Bellambie’s extensive range of lifting and pulling equipment
is used in diverse materials-handling applications throughout
Southern Africa.
This range includes Black Bear electric and chain hoists and
trolleys, with enhanced safety features and low-maintenance
requirements.
“The demands of today’s workplace require that
efficiency of operations be improved constantly and equipment for
materials handling play a criticalzenith china zenith vsi crusher role in most industries,”
says Barnie de Clerk, product manager for Bellambie, which is part
of the Becker group of companies.
“Blastone crusher machies manufacturerck Bear hoists, which meet stringent international
quality and safety specifications, are known for efficient
performance, low main-tenance and extended service stone crusher supplier in chinalife.
“The strength and efficiency of this range is in its
sophisticated design, a meticulous manufacturing process and a
reliable support ser-vice.” Black Bear electric hoists have
lifting capacities from 500 kg to 10 t, in models with 220-V, 380-V
and 525-V power supply.
Safety features include an advan-ced electromagnetic and mechanical
brake system that ensures safe operation and simultaneous braking
in the event of a power failure, even under full load.
Limit switches are fitted to prevent overwind on both the lift and
lower operation and a safe 24-V/ 48-V transformer for pendant
control is standard.
A special case-hardened grade 80 alloy steel load chain with a 4:1
safety factor endures harsh conditions like rain, salt water and
chemicals. Contactors with nonfuse circuit breakers allow frequent
and trouble- free operation and a specially designed phase error
relay prevents the motor from running if there is an incorrect
power connection.
Mechanical load limiters are standard for the units five tons and
over and can be fitted to other models in this range. The totally
enclosed construction of the motor housing, which is a lightweight,
yet robust, alumin-ium alloy casting, enables operation in harsh
conditions.
