| Hoist Design | |
 A
New Conception - Future TechnologyFor nearly 40 years, GH has been manufacturing hoists and other lifting equipment. During this time we have made more than 40,000 installations, from which we have gained valuable experience. The new range of GH hoists have been designed with the following principles; reliability, security, durability, price and easy maintenance. The design is rectangular, modern, and compact with perfect dimensional balance. |

Gear Box Robust
and compact, situated on the exterior, allowing ease of access.The helical teeth in all the gears are cut with great precision, in cemented steel, assuring silent running, great reliability an long life. The drive from the motor to the gearbox is direct, avoiding coupling devices which have tendency to fail. All of the gears are lubricated by an oil bath in the interior of a closed casing, machining of the gear locations is made by high precision machine tools. |

Lifting
Motor 
The hoist has a cylindrical short circuit motor with an incorporated
electromagnetic brake. The motor and brake have been designed for continuous service with high duty factors and cycles. The brakes are electromagnetic disc, with asbestos free flat-faced linings. Thy offer great reliability and automatic braking in the event of power failure. The friction linings are long lasting ad the brake is easy to regulate. The standard version motor has the option of one or two speeds. The second speed has a relation of 1/6. Also upon customer request, we can supply inverter control or motors. |

Drum
& Cable Guide
The drum is designed and manufactured according to FEM 966 standard.Constructed from a seamless steel tube with grooves machined according to DIN 15061. The groove is machined dependant on the wire rope exits i.e. or 2 exits. The drum is fitted to the hoist frame using thigh quality, self-lubrication, commercial bearings. The drive from the gearbox to the drum is via a direct splined shaft. The rope guide is manufactured from GGG 70 nodular cast iron with self lubrication graphite, which also gives particular resistance to wear. The rope guide is formed by two pieces, which can easily be assembled without special tools. |
