Electric wire rope hoists will encounter various problems during the installation process. Due to the COVID-19 epidemic, our engineers are often unable to go to the country where customers are located to help install electric hoists. Therefore, when customers encounter problems in installation, our engineers will Need to remotely guide customers to find problems and give solutions. Today we share a case from a building materials factory in Manila, Philippines, where our customer customized a 2 ton electric wire rope hoist.
Electric wire rope hoist specifications:
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 hoist traveling is normal, but the lifting motor has no action.
We technically advise to check the wire connections and test each point of 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(we sincerely advise to assembly and do commissioning of all the parts before mounting the hoist, it is easier to do adjustment at ground). At last, we shares the third solution: to check the power cable size, after confirm with client, we judge that the power cable size is too small to support the hoist lifting, take replace of the small size cable by bigger one, the lifting motor returns to normal condition.
This is a very typical electric wire rope hoist installation case, if clients choose to install the hoist by themselves, we must stress again that repeat testing and commissioning is very necessary especially for wire connections.
