ZB-A Column Jib Crane for Precision Lifting

Product Overview

ZB-A Type Column-Mounted Jib Crane (ZB-A Type Fixed-Column Jib Crane), also known as a swing crane or fixed-column jib crane, is designed with a rated lifting capacity of 0.25 to 5 tons. The hoisting mechanism can adopt wire-rope type single/double speed electric hoists or chain hoists. It is a medium and light-duty lifting and transporting equipment developed in recent years. The ZB-A Type column-mounted jib crane features a unique structure, reliable safety, and is characterized by high efficiency, energy saving, time saving, labor saving, and flexibility. It can be operated freely in three-dimensional space, and demonstrates superior performance over other conventional lifting equipment in short-distance, high-density handling applications.

Product Features

Five-Dimensional Precision Sizing: The ZB-A series provides a complete five-dimensional dimensional parameter system covering L/R₂/R₁/H/h, enabling precise selection based on workstation space and effectively preventing interference between the jib arm and workshop columns or equipment.
Multi-Hoist Compatibility: Six capacity tiers from 0.25 to 5 tons, compatible with wire rope single/double speed hoists and chain hoists, flexibly matching various lifting requirements.
Precise Dual-Speed Lifting: Lifting speed selectable between normal and slow modes (4/1, 8/2, 8/0.8 m/min), with the slow speed mode suited for precision assembly and mold installation applications.
Predictable Installation Planning: Complete dimensional drawings are provided, allowing foundation construction and equipment installation to proceed in parallel, shortening project timelines.
Strong Non-Standard Design Capability: Lifting capacity, radius of rotation, lifting height, and control methods can all be customized to meet workstation requirements.
Comprehensive Safety Configuration: Multiple safety devices including lifting limit switches, emergency stop, and overload protection.

How It Works

The ZB-A fixed-column jib crane operates as follows: the column is secured to a concrete foundation via anchor bolts, and the jib arm connects to the column through a slewing mechanism. The jib arm rotates around the column via either an electric slewing drive or manual operation, while the attached hoist (wire rope electric hoist or chain hoist) travels horizontally along the jib arm's rail. During lifting, the electric hoist raises the load vertically, and the jib arm's rotation transfers the load horizontally to the target position, enabling full-coverage lifting within the workstation.

Product Structure

The ZB-A column-mounted jib crane consists of the following core components:
Column: Fixed to the concrete foundation, serving as the load-bearing core of the entire unit.
Jib: Connected to the column via a slewing bearing, enabling flexible rotation.
Slewing Mechanism: Electric or manual slewing drive that ensures smooth rotation of the jib.
Hoisting Mechanism: Wire rope single/double speed electric hoist or chain electric hoist, mounted on the jib rail.
Electrical Control System: Wired push-button control or wireless remote control, including hoisting limit control.
Safety Devices: Hoisting limit switch, emergency stop button, etc.

Technical Specifications

The table above lists the technical specifications for the ZB-A series 0.25~5t jib cranes, including rated lifting capacity, hoisting speed (normal/slow), slewing speed, and overall dimensions (L/R₂/R₁/H/h) for each model. When selecting a model, the workspace and lifting range at the job site should be considered to determine the appropriate unit.

Applicable Scenarios

The ZB-A jib crane is suitable for various workplaces across different industries:
Factory workshops: Material handling and process transfer on production lines.
Warehouses: Loading, unloading, and handling of heavy items.
Assembly lines: Lifting and positioning of workpieces during assembly.
Machine tool loading/unloading: Handling of heavy workpieces on machining centers, lathes, and other equipment.
Docks and freight yards: Lifting operations for light cargo.
Maintenance shops: Hoisting operations during equipment repairs.

Operating Instructions

Pre-Operation Inspection: Check whether the wire rope/chain of the electric hoist is intact, whether the limit switches function properly, whether the slewing mechanism produces any abnormal noise, and whether the anchor bolts are tightened.
Startup and Operation: Connect the power supply, and control hoisting, trolley travel, and jib slewing via the wired push-button pendant or wireless remote control.
Lifting and Handling: Keep the load stable during lifting, watch out for nearby personnel and obstacles when slewing the jib, and never exceed the rated capacity.
Shutdown and Maintenance: After completing the work, park the hoist at the designated position and disconnect the power supply. Periodically inspect the slewing ring lubrication, bolt tightening condition, and electrical wiring insulation.

Frequently Asked Questions

Q: What do L, R₂, R₁, H, and h represent in the ZB-A dimensional parameter table?
A: L is the total jib length (from slewing center to lifting point), R₂ is the maximum working radius, R₁ is the minimum working radius, H is the column top height, and h is the effective lifting height. When selecting a model, refer to the table based on the workstation space dimensions to ensure the jib's rotation does not interfere with workshop columns or equipment.

Q: What is the difference between the ZB-A and BZD models of pillar-mounted jib cranes?
A: The ZB-A is a standard series model of jib crane. Like the BZD, it features a pillar-mounted design, but the two differ in model designation and dimensional specifications. The ZB-A offers more detailed overall dimension configurations (L/R₂/R₁/H/h) to accommodate various workstation space layouts.

Q: Which manufacturing and acceptance standards does the ZB-A jib crane comply with?
A: The design and manufacturing follow GB/T 3811 "Specification for Design of Cranes" and JB/T 8906 "Slewing Cranes" standards, with dimensional accuracy controlled per GB/T 1804 "General Tolerances", and safety devices meeting the relevant requirements of TSG Q7014.

Q: How much does a ZB-A column jib crane cost?
A: The price varies by lifting capacity and jib radius. Small units with 0.25~0.5 t capacity range from RMB 8,000 to 18,000; medium units with 1~2 t capacity range from RMB 20,000 to 40,000; large units with 3~5 t capacity range from RMB 35,000 to 70,000. The exact quote depends on non-standard requirements such as jib radius, lifting height, and special features.
