Product catalog summary

Overview

This document presents technical specifications, features, and operational details of GH's range of automotive marine gantry cranes and marine jib cranes. The cranes cover lifting capacities from 4 to 300 tons, designed for robustness, ease of use, maintenance, and adaptability to various boat types.

1. Product Range and Capacities

Rotating Arm Cranes: Modular construction allows cranes with capacities from 4 to 20 tons and arm lengths up to 7 meters, emphasizing simplicity and maneuverability.
Automotive Marine Gantries: Wide variety available from 20 to 300 tons capacity, characterized by robustness, easy maintenance, and maneuverability.
Marine Jib Cranes: Four models with arm lengths ranging from 4 to 7 meters and lifting capacities from 4 to 7 tons.

2. Technical Specifications

Dimensions and Capacities: Detailed dimensions for models JP1 to JP4 and GH series (GH-25 to GH-300) including lifting capacities, arm lengths, column heights, and turning radii.
Turning Radius: Defined by the diagonal distance between outer points of wheels, with optional 4-wheel steering for improved maneuverability.
Sling Angles and Capacities: Sling angles of 15°, 20°, 25°, and 30° affect lifting capacities, with tables indicating maximum loads and sling lengths.

3. Structural and Mechanical Features

Articulated Connections: Designed to absorb torsional moments and ensure proper wheel alignment and surface contact.
Hydraulic Systems: Include hydraulic motors for long travel movement, hydraulic distribution systems for maneuvering, and safety valves on distributors.
Steering: Automatic steering alignment with optional 4-wheel steering enhances control.
Spreader Design: Central anchorage for sling positioning to ensure load stability.

4. Materials and Finishing

Painting: Surface preparation by blasting to SA 2 1/2 grade, followed by a three-layer coating: epoxy primer, epoxy intermediate, and polyurethane enamel with a minimum thickness of 180 microns.
Hydraulic Piping: Precision stainless steel pipes conforming to DIN-3291 standard to prevent corrosion and ensure durability.
Bolted Structure: Designed for easy assembly with water-tight seals to prevent corrosion at screwed connections.

5. Safety and Control Systems

Radio Control: Equipped with transmitter and receiver for remote operation.
Safety Valves: Incorporated in hydraulic distributors to ensure operational safety.
ISO 9001 Certification: Quality management system certification ensuring product reliability.

6. Acoustic and Environmental Compliance

Soundproof Power Unit: Designed to meet Directive 2000/14/CE with acoustic power level LWA of 94 dB(A), equivalent to 66 dB(A) at 10 meters, suitable for outdoor use.
