High Quality and Cheap Price Medium-Duty20 Ton 30 M Straight Arm Telescopic Boom Deck Crane Marine Offshore Ship Deck Cranes

Product introduction:

Basic Parameters

• Lifting Capacity: 20 tons (t)

• Working Radius: Up to 30 meters (m) maximum, with specific working radii potentially adjusted according to the crane's design and configuration.

Features

1. Telescopic Straight Boom: The crane adopts a telescopic straight boom design, allowing for adjustable boom length based on actual needs, thus accommodating various heights in lifting operations. This design not only enhances the crane's flexibility but also optimizes space utilization.

2. High-Strength Materials: Crucial components such as the boom and outriggers are typically crafted from high-strength materials like manganese steel, ensuring the crane's load-bearing capacity and longevity.

3. Hydraulic Drive: The telescopic straight boom crane utilizes a hydraulic drive system, which harnesses hydraulic pumps and motors to execute the boom's extension, retraction, lifting, and rotation. The hydraulic system boasts smooth power transmission and ease of control.

Operating Principle

The operating principle of the telescopic straight boom crane is outlined as follows:

1. Initiate the hydraulic pump to feed hydraulic oil into the hydraulic system.

2. The hydraulic system then powers the hydraulic motor, which subsequently activates the boom's telescoping mechanism for extension or retraction.

3. Concurrently, the hydraulic system operates the winch mechanism, leveraging wire ropes and other transmission components to lift or lower the hook.

4. The rotation of the boom is achieved through a slewing mechanism, commonly driven by a hydraulic motor connected to a worm gear reducer or similar components.

Application Fields

The 5t12m telescopic straight boom crane finds extensive applications across various sectors, including:

• Port Handling: Utilized in port terminals and docks for lifting and transporting containers, cargo, and more.

• Construction: On construction sites, it facilitates the lifting of building materials, installation of equipment, and other lifting tasks.

• Mining: In the mining industry, it is employed for lifting ore, mine cars, and other heavy loads.
