Crane hoists and trolleys are the heart of
any overhead crane system, responsible for the vertical
lifting and horizontal traversing of loads across the crane
bridge. Wimac manufactures a comprehensive range of
wire rope hoists,
chain hoists, and
trolley systems designed to meet various
capacity requirements from 500 kg up to 250 tons. Our hoists
feature VFD-controlled motors for smooth
acceleration, electromagnetic brakes for reliable stopping,
and heavy-duty gearboxes for long service life. Available in
standard, low-headroom, and double-rail configurations to suit
different industrial applications and building constraints.
End carriages (also known as
end trucks) are critical structural
components that support the crane bridge and enable
longitudinal travel along the runway rails. Wimac end
carriages are manufactured from
high-strength structural steel with
precision-machined wheel assemblies featuring
forged steel wheels, hardened treads, and
sealed, maintenance-free bearings. Our end carriages
incorporate electric drive motors with
soft-start capability, integrated rail sweeps, rubber buffers,
and optional anti-collision sensors. Available for both single
girder and double girder crane configurations with wheel loads
ranging from 5 to 100 tons.
Crane hook blocks serve as the primary load
attachment point and are engineered for maximum strength,
safety, and reliability. Wimac hook blocks are designed in
accordance with
FEM, DIN, and ISO standards and manufactured
to deliver long-term performance under demanding operating
conditions. Each hook block assembly includes forged steel
hooks, precision sheaves, anti-friction bearings, and robust
steel side plates.
Hook Block types by capacity and duty class
Wimac offers various hook types including
single hooks for standard applications,
double hooks for balanced load distribution,
laminated hooks for extreme heavy-duty
operations, and rotating hooks for precise
load positioning. Hook blocks are available with capacities
from 1 ton to 500 tons.

Electrical Panel
Crane electrical control panels serve as the
central nervous system of the crane, housing all control and
safety components including contactors, thermal relays, limit
switches, frequency inverters, PLC systems, and diagnostic
devices. Wimac electrical panels are built with
IP55 or IP67 protection class enclosures,
ensuring reliable operation in dusty, humid, and harsh
industrial environments.
Main electrical control panel with PLC and VFD systems
Standard operating voltage is 400V 50Hz, with
optional 460V 60Hz configuration for overseas
installations. The panels are designed for operating
temperatures from -40°C to +70°C. For higher
temperature environments, integrated cooling systems can be
added. All panels include comprehensive safety features such
as emergency stops, overload protection, and phase monitoring.

Festoon Cabling System
Festoon cable systems provide a robust and
flexible cable management solution that ensures uninterrupted
power and control signal transmission by safely guiding and
protecting cables along the crane's travel path. Wimac offers
three main festoon system types to suit different
applications.
C-Track Festoon System
C-Track (C-Rail) festoon systems are the
most common solution for standard indoor crane applications.
The enclosed C-profile track protects cables from dust,
debris, and accidental damage while allowing smooth trolley
movement. Suitable for small and medium distances as well as
light and medium capacities in moderate environments
C-Track festoon system for standard applications
I-Beam Festoon System
I-Beam festoon systems are designed for
heavy-duty applications requiring longer travel distances
and higher cable capacities. Ideal for outdoor gantry
cranes, steel mills, ports, and foundries. Supports longer
distances, heavy duty, harsh environments and heavy
industries.
I-Beam festoon system for heavy-duty outdoor applications
Other Alternatives for Overbridge Electrical Supply
As an alternative, these systems are also available in
very heavy-duty festoon configurations
suitable for demanding operating conditions. Besides,
options such as Ex-proof executions provide
enhanced protection for power and control cables, ensuring
reliable performance in hazardous, outdoor, or harsh
industrial environments.
Movable cable channels are also used as an alternative
for festoon at certain project requirements.
Busbar
Crane busbar systems (conductor bar systems)
provide continuous electrical power supply to moving crane
components through sliding collector contacts. Busbars offer a
reliable alternative to festoon cables, especially for long
travel distances and high-current applications.
Enclosed Busbar
Enclosed busbar systems are enclosed in a
fully insulated protective casing. This design both enhances
safety and offers a more compact layout. They are generally
used in indoor environments.
Enclosed busbar with protective housing
Insulted Conductor System
Insulted Conductor System is an alternative
and more economical solution compared to busbar system,
suitable for Indoor workshops, warehouses, assembly halls,
normal environments. But it has shorter lifetime compared
with busbar system
Insulted Conductor System
Open Busbar System
Open Busbar System consist of uninsulated
or partially insulated conductors. These busbars are
designed for use in overhead lines or outdoor areas. They
are manufactured from copper or aluminum and have a high
current-carrying capacity
Open Busbar System
Cable Drum
Cable reeling drums provide an efficient
method for managing power and control cables on traveling
crane components. As the crane moves, the cable drum
automatically winds or unwinds the cable, maintaining proper
tension and preventing cable damage. This system is
particularly advantageous for long travel distances where
festoon systems may not be practical.
Spring-Driven Cable Drum
Spring-driven cable drums use a powerful
spiral spring mechanism to maintain cable tension and
automatically retract cable as the crane returns. This
maintenance-free design requires no external power source.
Suitable for travel distances up to 100 meters with cable
capacities up to 150 meters.
Spring-driven cable drum for automatic cable management
Motor-Driven Cable Drum
Motor-driven cable drums employ an electric
motor with torque control to wind and unwind cables with
precise tension regulation. Essential for long travel
distances and heavy cable loads. Suitable for travel
distances exceeding 500 meters with cable capacities up to
1000 meters.

Remote Control Devices
Crane remote control systems enable operators
to control crane movements from a safe distance, improving
visibility and reducing operator fatigue. Wimac offers both
wired pendant controls and
wireless radio remote controls featuring
ergonomic designs, intuitive button layouts, and robust
construction for industrial environments. All remote systems
include emergency stop functionality and multiple safety
interlocks to prevent unauthorized operation.

Gantry Crane Storm Brakes
Gantry Crane Storm brakes (A hydraulic rail
clamp)
is used on gantry cranes to securely lock the crane onto the
rail during strong winds, emergency stops, or when the crane
is parked.
By applying powerful downward force through hydraulic
cylinders, the clamp grips the rail head and prevents any
unintended movement, ensuring stability, safety, and
protection against derailment. This system is essential for
outdoor gantry cranes operating in open areas where wind loads
and environmental conditions can cause the crane to drift or
slide.

Storm Brake Main Features Components
Clamping Mechanism: High-strength steel
jaws with replaceable friction pads
Anemometer: Continuously measures
real-time wind speed (m/s or km/h)
Control Interface: Integration with crane
PLC for automatic operation
Operator Cabins
Crane operator cabins provide a comfortable,
safe, and ergonomic working environment for crane operators
during extended shifts. Wimac manufactures custom operator
cabins designed to meet specific operational requirements and
comply with international safety standards including
EN 13557 and ISO 8566.
Operator cabin with panoramic visibility
Our cabins feature
reinforced steel construction with
anti-vibration mounting systems,
panoramic safety glass windows for maximum
visibility, climate control systems (heating and air
conditioning), ergonomic operator seats with adjustable
positioning, and integrated control consoles. Optional
features include CCTV monitoring systems, load moment
indicators, and anti-collision displays.
