ZT150Z-1AT 1.6-Ton Knuckle Boom Grab Crane

In confined spaces, bulk material handling is often constrained by equipment dimensions and operational range. Conventional lifting equipment frequently faces limitations in slewing (rotation) and struggles to handle materials at varying heights. The ZT150Z-1AT 1.6-ton grab crane, built on a proven knuckle boom architecture, overcomes these challenges by enabling multi-angle material handling in tight areas—boosting loading/unloading efficiency while reducing the need for manual labor on-site. This model features a maximum rated load of 1,600 kg (including the grab attachment), a maximum lifting moment of 15 ton-meters, and a maximum reach of 7.48 meters. It offers 380° continuous rotation, requires an installation footprint of just 850 mm, and has a net weight of 2,500 kg. Compared to telescopic boom cranes, the knuckle boom design occupies significantly less space when stowed. It is well-suited for applications such as log handling in forestry or scrap metal sorting at recycling facilities. The product line also includes ship-mounted telescopic and knuckle boom cranes, designed for grab operations on port decks and other marine environments.

Product Features

1. Extensive operational coverage: Features 380° continuous rotation and a wide luffing (boom angle) range, making it ideal for grabbing irregularly shaped materials at various heights and distances.

2. Reliable hydraulic system: Designed for a 40 kW power input, with a hydraulic flow rate of 80 L/min and an operating pressure of 26 MPa. Equipped with a 250L oil tank, it supports extended periods of continuous operation.

Usage Tips

1. Always verify the load against the load chart based on the current reach before operation to prevent overloading. Regularly apply grease to the slewing bearing and all hinge points.

2. This model is classified as a light-to-medium-duty grab crane; it is suitable for handling logs, scrap metal, and loose waste, but is not intended for the long-term handling of high-density, heavy, solid blocks.

FAQ

Q1: Can this grab machine be mounted on a truck chassis?

A1: The unit requires an installation space of 850mm and has a net weight of 2,500kg; it can be installed on any chassis that meets these specifications. Please provide your chassis parameters before purchase, and we will assist in verifying compatibility.

Q2: What is the hydraulic oil change interval, and what are the key points for daily maintenance?

A2: For a new machine, the first hydraulic oil change is required after 500 operating hours; subsequent changes should be performed every 1,000 operating hours. Daily inspections should focus on the sealing of hydraulic lines and the hinge points of the grab; any leaks or signs of wear should be addressed promptly.

Q3: What is covered under the after-sales warranty, and what is the warranty period?

A3: The warranty covers the main structural components and core original hydraulic parts for 12 months or 2,000 operating hours, whichever comes first. Damage resulting from overloading or unauthorized structural modifications is not covered.

Q4: Can the grab attachment be customized or selected based on specific needs?

A4: Yes, the grab attachment can be swapped to suit the material being handled—for example, using a log grapple or a scrap metal grapple. Please specify the type of material to be handled when placing your order, and we will provide the appropriate grab configuration.
