeze fluid level。Maintain proper engine oil level and antifreeze level，Essential for proper engine operation and extended service life。For battery-powered equipment，Pay special attention to the understanding and inspection of the battery and charger.。

In addition，The equipment shall be functionally tested before operation.。Include：Check the scissors、Check whether the emergency stop switch for getting on and off the arm-type product is normal；Check the pothole device of the scissor equipment、Emergency descent、Whether the manual release function is normal；Check the safety sensor of the arm product（Length、Angle、Weigh）Whether it operates normally；Check the scissors、Whether the function of the active emergency system of the arm-type product is normal。

In addition，The safety of working at height is also affected by the environment.，Uch as weather conditions、Site conditions、Whether there are dangerous goods around, etc.。So，Before working at height，A comprehensive assessment of the construction environment is required，Selection of safe construction methods，Ensure the life safety of construction personnel。

Construction operations shall be carried out from“Small things”Start

According to relevant statistics，2012-2022，On average, the construction scenarios that cause the most casualties each year are construction、Forestry/Tree care、Leasing activities、Transportation, etc，The location causing the most accidents is the construction site according to the construction location.、Roads and highways、Yard、Commercial premises、Public areas、Workshop、Office area。

Engineer Tan thinks so，If the correct steps are taken during use，All accidents can be avoided.。Safe Use of Aerial Work Equipment，There are no shortcuts.。He introduced，Pay attention to these things when working at height。

△Be alert to the danger of personal fall

01

Be alert to the danger of personal fall

During construction，Do not use the fork carriage or the boom assembly to enter or leave the platform。When entering or leaving the platform，Extra care should be taken，And make sure the boom is fully lowered。Extend the boom outward if necessary，Keep the platform as close to the ground as possibly，It is convenient for personnel to enter and exit the platform。When entering and exiting the platform，Should be facing the machine，With two hands and one foot.，Or two feet and one hand with the machine“Three-point contact”。

Before operating the machine，Make sure all doors are closed，And fixed in the correct position。During operation，Personnel on the platform must wear full-body safety belt，And tied to the seat belt anchorage with a rope。Only one rope may be attached to each seat belt anchorage。

Attention should be paid，Always work within platform，And keep two feet standing stably on the platform base plate.。Never use a ladder on a platform、 Case 、Steps、A board or similar object to shorten the distance.。

△Be alert to the danger of tipping

02

Be alert to the danger of tipping

Engineer Tan introduced，Mobile aerial work platform devices rely on the strength of the ground and the structure directly beneath them to support the weight in the platform、Any change in motion and load，And the associated reaction force。The location where the equipment touches the ground is often referred to as“Point of contact”，It can be a wheel.、Track、Stabilizer or leg。We need to focus on overloading of aerial work platforms.、Impact load or any sudden change or collapse of the ground on which the machine is operating。Include the following points:。

Do not easily change the weight of the equipment body and the distribution position of the weight.；Do not use the equipment in excess of its rated load；Not in the strong wind、Equipment used in severe weather such as rainstorm；Do not use force when the equipment is raised，Apply force, especially on that equipment or on the equipment, to objects other than the equipment。

In addition，Engineer Tan also emphasized that，Do not alter or damage any part of the machine that may affect safety and stability；Do not replace critical parts that may affect machine stability with parts of a different weight or size，Uch as a battery、Tires, etc。

△Be alert to the danger of collision

03

Be alert to the danger of collision

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 serious accidents occur.。So，Operators shall pay attention to the following points during operation。

When starting or operating the machine，Attention should be paid to the line of sight and the presence of blind spots.；Before releasing the brakes，The machine must be on a level surfaces，Or fixed。At the same time，Stay away from the path of the moving platform。

When rotating the turntable，Be careful of boom position and rotary tail flick。Also check the work area，In order to avoid obstacles or other possible dangers above the head of personnel.。

When the device is moved，Pay attention to the position of the extended platform（Scissors），Only in（Platform、Arm lever）When there are no people or obstacles in the lower area，To lower the platform.（Arm lever）。At the same time，According to the ground conditions、Crowding level、Slope、The position of the person and any other factors that may cause a collision，Limit the speed at which the equipment travels。
