Explore workstation overhead cranes, including bridge and floor-mounted supports, hoist, trolley, pendant control, and electrification. Learn safe operation steps, set-up, lift planning, and efficiency benefits.

Explore five jib crane types: wall mounted, freestanding, articulating, mast style, and workstation, and learn their load capacities, applications, and selection factors for efficient material handling.

Operate freestanding jib cranes by supporting a vertical column on a concrete foundation, with a horizontal jib, hoist, trolley, and cable to lift and move loads within a defined radius.

Describe how a wall mounted jib crane attaches to a wall and extends the jib to lift loads within a radius using hoist, trolley, and cable. Capacities range £250–£10,000.

Mast mounted jib cranes use a horizontal jib on a vertical mast with a hoist and trolley to lift and move loads within a defined radius.

Explore articulated jib cranes, featuring a vertical mast, mobile base, and adjustable jib with a hoist and trolley to lift and move loads across manufacturing, warehousing, and transport.

Explore gantry jib cranes with a mobile base, rotating jib, and hoist to lift loads precisely, and review capacities and use in manufacturing, construction, and transportation with basic operation steps.

Explore wall travelling jib cranes, the sixth type mounted on a wall track that rotates on its axis to lift and move loads with a hoist, trolley, and cable.

Explore how jib cranes use leverage to lift and move loads, with a rotating jib, trolley, and hoist powered by an electric motor. See wall, floor, and ceiling mounting variations.

Assess how jib cranes boost efficiency and safety, offer versatility, space saving, and precise placement. Evaluate limits such as range, load capacity, cost, installation, and maintenance to judge suitability.

Inspect jib cranes before operation, verify load capacity and sling integrity, secure the load, and lift slowly, moving and lowering with steady control per manufacturer instructions.

Explore floating cranes and crane vessels in marine environments, covering offshore construction, oil and gas exploration, port operations, salvage, and key types like heavy lift and container crane vessels.

Learn how heavy lift vessels function as specialized ships with heavy duty cranes to lift and transport heavy loads offshore, including oil and gas equipment, up to one lakh tonnes.
