Bolted Type Come Along Clamps

The Bolted Type Come Along Clamp is a rugged and adjustable wire grip tool used extensively in Overhead Equipment (OHE) work in the railway sector. Designed to hold and pull conductors like contact wire and catenary wire during stringing and tensioning operations, this clamp features a bolted mechanism for manually securing the conductor within serrated jaws.

Unlike auto-grip clamps, the bolted type offers manual adjustability for varied conductor sizes and is preferred in situations where a firm, customizable grip is essential. It is widely used by railway traction maintenance and installation teams.

Key Features:

• Design Type: Manually tightened with high-tensile bolts for secure locking

• Material: Heavy-duty forged steel or alloy steel with rust-resistant finish

• Jaw Design: Serrated or grooved gripping surfaces to ensure no conductor slippage

• Conductor Compatibility: Suitable for standard railway OHE conductors (e.g., 65, 107, 130 sq.mm)

• Load Capacity: Typically supports loads of 1.5–3 tons, depending on design

• Ease of Use: Simple mechanical design allows for field-level maintenance and operation

• Safety: Secure bolted locking prevents accidental release during tensioning

Applications in Railway Sector:

• Used for tensioning and alignment of overhead contact wires and catenary wires

• Suitable for both new electrification projects and maintenance work

• Common in traction depots, OHE gangs, and trackside repair operations

Advantages:

• Adjustable to various conductor sizes

• Strong and reliable mechanical grip

• Durable construction for rugged field conditions

• Cost-effective and easy to maintain
