GP 8t by MacGregor is a general-purpose marine crane in the GP range for stores, service and miscellaneous deck lifting. MacGregor GP cranes are self-contained electro-hydraulic units using a closed-loop hydraulic system for hoisting, luffing and slewing control. They are typically mounted on a pedestal on an exposed deck where provisions, spare parts and service loads must be transferred between ship and quay or supply craft. The crane package includes the structural crane, hydraulic power and motion-control equipment, with limit and remote-control features depending on the vessel specification. This entry is the 8t variant in the GP family, distinguishing it from neighbouring GP models by its listed lifting-capacity designation while retaining the same general service role. The exact outreach, reeving, hook arrangement and operating limits must be taken from the crane certificate and manufacturer documentation.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect wire ropes, hooks, sheaves, brakes, hydraulic hoses, cylinders, pedestal bolts, slewing structure and all safety/limit devices under the vessel lifting-gear PMS. Keep hydraulic oil clean and at the specified condition, investigate leakage promptly and function-test emergency stop and motion limits before critical lifts. Carry out structural and load-related examinations in accordance with flag, class and the vessel lifting-gear register. Any brake setting, discard criterion or test load must come from the approved crane documentation; refer to the manufacturer documentation for the exact figure.
Hold hydraulic hose and seal kits, filters, control switches or relays used by the installed crane, brake wear parts and selected wire-rope/sheave service items. For remote trading, stock the small electrical and hydraulic components whose failure would disable all crane motions.
