Operating Instructions
Hydraulic Boom Sequence
When operating a Kevrek Crane ALWAYS use the shortest possible Boom Extension, however, when it is necessary to extend
the Crane Booms to obtain longer reach, do so by always using the largest Boom section then the next largest and so on in
logical sequence as shown below.
Cranes fitted with Dual Hydraulic Extension Booms, have Sequencing Valves present, however, if in the course of operation
the Boom starts to operate out of sequence then return the Crane to your local Kevrek Dealer to have the appropriate
adjustments made.
Diagram below shows CORRECT operational sequence of the Crane Extension Boom sections.

OPERATING INSTRUCTIONS
OPERATING INSTRUCTIONS
1. Raise Main Boom of Crane and Pin Sheave Block Assembly to end of Boom.
2. Run Winch Rope out past Sheave Block Assembly and lay Rope into Sheave Rollers.
3. Install Rope Retaining Pin.
4. Winch Rope must now be lowered down to enable Crane Boom to be extended to required
length.
The Hydraulic Winch has a maximum lift capacity of 500kg constant line pull, this
should be observed when operating the Winch at full Crane Boom Extension.
5. When operating Winch ensure Crane load capacity stated on both sides of Main Boom
is not exceeded.
6. If weight of load being lifted is not known, first take up rope slack with Winch, then test lift
with main boom cylinder.
If Main Boom Cylinder will not lift weight, DO NOT proceed
to winch as this will overload the Crane.
If this occurs retract Extension Booms until the
Main Boom Lift Cylinder will lift the weight, then winching can proceed.
7. Before slewing Crane, ensure load is clear off ground.
8. On completion of loading, remove Sheave Block, retract Winch Rope and return Crane
into the transport position.
