3-30 ZCC1100H Crawler Crane
3.4.3 Travel on level ground or slope without a load
a) The ground must be firm and flat and can provide adequate load-bearing capacity;
b) Pay attention to trenches and hunches on the ground;
c) Consider the specified slope degree (vertical) and the horizontal slope as well;
d) Avoid toppling over the crane due to deflection of center of gravity. Prevent the hook
colliding with the boom frame, especially when boom angle is bigger;
e) High-speed traveling without a load on flat ground is permitted but not in making a turn;
f) Crane simultaneous movements can only be carried out when travel straight without a
load;
g) The operation should be stable and never initiate and/or stop the operation jerkily.
3.4.4 Travel on level ground or slope with a load
a) The crane can travel with boom frame installed and with a load;
b) When travelling with a load, refer to the load capacity charts and the following load
reducing requirements;
c) Normally, the load should be close to the ground as possible as it can and the range
should be small as possible as it can;
d) The crane can only travel with a load in low speed. The smaller change of the speed, the
better;
e) Avoid swinging the load all the time (if necessary, the load should be fastened on the
rope);
f) The ground must be firm and/, flat and can provide adequate load-bearing capacity;
g) The largest wind velocity shouldn
’
t exceed 9.8m/s when travelling with a load;
h) The load can be put down stably for any possible mistakes;
i) If the ground can
’
t reach the requirement, it must be leveled;
j) The operation must be stable and never initiate and/or stop the operation jerkily.
CAUTION
(1) The load should be in the sight of the operator, and the load shoule be close to the
ground as possible as it can be.
(2) The speed of other movements should be under control during travel.
(3) The maximum travelling speed should not exceed 0.4km/h.
3.4.5 The requirements for crawler crane with attachments on uphill slopes
The maximum climbing ability of a crawler crane is limited by the following condition:
a) The center of gravity of the whole crane;
b) The friction coefficient between roadway and track pad;
c) The transfer between the horizontal and the inclined.
