Planetary winch Drive: The planetary winch drive is designed to create a compact and flexible product that can withstand heavy loads. Even though it is built into the drum, the planetary reducer is easy to maintain. All connections are on the engine side. Capstan drives can be fitted with brakes and custom fittings to fit your system perfectly! RR Holland’s Planetary drive is a guaranteed durable product that meets high torque peaks.

Superior performance EP-NB40OW series winch drives planetary gear boxes can be installed in the winch drum as a gear reducer for the winch. Its performance conforms to the FEM M5 standard, and its maximum output speed is 25 RPM, which is the world standard for self-propelled and vehicle-mounted cranes. The EP-NB40OW series gearbox is the ideal solution for all lifting applications: our planetary gear is specially designed for use with a cable drum inside the winch drive, available with hydraulic and electric motor adapters. They have two tightly mounted flanges, one attached to the winch rack and the other fixed to the cable drum, so the drive housing acts as the main drum installation. The key Features1. Output torque range: 1000-280,000 N.m2. Gear ratio: I = 5.3-4003. Support: Gearbox has a rotating housing flange to fit winch 4. Applicable motor: axial piston hydraulic motor, hydraulic track motor, etc. 6. Hydraulic motor optional: reducing pressure valve, eccentric valve. Bearing: Rugged bearing system absorbs force applied by ring gear 7. Brakes: Hydraulic release parking brakes are available on request. The performance data refer to the maximum output of FEM standard M5 (T5-L2). The speed is 25 RPM. EP-NB40OW series gearbox technical parameters and installation dimensions are the same as the Rexroth GFT series gearbox. W series and Bonfiglioli 800 series, so these three can be used interchangeably.

 

This range covers torque ratings from 5.000 Nm to 400.000 Nm. It includes a rotary box gearbox designed to be mounted within the capstan drum. To ensure isostatic distribution of loads on the draw works, the gearbox is designed with a single support bearing. External negative static brakes help provide the required ease of maintenance in Marine applications. Some models have DNV type certification; Design approval can be obtained from other major classification societies as required.

 

One of the most common requirements for a winch or hoist is that it must operate within a limited footprint. This led to two initial design requirements; a Compact frame and an energy-efficient powertrain allow for the installation of a smaller power supply. These must be designed and manufactured in such a way that they also provide reliability, which is the product of many variables including raw materials, design expertise, and manufacturing capability. Why use a planetary capstan gearbox? Whether driven by hydraulic or electric prime movers, mechanical efficiency is the key to optimizing the performance of the winch gearbox. Some conventional gear systems can have mechanical efficiencies as low as 50%. By comparison, a single-stage planetary gearbox unit is about 98% efficient, even at very low speeds. In addition, the torque capacity of a planetary gearbox is superior to other solutions of the same physical size by distributing the load through multiple contacts (usually 3 or 4) between planetary gears (usually 3 or 4). In addition, EPT Motion Systems planetary gearboxes come in a variety of configurations and versions, often with high radial load capability from output bearings. This makes them ideal for indirect drive applications, or where the equipment must bear the load on the winch side. Drive systems take mobile cranes as an example. The common goal is to maximize lifting capacity while minimizing overall weight. In this regard, a correct winch drive can provide many benefits. Space can be at a premium, so the ideal solution is to mount the gearbox inside the capstan drum. By using planetary gearboxes, EPT Motion Systems has developed a very compact drive design that can provide strength and reliability in this situation.
