LANTEC LH Series personnel handling rating: While LANTEC LH Series Hoists are generally NOT intended for personnel handling, special configurations are available for use on offshore cranes operated under the provisions of the American Petroleum Institute (API) Specification 2C. Please consult the factory.

LANTEC LH Series Hoists and LW Series Winches utilize a gear motor designed for performance characteristics specifically suited to hoisting and winching applications.

For high-pressure hydraulic systems on mobile or offshore cranes and equipment employing piston pumps and high-grade system components, we offer SAE C or D motor mounting configurations.

LANTEC can supply the hoist or winch with a variety of motor types and sizes to best match your system configuration and performance needs. Some crane and equipment manufacturers prefer to retain complete system responsibility. Therefore, LANTEC offers the hoist or winch shipped from the factory without a motor. This allows the customer to supply the Motor and Brake Valve that best suits the application.

  • Brake Valve: LANTEC’s Brake Valve is the industry’s most stable and reliable, designed for high efficiency and capable of very high flow rates. Valve orifices are kept free from clogging with a built-in high-grade filter, reducing the probability of downtime due to a malfunctioning Brake Valve, one of the most common problems in the field. LANTEC LH Series Hoists are designed to save you money over the long term.
  • High Design Factor: Pull tests (witnessed by ABS) on Model LHS160 proved that the representative hoist could withstand well over 3 times its rated drum torque without failure. This is indicative of LANTEC’s conservative design approach.
  • Sprag Clutch: LANTEC LH Series Hoists employ a high-capacity, long-life Sprag Clutch. LANTEC’s Sprag Clutch incorporates a state-of-the-art, antirollover feature ensuring positive holding even under very high overload conditions.
  • Brake Springs: LANTEC LH Series Hoists offer the added safety of redundancy in the brake springs. LANTEC uses 12 compression-type coil springs in parallel. These die springs are designed for use in the demanding mold industry and exhibit a long life at very high cycles. In the unlikely event, several springs were to fail, LANTEC’s brake still retains sufficient capacity to stop and hold the load.
    • In comparison, the competition utilizes a single coil spring or a single stack of washer-type springs stacked in a series. Brake capacity is lost with the failure of even on spring.
  • Self Contained Drive Modules: Most LANTEC LH Series Hoist models are designed with the complete drive module removable as a single package. This feature helps maintain alignment of drive components and provides for faster, easier field service and convenient core exchange.
  • Modular Design: LANTEC LH Series Hoists use many common components throughout the LH Series Hoist line, resulting in lower spare parts inventory cost. For example, the complete brake module is identical for all LH Series Hoists.
  • Larger, Longer Life Gearing: LANTEC puts more gear capacity in LH Series Hoists, providing you with a long life and a higher degree of reliability.
  • Replaceable Planet Bearings: LANTEC LH Series Hoists employ only complete roller bearings in the Planetary Gears, providing the benefit of low-cost replacement of the bearings without having to replace the Planet  Gear and the Planet Pin. With our competitors, replacing a Planet Bearing means an expensive replacement of the Planet Gear and Planet Pin, in addition to the bearing itself. LANTEC saves you money in the long term.
  • Motor Mountings: LANTEC LH Series Hoists accommodate both SAE C and SAE D hydraulic motor frames.
  • One Seal Kit: LANTEC LH Series Hoists use one Seal Kit to cover the complete LH Series Hoist line, offering the advantage of stocking fewer standby parts and reducing inventory costs.
  • Seal Running Surfaces: LANTEC LH Series Hoists include corrosion-resistant running surfaces for all oil seals, offering long seal life even in demanding, marine environments. This important feature means that  expensive parts won’t need to be replaced due to corrosion of the seal running surface and subsequent seal failure. This reduces the danger of running the hoist without oil, lowers the cost of downtime and the  environmental risk of an oil leak.
  • Gear Ratios: LANTEC LH Series Hoists have a broad selection of gear ratios. This allows better matching of the hoist to your exacting requirements.
  • Robust Base: LANTEC LH Series Hoists use cast base components and heavy-duty cast tie bars, providing excellent assembly alignment and a more rigid base for handling and mounting. The higher torsional stiffness helps to keep internal parts aligned when under load. In addition, the tie bars are resistant to corrosion compared to the thin, steel plate used by our competitors.
  • Optional Drum Sizes: LANTEC LH Series Hoists offer a more extensive list of standard drum sizes. Custom drum sizes are available with reasonable delivery at an attractive price for your special applications.
  • Exclusive “No-Spill” Oil Change System: Most LANTEC LH Series Hoists include a self-contained, “No-Spill” oil change system for faster and environmentally friendly oil changes. Using ordinary tools, the self-contained oil drain tube is extended from the drum to the outside of the hoist, making oil changes convenient, safe and consistent with good environmental practice.
  • Magnetic Plug: LANTEC LH Series Hoistsinclude a heavy-duty magnet, extending into the oil sump. This magnet is built into the large oil fill plug and is easily removed for inspection. The magnet traps significant metal particles contained in the oil, resulting in better lubricating properties and longer component life. The quantity of particulate on the magnet, together with periodic oil sample analysis, is a good diagnostic tool that can provide an indication of wear inside the hoist.
  • Ratchet & Pawl: For boom handling, LANTEC LH Series Hoists are available with a Ratchet and Pawl for positive locking of the drum. (Field installable Ratchet and Pawl Kits are also available.) On LH Series Hoists, the complete Pawl package is mounted within the hoist base. Competitor products have the pawl mounted separately, bolted to the crane itself. You save money with LANTEC by having far lower installation costs, not to mention saving the cost of having to periodically inspect and adjust the alignment of the Pawl to the Ratchet.
  • Interchangeability: LANTEC LH Series Hoists have identical foot mounting dimensions to many competitor hoists, allowing easy field replacement with the superior LANTEC LH Series Hoist. Line pulls and line speeds are comparable, or better. In general, drum sizes and wire rope capacities are comparable.
