Product Overview

Radial piston cam-lobe hydraulic motor, 1,091–2,812 cc/rev displacement range, 17,900 Nm max torque at 450 bar, 70 kW power, 170 RPM top speed. The MS18-2-2812-L18-2A60-F05 is the big-displacement workhorse of Poclain's modular MS platform — built for the heaviest direct-drive rotary applications where massive breakout torque and sustained high-pressure operation are non-negotiable. Dual-displacement switching provides full torque for grinding, crushing, and winching, plus higher-speed repositioning mode, all without a gearbox. Available as shaft motor or integrated wheel motor with TwinLock anti-skid, parking brake, and service brake options. Typical deployments: large-diameter augers, industrial shredders, marine mooring winches, tunnel boring machine auxiliary drives, heavy tracked carriers, and stationary mill drives across mining, construction, and material handling sectors.

Key Features

• Mature cam lobe radial piston structure Adopts proven Poclain cam lobe technology, generates ultra-high torque at low speed to meet extreme heavy load drive requirements for oversized machinery.

• 2812cc extra-large displacement design Delivers far higher torque output than medium and small displacement motors, suitable for continuous operation under ultimate heavy load scenarios.

• 1:1 OEM interchangeable mounting dimensions Flange, drive shaft and oil port layout match original MS18/MSE18 specifications perfectly, no on-site machining required for replacement installation.

• High-strength forged alloy steel internal components Carburized cam rings and precision machined pistons withstand repeated severe impact loads, prolong service life on rough mining and construction sites.

• Heavy-duty composite sealing assembly Combined PTFE and nitrile seals tolerate high pressure and temperature variation, lower oil leakage and maintain stable volumetric efficiency over long working cycles.

• Direct wheel hub mounting capability Direct installation on wheel hubs or drive rollers eliminates external gear reducers, saving installation space and overall system investment.

• Stable bidirectional rotation Supports clockwise and counter-clockwise operation, ideal for reversible equipment including ultra-large track drives, heavy marine winches and heavy-duty conveyors.

• Superb harsh environment adaptability Thick reinforced alloy steel housing resists dust, moisture and strong mechanical vibration, reliable for mines, quarries and large construction sites.

• Strict factory bench quality testing Each motor passes pressure endurance, efficiency and leakage inspection prior to shipment to satisfy international export quality standards.

• Wide heavy industrial application range Applicable for ultra-large construction vehicles, heavy mining transporters, large harvesters, port bulk handling machinery and marine hydraulic winch systems.
