CASE STUDY | USA
The end user was looking for a method to lift, move and rotate 20ft by 8ft floating docks.
1,600lbs. They completed the material handling solution with a pair of aluminium lifting beams that they manufactured themselves. The customer 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 360º rotation to prevent twisting of the load chain, while 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 certificate and serial number. The customer added: “I made the
lifting beams from aluminium 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.”
The hoists and trolleys were sourced
along with a 2.0-ton capacity, adjustable aluminium gantry crane and lifting slings.
