30 Tons Double Girder Gantry Crane Technical Parameters (Standard Model)

30 Tons Double Girder Gantry Crane Core Structural Features

The whole machine adopts a modular and optimized structural design, combining high-strength steel materials and sophisticated welding processes to ensure overall stability and durability. The main structure consists of double box girders, rigid and flexible support legs, end beams, traveling trolley, lifting winch system and electrical control system.

Double Girder Main Structure: The dual box-type main girders are the core load-bearing part of the crane, featuring high bending resistance, strong rigidity and small deformation under full load. Compared with single girder gantry cranes, the double girder structure supports larger working spans, higher lifting heights and more stable heavy-load operation, eliminating shaking and swaying during high-capacity lifting.

Optimized Support Leg Design: Equipped with A-type or U-type support legs (customizable), the structure is scientific and compact with strong wind resistance and ground adaptability. The rigid and flexible leg combination effectively relieves structural stress caused by temperature changes and track deviation, ensuring smooth traveling operation of the whole machine.

High-Performance Traveling & Lifting Mechanism: Matched with professional heavy-duty electric winch or electric hoist trolley, the lifting mechanism delivers stable lifting, precise positioning and low noise. The traveling mechanism adopts variable frequency drive (VFD) technology, realizing stepless speed regulation, smooth acceleration and deceleration, and no impact during operation, which protects the equipment and transported materials effectively.

30 Tons Double Girder Gantry Crane Advantages

• ◆ Heavy-Duty Bearing Capacity: Designed for 30-ton heavy-load continuous operation, it adapts to frequent lifting and long-time working conditions, meeting the high-intensity operational needs of ports, steel plants and large construction sites.
• ◆ Excellent Operational Stability & Precision: The integrated double girder structure greatly improves the overall stability of the crane. With precise trolley traveling and lifting control, it can accurately position heavy workpieces, suitable for precise assembly and material handling scenarios.
• ◆ Dual Control Modes for Flexibility: Supported by dual operation modes of wireless remote control and wired pendant control. Operators can choose the control method according to on-site working conditions, realizing flexible and convenient operation with a wide control range and high safety.
• ◆ Strong Environmental Adaptability: The whole machine adopts anti-corrosion paint and sealed electrical components, with good windproof, dustproof and rainproof performance. It can work stably in outdoor open yards, docks, construction sites and other harsh environments, not affected by conventional weather changes.
• ◆ Low Maintenance & Long Service Life: Adopting high-quality steel and standardized manufacturing processes, the equipment has low failure rate and strong wear resistance. Key components such as bearings and reducers are made of brand high-quality parts, reducing daily maintenance costs and extending the overall service life to more than 15 years under normal use.

Complete Safety Protection System

This 30-ton double girder gantry crane is equipped with a full set of intelligent safety protection devices to eliminate operational risks and ensure 100% safe operation:

• ◆ Overload Protection Device: Automatically cut off the lifting power when the load exceeds the rated 30-ton limit to prevent equipment overload damage and safety accidents.
• ◆ Travel & Lifting Limit Switches: Installed with upper and lower lifting limit switches and trolley traveling limit switches to avoid over-traveling and collision accidents.
• ◆ Emergency Stop Function: Equipped with emergency stop buttons on both the remote controller and pendant control, which can quickly cut off the power supply in case of abnormal conditions to stop all operations instantly.
• ◆ Voltage Loss & Zero Position Protection: Prevent automatic equipment startup after power recovery and avoid misoperation caused by zero-position failure.
• ◆ Anti-Collision & Windproof Devices: Fitted with buffer anti-collision devices at the ends of the track and professional windproof clamps and rail grippers to prevent equipment sliding and collision in strong wind.
