Jib Crane

A jib crane is a lifting device with a horizontal or angled arm, called a jib, that supports a hoist and moves loads within a defined work area. Its jib rotates around a vertical mast or column, while the hoist travels along the arm to raise, lower, and position materials using mechanical or electric power. Jib cranes may be fixed, wall-mounted, or mobile, and their compact design provides localized lifting without requiring a full overhead crane system. In engineering, they improve material handling, assembly, and workstation ergonomics in manufacturing plants, warehouses, construction sites, and maintenance facilities.

Costing Methods: Job Order Costing

0 Views •

2026

Job order costing is a cost accounting system used to assign costs to specific and distinguishable jobs or projects. It is ideal for businesses that produce custom products or services, such as those in the construction, film production, and printing industries. Each job has its own unique requirements, which makes a standardized costing approach unsuitable.In this system, a job cost sheet is maintained for every individual project. This document captures all costs related to that job,...
