Description

The Boat lifter HE-10 kN is a compact lifting jack for raising loads, designed especially for boating with support plates which can be tilted up to an angle of 20° in any direction.

Deployment/Utilisation

A boat (max. gross weight 40 kN/4 t) can be raised using 4 jacks. When lifting directly with the elevation cylinder, without us of the support arm the lifting capacity is is 18 kN, i.E. 1.8 t per Lifter. Loading onto and unloading from one trailer type to another (eg from a launch trailer to a towing trailer or when jacking a boat up) can be accomplished without the help of a crane. The appropriate trailer is simply manoeuvred lengthways under the raised boat.
When not in use the Boat lifter can easily be manoeuvred with the wheel assembly. Simply tip the device back until the wheels are on the ground. The support arm bracket is then used as a handle.
Due to the slotting connections the Boat lifter can quickly be broken down into three main parts: the Base Plate, the Casing and Elevation Cylinder with hydraulic component and the Support Arm with plate. Thus the Boat lifter can be transported in any normal car and enables loading and unloading to be done by a single person.

Description of device

Basically, the device consists of two main components:

bulletthe hydraulic component (internal)
bulletthe steel outer construction consisting of:
bulletbase plate
bulletcasing
bulletelevation cylinder
bulletcranked support arm
bullethorizontal support arm

4 lifting jacks should be used for every boat to be raised, whereby the devices have to be set opposite each other in pairs with the support arms projecting underneath the sides of the boat's hull. The longitudinal array of the lifting jacks must ensure an equal distribution of the load and must be determined at the responsibility of the user.
Lifting can also be done with two Lifters when appropriate supports are used (e.g. trestle stands).
The lifting height can also be increased by inserting the support arm with the crank pointing upwards.
