Wire rope hoist cases studies: 3 typical wire rope hoist installation and commissioning problems and solutions for your reference. Dongqi wire rope hoist improve your material handling efficiency and ensure your safety. Types of wire rope hoist are offered, i.e., electric hoists, low headroom hoist, variable speed wire rope hoist, explosion proof hoists, etc.
Wire rope hoist for your reference
With the installation manual of electric wire rope hoist, the client successfully finished the work and next is the wire connection. According to wire diagram, all the connections are seems no problem, client feedback that electric hoist traveling is normal, but the lifting motor has no action;
Dongqi Hoist and Crane technically advises to check the wire rope connections and test each point of rope wires to make sure it is connected with power, unfortunately, this solution doesn’t take effect;
Electrical engineer gave suggestion to connect the lifting motor with the general power source directly to test the motor itself, but it is not easy to do this, because the hoist has been installed on the building
Dongqi Hoist and Crane sincerely advise to assembly and do commissioning of all the parts before mounting the wire rope hoist, it is easier to do adjustment at ground.
At last, Dongqi Hoist and Crane shares the third solution: to check the power cable size, after confirm with client, Dongqi Hoist and Crane diagnoses that the power cable size is too small to support the wire rope hoist lifting, and it is better to replace of the small size electric hoist cable by bigger one. Finally, it works and the lifting motor returns to normal condition.
The case is very typical if clients choose to install the electric hoist by themselves. In addition, repeat wire rope hoist testing and commissioning is very necessary, especially for wire rope connections. If you have any problem, please send email to email@example.com or leave a message below.
Low headroom electric hoist is very popular with clients who has very limit space in their workshops. Due to the wire rope hoist is placed at one side of the crane bridge it can improve the lifting height and take full use of workshop space, with similar European design. the Low headroom electric hoist has very good performance during operation, but lower price comparing with European hoist, higher performance comparing with ordinary CD electric hoist, therefore, it is the first option among many clients.
Due to the low headroom electric wire rope hoist is installed on one side of the bridge and it is not balanced, there will be some steel scrap delivery with the low headroom hoist, some clients maybe don’t know this, when they see the scrap, they think it is the waste, and throw away. Actually, these scrap are balance weight for the low headroom hoist, it is used for level the other side, to make the electric hoist stable and balanced, the weight of the scrap is measured before delivery.
The scrap can also be replaced by stones, so if the scrap is thrown away accidently stones are the best replacement.
Overload limiter Is part of the electrical connection, it should be installed according to the manual and the position is general on top of the wire ropes, after installation, correct commissioning is very important, or it will show wrong figures to lead to danger. Correct commissioning method is to make the empty hook 1m from the ground and reset the overload limiter to Zero position, then following operation is safe and in order.
All the above cases are collected from client’s feedbacks, Dongqi Hoist and Crane expects to continue to improve itself through communicating with clients and providing the most suitable economical solutions for clients, if you have any questions, please feel free to contact us.
