Hoists

Product catalog summary

Overview: GH has been manufacturing electric wire rope hoists and cranes for nearly 40 years, with over 40,000 installations in 37 countries. The company is recognized as a leading European manufacturer in the lifting sector.

Design Principles: The new range of GH hoists focuses on reliability, security, durability, affordability, and easy maintenance. The design is modern, compact, and modular, allowing for easy interchangeability of components to meet various lifting speeds, heights, and duty factors.

Construction Standards: GH hoists are constructed according to the Federation Europeenne de la Manutention (FEM) and IEC standards, ensuring compliance with international regulations.

Key Components:

Electrical Cabinet: Provides easy access to control components.
Wheels: Made from GG 60 or GGG 70 materials, depending on the model.
Push Button Pendant: Made from high-impact polypropylene, offering ergonomic design and double insulation.
Lifting Motor: Features a cylindrical short circuit motor with an electromagnetic brake, designed for continuous service.
Gearbox: Robust and compact, with helical teeth gears for silent operation.
Travelling Geared Motors: Designed for smooth acceleration and deceleration.
Drum & Cable Guide: Manufactured according to FEM 966 standards, with self-lubricating bearings.
Bottom Hook Block: Designed according to FEM 9661 standards.
Security Limit Switch: Prevents failure of the main limit switch.
Overload Limit Device: Includes an electromechanical load cell for safety.

Performance and Duty Classification: The hoists are classified according to FEM standards, considering duty type and operational time. The classification helps in selecting the appropriate hoist for specific applications.

Practical Example: A hoist with a capacity of 10,000 kgs, lifting height of 6 meters, and lifting speed of 5 m/min is classified as group 2 m (M5) based on its duty factor and operational time.

Options and Customizations: GH offers various mechanical and electrical options, including manual release brakes, thermic probes, anti-condensation heaters, remote control, and frequency inverter control.

Contact Information: GH is located in Beasain, Gipuzkoa, Spain, with contact details provided for further inquiries.
