As we all know, the elevating platform truck is a high-altitude operation, so safety is particularly important, so how can we avoid the risk of falling?
- There are many reasons for the falling accident of the lifting platform truck, which can be summarized as follows:
(1) The braking torque of the brake of the drive device is not enough, and the safety factor is too small;
(2) The problem of a single drive and double (multiple) drives;
(3) The reliability of the anti-fall safety device is poor;
(4) Violating the deduction regulations, not in accordance with the provisions of the product manual, overload operation;
(5) There is no leaning wheel on the back of the meshing place between the driving pinion and the rack, or there is no locking plate on the eccentric shaft of the leaning wheel;
(6) No balance weight is set;
(7) Other occasional reasons;
- Analysis and comparison of the safety device of the driving device
The brake is a device for parking the floor. There are roughly two types of brakes currently used: one is the standard JWZ200 block brake with a braking torque of 160N m, which is a mature product. Its disadvantage is that the size is large. , the brake is easy to wear and tear, such as improper maintenance and maintenance, it is easy to fail.
This kind of brake is mostly used on the lifting platform produced in the 1980s, and it is rarely used now and is gradually being phased out;
The other is developed in the late 1980s with reference to the imported prototype of ALIMAK, which is a disc friction brake connected with the drive motor. It is a pull-type friction brake connected to the drive motor.
This brake is characterized by compact structure, small volume, and easy adjustment of the gap between the brake pads. At present, elevating platform trucks all use this kind of brake.
Any technical equipment in the car requires repair and maintenance. The scope and frequency of maintenance are determined according to the working conditions of the Isuzu aerial work vehicle. According to different maintenance rules and maintenance intervals, it is divided into three maintenance categories.
The requirements for maintenance preparatory work and maintaining operational reliability are discussed in the maintenance manual. Inspection and maintenance require sophisticated technology.
These can not be obtained in the manual, to carry out this work, it is recommended to send someone to the gallop repair station for training. In order to maintain good maintenance, it is necessary to have skilled experience, technical information of the factory, workshop equipment and maintenance tools.
A sign reminding maintenance work is attached by the maintenance station to the door of the driver’s seat. Any repairs and maintenance will depend on the working conditions of the aerial work vehicle.
Put lubricating oil, fuel oil, cooling water in a basin or similar container, do not put it on the ground (environmental pollution), do not start the engine for a long time, and pay attention to safety rules when operating in the car.
Regarding lubrication, the maximum pressure with a grease gun does not exceed 400 bar. Grease guns have no safety features and can damage bearings, ball joints, oil seals, etc. Pay attention before refueling.
Clean the lubricating oil nipple and pay attention to cleaning it before unscrewing the oil drain plug. Special equipment for lubrication, in accordance with the manufacturer’s instructions.
The required special tools, such as a set of universal tools and torque wrenches, can be supplied by the workshop spare parts department.
All repair stations are stocked with original parts for repairs and maintenance, ensuring a prompt supply of original parts to users around the world and in places.
In the central equipment warehouse, more than 200,000 different accessories are stored. There are more accessories for the older model elevating platform truck.
The elevating platform truck maintains optimum functionality and reliability of the aerial lift truck by using original spare parts that can withstand inspections of the highest quality.
In particular, the development, manufacture, or selection of each component is suitable for the elevating platform truck. Therefore, only original accessories should be used.
