G.D. MacKay


As creators of the original Uni-Hoist line introduced in the mid-80s,    G.D. MacKay Co. Ltd. continues to manufacture these products in Winnipeg, Manitoba, Canada. Today we are pleased to report that the demand for Uni-Hoist is greater than ever! Heavy-duty and well- engineered, Uni-Hoist has proved itself to be nearly indestructible, earning its reputation of a quality product line a thousand times over.  To view the newest addition to the Uni-Hoist product line, our Personnel Winch, please see the video to the right.

A more advanced version of Uni-Hoist is our Fallsoft® product line, manufactured for G.D. MacKay Co. Ltd. by Winsafe Corp. out of Markham, Ontario, Canada. Since 2000, Winsafe’s engineering assistance has enabled us to develop new, lighter weight products that are ideal for overseas markets. We are proud of the fact that we currently have Fallsoft® customers in 6 of the 7 continents around the globe! Although we develop fall protection equipment for many different applications, we are especially knowledgeable about the industries below.

Utility Companies


We are currently selling to nearly 100 utility companies and transformer manufacturers. The bulk of this business is in Canada and the U.S. However, in recent years we have seen significant activity in Europe, the Mid- East, South Korea, China, and Taiwan. Because we do not advertise, we attribute this increase in overseas sales to the widespread use of the internet to locate product manufacturers.

Public Works


Most of the early business with the Uni-Hoist line was for Public Works, i.e., water departments, sewage, etc. Recently, we have noted a renewed interest in Uni-Hoist from various industries. During the time our focus was concentrated on developing the Fallsoft® product line with Winsafe, we lost touch with many Uni-Hoist customers. Now that safety professionals have become aware that we are still in business, the requests for Uni-Hoist quotations have risen significantly.

Shipping Containers


At the request of safety professionals in shipping terminals, the initial prototypes for the safety products used by stevedores in loading and unloading containers were developed in 2000. Now we can count 45 countries around the globe that utilize these products. In all likelihood, that number is even greater, since we are frequently unaware of the shipment destinations of orders from some distributors outside of North America.
