The Winona, Minnesota-based manufacturer provided the equipment via distributor Global Industrial, delivering it to the end user’s yard in Seattle, Washington. The hoists and trolleys were sourced along with a 2-ton capacity, adjustable aluminum gantry crane and lifting slings.
The customer was looking for a method to lift, move and rotate 20 ft. by 8 ft. floating docks, which weigh between 600 lbs. and 1,600 lbs. He completed the material handling solution with a pair of aluminum lifting beams that he manufactured himself.
He said: “The dock sections are too big and heavy to move, even with two people. Usually, I need six people to lift a single section and I don’t have that type of manpower readily available. The overall solution has proved to be very helpful; it is super easy to raise, lower and move my dock sections—and other heavy objects—around the property.”
The hoists, operated by ergonomic pendant control, offer overload protection; a high-performance friction clutch is integrated with the load brake. Each hoist features a forged carbon steel load hook with a heavy-duty latch. The bottom hooks, meanwhile, feature a thrust bearing to allow 360-degree rotation to prevent twisting of the load chain; the top hook is rigid.
The load sheave provides better distribution of the floating dock load, and smooth lifting with reduced vibration and wear, while the precision-machined gears are heat-treated for strength and durability. Oil bath lubrication on all bearing rotating points presents the end user with quieter, smoother, and cooler operation, and 110v power (115/1/60) means the hoists can be used virtually anywhere.
The trolleys boast lightweight robust construction, and fit most I-, S-, and W-beams. They are protected by baked enamel paint and feature precision ball-bearing trolley wheels, anti-drop plate, and stainless steel identification tags. All OZ products are delivered with individual test certificates and serial numbers.
The customer added: “I made the lifting beams from aluminum and included hooks for the lifting straps. I can use the gantry on wheels to move it around the property, but it can also transport the docks while under load. [The equipment] allows me to also upend and rotate the load.”
