EVO Synchronous Lifting System lifts a 200 tonne wheel loader safely and efficiently despite uneven ground

EVO Synchronous Lifting System lifts a 200 tonne wheel loader safely and efficiently despite uneven ground

Lifting heavy machinery such as haul trucks and wheel loaders can be a challenging task without the right system in place. The process of assembling and transporting an over-dimension vehicle requires several steps, some of which may involve locating and positioning the lifting equipment at the appropriate lift points, removing the wheels, attaching wheel stands, and lowering the vehicle to the ground followed by removing the lifting equipment. Thereafter, a multi-wheel trailer would be placed under the vehicle and the wheel stands removed before it is ready for transportation. Using short stroke cylinders without synchronous lifting would be time-consuming, cumbersome and could introduce additional risk if the load is lifted at different heights.

Lifting Precision of a Hydraulic Gantry Key to Humber River Railroad Bridge Reconstruction

When leading Canadian heavy lift contractor, Western Mechanical, was asked to assist in the replacement of the Humber River railroad bridge it selected an Enerpac hydraulic gantry for the precision lifting and replacement of bridge spans over an 8-week period.

Synchronously Lowering an 80 ton Yacht

Synchronously Lowering an 80 ton Yacht

A multi-million dollar luxury sailing yacht was jacked-up two meters to perform renovations. After the retrofit, the yacht needed to be lowered in order to be transported back to the water. Although the yacht was built of carbon fiber, it still weighed 80 tons. And the weight was not evenly distributed; the back was heavier than the front.

Pre-Loading Bridge Cables with a Battery Powered Hydraulic Pump

Pre-Loading Bridge Cables with a Battery Powered Hydraulic Pump

ALE Heavy Lift was tasked with skidding an 800 ton railway bridge over a highway using skidding equipment and steel strands. The steel strands were used as diagonals within the skidding towers and as a connection in a longitudinal direction between the skidding supports. Before the bridge could be skided onto the towers, more than 20 cable strands had to be pre-loaded to the same tension.

Controlled Tightening on Dump Truck Suspension Struts

Controlled Tightening on Dump Truck Suspension Struts

The maintenance team needed to replace the suspension strut bolts on 777F, 785D, 789D and 793F dump trucks. Due to the confined location of the suspension struts there was limited space for accessing the bolts. Existing methods of using flogging spanners often took several hours to replace the nuts, caused minor injuries and inaccurate torque.
