Climbing Crane

Lagerwey’s Climbing Crane is the world’s first independent climbing crane specifically designed for the construction of
wind turbines. The crane was designed and developed by Lagerwey in order to build ever higher wind turbines on both
challenging and remote locations. The crane’s small footprint, easy transportation and quick construction time offer many
benefits for the construction of wind turbines with an hub height of more than 100 metres.

Easy transportation

Due to the compact size and relatively low weight of the
Climbing Crane, Lagerwey is able to transport it by road using
only three standard trailers, without special escort. It is also
possible to ship the crane in only three containers. On the
turbine construction site, roads do not require reinforcement for
transporting the Climbing Crane. The normal requirements for
transportation of wind turbine components are sufficient.

Small crane construction area

A further benefit of the Climbing Crane is the crane construction
area of only approximately 350 m2. This saves expensive square
metres and therefore civils costs on the construction site. In
addition, no piling is necessary on the crane pad/ construction
area. The Climbing Crane brings locations within reach where
large regular cranes cannot operate or where the costs of
deploying regular cranes are prohibitively high.

Quick assembly time

Assembly and disassembly of the Climbing Crane is easy and
takes up relatively little time. The crane is typically operational
within a day, after which the turbine component assembly and
hoisting activities can start. Due to the short assembly and
disassembly time AND transportation on regular trucks, the
crane can be transported to the construction site easily and
quickly.

Hoisting under safer conditions

The interface connection between the Climbing Crane and
the tower prevents any risk of crane instability during turbine
assembly and hoisting activities. This provides a safer working
environment than traditional methods. It is also possible to
hoist at higher wind speeds. Depending on the weight and
dimensions of the load, the crane can be used at wind speeds
up to 15 m/s.

Modular steel tower

The Climbing Crane ‘climbs’ on connection points
mounted on Lagerwey’s Modular Steel Tower
(MST) concept. A Climbing Crane that is suitable
for tubular and concrete towers is also under
development by the Lagerwey R&D team.

Costs

Of course, Lagerwey also builds wind turbines with
regular hoisting cranes. Each wind project and each
wind location is unique and has its own challenges.
For each project, the specialists within Lagerwey will
assess and optimise the best deployment for you
and determine what will be the most beneficial for
your project.
