Rock Lifting Tongs

Lifting tongs for the extractive industry

For a company in the extractive sector, we designed adjustable lifting tongs to move blocks of stone, marble, and similar materials used in construction. The design of these clamps starts from the base of the Crosby Airpes coil lifting tongs, with specific adaptations so that the machine can carry out the operations requested by the client. Our rocklift solution is ideal for handling heavy materials efficiently in this industry.

These tongs also feature an easy chain hook system, allowing quick attachment and detachment for improved efficiency.

Adjustable lifting tongs available for rock blocks

The client needed lifting tongs to handle and manipulate marble and stone blocks extracted from a quarry and stored in the open air.

Since the type of material the company works with is not affected by weather, it can be stored anywhere without needing an enclosed space or complex security, custody, or preservation system.

This storage system is the most convenient, practical, and economically viable for any company in the sector: this saves costs on the maintenance of buildings and related infrastructure. Our grapple system is perfect for handling such heavy materials in an open storage environment, including boulder tuff.

Clamp installed on a gantry crane with wheels

For manipulating the blocks of material, the customer has a gantry crane with wheels powered by electric motors that can move freely throughout the storage site.

The gantry crane from our catalog can support weights of up to 42 tons. In this crane has been installed the lifting clamp, which has the following characteristics in order to make the client satisfied with the service that we make:

• Lifting capacity up to 25 tons for rock lifts
• Reinforced and waterproofed structure against water and  dust, designed to resist rust and corrosion in all weather conditions
• Ability to work outdoors and under all weather conditions
• Rotary hoist and beam for reorienting parts while in the air
• Adjustable arms with an opening and closing system to lift blocks of different widths
• Rotating arms: some pieces are not symmetrical, and one or both arms must be oriented at a different angle to lift such blocks.
• Anti-opening safety system: The clamp will not open if it detects that the object held by the rock tongs is not on the ground.
• An industrial radio-controlled system allows the machine to be operated from the ground.
• The lifting clamp also features rock retaining capabilities, ensuring that large stones and materials remain securely in place during lifting operations. Additionally, the clamp is designed to handle debris that may accumulate around the blocks during lifting.

1. Design and provide that lifting system that performs exactly what the customer needs.
2. The machine adapts to the customer’s working method and not the other way around
3. The product is known for perfection, which translates into the following points:

1. • Increased efficiency in scheduling revisions
