Experience
Look for a company that has had at least a few years into the business and also a company that has provided crane parts for established companies. If established companies trust them for their products, why shouldn’t your company? An experienced company would know how to deal with its customers and products.
Service
Customer service starts from the point a customer calls in to a company for enquiries. For example, how long it takes for the company to answer his/her call and also how professional the worker on the phone is. Workers should be knowledgeable about the products and of the company.
Quality
Always look for quality and not quantity. Doesn’t mean when the item is cheap, means it is good. Most likely, cheaper items will wear off faster. Companies that sell crane spare parts also need to have a variety of products/brands for the customers to have choices. It is better to spend more money on a good and durable spare part rather than one that is cheap and highly likely would spoil faster.
