Causes and maintenance of the failure of the up and down buttons of the crane remote

1. Personnel operation

When some crane operators use the crane, especially when installing molds (title: Mother of Industry), they are accustomed to operating the remote control with both hands in order to more accurately install the mold in the injection molding machine. Some operators prefer to hold the remote control with their left hand and press the buttons with their thumbs, while others press the buttons with their right hands. Because the remote control button is very light, it is often mis-operated.

2. Crane line problem

When the crane is used for a long time and frequently (frequency), some lines and joints have obvious aging phenomenon, especially if the line is loose, or the crane directly fails, or the crane cannot be used. The single beam crane has two operation modes: ground and air. There are two types of ground operation: wired handle operation and remote control handle operation; aerial operation refers to operation in the driver's cab. The driver’s cab has two types: open and closed. It can be divided into two types for installation on the left or right according to the actual situation. There are two types of entry directions: side and end to meet the needs of users. Since the connectors are frequently depleted or the rated voltage is less than 1/10, the connectors cannot be combined, which may also cause the crane to fail up and down. Before the crane broke down, we pressed the remote control key with our hands. When we can hear the sound absorption of the remote control from top to bottom, the connector is normal. If there is no sound absorption, there may be a problem with the connector or cable.

3. The problem of electric hoist

When the electric hoist is in use, the abnormal noise, overheating or oil leakage of the reduction shaft caused by the lack of oil in the reduction shaft box should be stopped immediately to check whether the motor is running; the offset of the coupling, the wire rope (from the steel wire, the rope The main problem is the guide of the core and grease composition and the aging of the elevator brake disc. The single beam crane has two operation modes: ground and air. There are two types of ground operation: wired handle operation and remote control handle operation; aerial operation refers to operation in the driver's cab. The driver’s cab has two types: open and closed. It can be divided into two types for installation on the left or right according to the actual situation. There are two types of entry directions: side and end to meet the needs of users. The upper and lower limit nut or the spring on the limit rod is severely worn (a basic type of component failure), resulting in reduced spring force and lifting problems.

In view of the above three points:

1. The problem of personnel operation Our production (Produce) operators must be trained before using the crane remote control (function: knowledge transfer, skill transfer, standard transfer), and the licensee can operate it.

2. Professional electricians regularly inspect the organization for crane line problems, or find crane manufacturers for training (function: knowledge transfer, skill transfer, standard transfer). The single beam crane has two operation modes: ground and air. There are two types of ground operation: wired handle operation and remote control handle operation; aerial operation refers to operation in the driver's cab. The driver’s cab has two types: open and closed. It can be divided into two types for installation on the left or right according to the actual situation. There are two types of entry directions: side and end to meet the needs of users.

3. For electric hoist problems, we need to contact the manufacturer for confirmation, and replace the parts that need to be replaced in time to achieve zero failure.
