Crane Track Undercarriage

Guide to Crawler Crane Undercarriage Parts

Introduction

The undercarriage of a crawler crane is a critical component that provides stability, mobility, and support, enabling the crane to operate efficiently in various terrains. This guide will delve into the key parts of the crawler crane undercarriage, their functions, and the importance of maintenance.

Main Components of Crawler Crane Undercarriage

1. Crawler Crane Track

The track is a fundamental part of the undercarriage, consisting of flexible chain links driven by the sprocket and supported by track rollers, idlers, and tensioning wheels. The tracks are constructed with track plates and track pins, where the track pins connect the track plates to form a continuous track chain. The track plates have holes that engage with the drive wheel and feature idler teeth to guide the track and prevent disengagement. Reinforced anti-slip lugs on the track plates enhance durability and traction[1][2][5].

2. Sprocket

The sprocket is typically positioned at the rear of the crawler machinery and plays several crucial roles:
– It shortens the length of the track drive section, reducing friction and wear on the track pins.
– It prevents the formation of a raised portion in the lower part of the track, ensuring the track remains securely in place during turns.
– It contributes to improving the efficiency of the walking system by keeping the center of gravity low[1][2].

3. Tensioning Device

The tensioning device is essential for maintaining proper tension in the track chains. This ensures optimal alignment, reduces slack, and prevents excessive wear or damage. The main tensioning components include tensioning rollers and mechanisms[1][2].

4. Idler

The idler is usually positioned at the front or rear, depending on the sprocket’s placement. Its primary function is to guide the track in the correct rotation and prevent deviation or derailment. The idler helps maintain tension within the system and ensures proper alignment of the track chains[1][2].

5. Track Roller

Track rollers are cylindrical components that support the weight of the crane and ensure smooth movement along the tracks. They are made of durable materials like steel and are designed to withstand heavy loads. Each track roller consists of an outer shell housing bearings or bushings, allowing the roller to rotate freely. The number and arrangement of track rollers depend on the crane’s size and design, ensuring even distribution of the crane’s weight[1][2][4].

6. Buffer Spring and Walking Mechanism

The buffer spring helps in absorbing shocks and maintaining stability, while the walking mechanism enables the crane to move independently on both front and rear tracks, allowing for a smaller turning radius[1].

Working Principle of Crawler Crane Undercarriage

The operation of the crawler crane undercarriage involves the following steps:
– The motor drives the rotation of the sprocket.
– The torque from the gearbox causes the sprocket’s teeth to engage with the links of the track chain, continuously rolling the track from the rear.
– The portion of the track in contact with the ground exerts a backward force, and the ground provides a forward reaction force, propelling the machine forward.
– The track rollers roll forward on the surface of the track, enabling the machine to move[1].

Maintenance of Crawler Crane Undercarriage

Regular maintenance is crucial to keep the crawler crane running in top condition:

Inspect Tracks and Components

Regularly inspect the tracks and components for wear. High-pitched noises or squealing indicate wear points that need attention[4].
