Pls Click Here for Excavator Attachment Catalog.pd...
Excavator quick hitches typically consist of two parts: a coupler that attaches to the excavator arm, and a set of pins or lugs that attach to the attachment. The coupler and pins are designed to fit together securely, allowing the attachment to be quickly and safely connected to the excavator.
Using a quick hitch can save time and increase efficiency on construction sites by allowing the operator to switch between attachments, such as buckets, breakers, and thumbs, without having to stop work and manually change them. However, it is important to use the correct quick hitch for a given excavator and attachment to ensure proper fit and safety.
1. Durability: Manual quick couplers are typically made from high-strength steel or other durable materials to withstand the harsh conditions of construction and excavation work.
2. Ease of use: While manual quick couplers may be less convenient than hydraulic couplers, they are designed to be easy to use and require minimal training or expertise to operate.
3. Maintenance requirements: Manual quick couplers typically require minimal maintenance and are designed to be easy to clean and inspect. Regular inspections and maintenance can help ensure safe and reliable operation over the long term.
