Dinamic Oil designs all of its planetary hoists to conform to UNI ISO 4301/1 Classification for Cranes and Lifting Appliances. As part of our own internal validation process our hoists are subject to scrupulous fatigue, dynamic, overload and destructive tests, making our hoists well sought after for mission critical applications.
The A Series is Dinamic Oil’s response to the US Hoist Distribution market, but with noticeable improvements. The Series ranges from 1,000 – 21,000 lbs of drum Line Pull and was designed with our flexible thinking approach. The hoist supports were pre-drilled to accommodate the ordering and installation of optional accessories in the field (Cable Tensioners, Last Wrap Indicators) and our comprehensive US based stock and hoist test bay ensures we can design and modify the motor mount and drum configuration locally. The drums can be smooth, helical or with A-Synchronous grooving. The motors can be Orbit, Gear or Axial Piston. The Series is completed with our proprietary negative static disc brakes and sprag clutch.
The SRD Series of hoists are designed with flexibility in mind using our WD Series Winch Drives. By exploiting our complete range of planetary gearboxes, Dinamic Oil possess’s the internal building blocks to customize SRD hoists with Line Pulls of 16,000 – 70,000 lbs and for any application. Customers will immediately appreciate the power of this winning combination that allows us to rapidly design and produce Turnkey Customized Hoists with ratios between 15 and 500:1, inline, or right angle configurations, with inputs for hydraulic, electric or mechanical drives and a full complement of accessories (Cable Tensioners, Aux & Band Brakes, Electronic Load Detection Systems, Last Wrap Indicators and encoders).
The WDD Series are semi complete Winch Drives, with a drum and outboard bearing support. This personalized solution offers the ability to fit the drum directly into the crane structure.
The NP Series was designed for low Line Pull applications that require an extremely compact, economical but efficient solution. The drum is integral to the planetary ring gear ensuring a compact design and increased Line Pull/ weight ratio.
The P Series hoists achieved success on the market with their innovative design whereby the motor, and counter balance valve are almost entirely hidden inside the drum. When space is a limiting factor, the P Series excels.
Planetary Hoists are composed of 5 major components and optional accessories.
Motor – The drive motor can be hydraulic, pneumatic, electric or mechanical.
Counter Balance Valve – The valve is a core component of the hoist assembly that dynamically controls the load when lowering to ensure every lift is safe and secure.
Negative Static Multi Disc Brake – The brake is composed of alternating bronze and steel discs connected to the motor drive shaft and the hoist body. The brake is controlled by a counter balance valve that ensures safe opening and closing of the static brake. An optional sprag clutch can be used when additional safety precautions are required.
Planetary Gearbox – the high efficiency planetary gearbox inside the hoist develops the torque necessary to lift maximum loads. Our hoists are typically designed with 2 or 3 reduction stages with ratios between 4:1 and 150:1, however, contrary to many traditional hoist manufacturers, due to the depth of ratios available to Dinamic Oil, there are no limits to our ratio options.
Drum and Support Structure – the drum and support structure can be high quality cast iron or laser cut structural steel.
